Just got a Manco silver fox 606 and po put a Briggs vanguard 9hp on it. They have the throttle rigged up but it sticks and doesn't work very well. What is the best way to go about hooking up the throttle and getting max rpm out of the governor?

Here is what I've got
Ohh come on I’m not even at this level. are you capable of taking that whole throttle linkage apart sanding it clean then spraying it down or throwing it in the garage sink? Think all nice shiny metal... and putting it back together? until you do this that is not going to work... if you would just clean it all and re-assemble it looks as if it would work well.

I would disassemble this clean every part of the throttle linkage to look new. even maybe taking my time?? And that throttle system would work like new in a half hour tops. I wouldn’t have had to ask what was wrong on here in the first place. it is caked with dirt. Your throttle return spring is dragging against packed dry dirt.

Aw, come on. Can't I just rub some mud on it and then leave it out side for a year or two. After you do what is suggested in post #4 and #5, add a little grease between any of the moving parts. By the looks of your linkage, how is it not OBVIOUS to you that it won't work correctly as it sits. Also welcome to the forum. We try to help solve problems for other members. Sometimes it requires a little work or elbow grease on the part of the person posting the problem.

It might suck a little, but listen to these guys! They know what they’re talking about, both of ‘em :smartass:

not to mention that’s just nasty :lolgoku:

really cause cause they act like a couple of jackwagons lol way to welcome someone to the forum. I'm plenty capable of any mechanical work. I figured cleaning it was a given. Zip ties and springs just randomly threaded on is not my idea of the best way to hook up the throttle and adjusting the governor to get max rpm. Maybe the governor cant be adjusted? or to get max rpm it should be removed? Not sure how the governor works on these little things. I would assume there mechanical version of a rev limiter, like what is used on what I'm used to working on. Those are electronic dial it to 6k and you're done. This being mechanical I assume the linkage would need adjusted lengthened or shortened idk. From the sounds of it maybe you guys don't either. If I wanted degrading responses with no actual useful information I would of just asked my wife. Thanks for the responses cant say they where any help at all

Calm down, please. :surrender:
Okay, I looked at your photos, and after the clean find your model number (not serial number, that got me on a pressure washer) and find the parts diagram on briggs and Stratton‘s website. Make sure your engine is set up factory style, then work towards the pedal. Make sure all your linkages are free and moving. I don’t know anything about the Vangard so I can’t help with the governor.

And please give these guys a break, thepartsguy helped me personally with my Streaker, and panchothedog is a little to the point, he doesn’t mean to be rude. These people try to help quickly and sometimes that comes out as rude.

have nice day! And please don’t leave!

I was just thinking about safety when I said oh come on.. my bad I was not trying to be rude to you as a new member! I have watched throttle stuck carts go places! most of my sister hair ripped out by the chain! been on a throttle stuck gokart myself with no kill wire. my first gokart was destroyed after my friend sat in it for less then two minutes! the throttle stuck she was thrown from the kart onto the road and the kart slammed a tree destroying the frame. I was like 12 years old and gutted. get the throttle cleaned up and have fun!

I'm calm as a cucumber but stating "I wouldn’t have had to ask what was wrong on here in the first place" is not quick to the point help as a matter of fact its not help at all. I'm all for helping others and having fun along the way but degrading rude comment are not helpful or fun. Its obvious that the linkage is dirty and needs cleaned and lubricated very obvious. I however don't know how the governor works on one of these most things I deal with don't use them. That is why I asked what is the best way to set up the throttle and adjust the governor for max rpm?

I understand the cleaning of the throttle and freeing it up that is a given. But doesn't answer my question? These engines to my understanding was mostly used utility which try to maintain a lower rpm for economy and sound. The PO in an attempt to increase the rpm added a spring, but I would have to believe there is someway to increase the rpm in which the governor limits it to with an adjustment? Maybe there isn't or maybe no one else knows how a governor works either idk.

Cool as a cucumber, I like that one. I’ll get back to you on the governor, but I don’t think anyone here has a Vanguard on their kart. I think this is a big misunderstanding. Whenever it’s clean take a few pictures of it. :thumbsup:

To control engine speed, a mechanical governor uses gears and flyweights inside the crankcase to detect changes in the load and adjusts the throttle accordingly.

If you're operating your small engine under a light load, the carburetor needs to deliver a relatively small amount of air-fuel mixture to the combustion chamber. This is all controlled by the crankshaft - which spins quickly under a light load and slowly when the engine is working harder.

When the crankshaft spins quickly, the flyweights open up, putting pressure on the governor cup and crank. This closes the throttle, limiting the air-fuel released into the engine.

When the engine load increases, the crankshaft spins more slowly. This leads the flyweights to relax and the throttle to open back up. Governor springs hold the throttle in the desired maximum speed.

When the governor springs are altered, it effects the tension between throttle and the governor.

before you mess with the Governor settings itself at all I would clean it all up and get it shiny and oiled. that alone could gain you rpm and help with throttle return. And is where I would start. I understand how the weights Inside the case kick out and hit the pad. Your adjustment should be a flathead screw. You can adjust this flathead screw sticking out of your governor arm wrong and backwards. leading to ungoverned WOT on first startup. this is why I suggest just a cleaning before you go messing with it.3C9E3F06-E601-48B9-911C-E1A06C798D49.jpeg

What is your end goal as far as the governor is concerned? Do you want to retain it or remove it? Because you can safely remove it to get a few more RPM out of the engine without blowing it up. But the throttle hookup will be drastically different. And most people would have had the courtesy to clean up everything first so clearer pictures can be taken so we could see exactly what we were working with before complaining. They also would have lubricated and freed it all up too.

I wasn't sure if the governor was able to be removed very easy or not. The end goal would be to safely raise the rpm range with out damage from over rev. obviously not a crg kart that I expect to be turning 6-7k. but 4-5k would be alright. I've never seen more people concerned with dirt lol I would think to pretty much anyone that it would be obvious that is needs cleaned and lubricated. Maybe its not and maybe that's the kind of people on this forum idk. This was posed hours after bringing it home and I was trying to gather information before tear down. It cracks me up that that literally every response is its dirty and nothing about the zip tied linkage 40 washers or chopped of spring just randomly threaded on? You would think for someone that just joined the community to learn some information other members would have the courtesy not to degrade and make fun of them in hopes to grow there community. cleaned up or not the linkage will be the same linkage I guess I just don't get the satisfaction from making remarks like that to people trying to learn maybe this isn't the community for me

What was apparently obvious to you was equally obvious to those who replied. Taking these responses as rude is unfortunate, I can assure you there are very few if any rude folks on here. Admittedly, what you have is a mess both mechanically and literally. Removing the governor can be straightforward, there are tons of videos on-line about it. But like anything else, it's possible to get in over your head. You will have to remove the side cover of the engine (the side with the output shaft). That alone will scare some folks off. Simply tampering with the governor linkage is not a good idea, as the mechanical parts of the governor are not designed to withstand excessive RPMs, and they could disintegrate inside the engine, causing havoc.

To get the most out of the engine I would bend the plate down And put a cable clamp on the shroud that pulls the linkage with the long rod on it directly. and then delete the linkage I told you to clean intierly. But as above posts said if you rev it to high you risk flinging the gov apart inside the case. Now the bigger question? metal kick out weight on the cam that functions as a compression release? They fail at governed rpm. I would be worried about the weight and spring flinging off the camshaft at above governed engine speed. A9018E99-8077-4506-BEDC-1C8D1C817891.jpeg

We have a lot of people come in here with no experience or knowledge and we go at the most basic level until skill level is established. It’s now obvious that you are not a beginner.
