Since I am sure this is pre EPA due to the fact it looks just like every other little Carb I have messed with, can u shed more light in the adjustable main? I feel as though I might be missing part of the puzzle. Small engines have never been my thing. I have always played with cars and trucks...

I have a guy at work that is willing to buy the tec so I can to that route. The Subaru is a great engine. Always starts on the first pull and seems to be ok on power. I think I will buy a pred and out it on the yerf and sell it unless its something amazing after its all done. Chris

The Subaru is 6.5hp. I'm only keeping one so its the predator or the Subaru. I will give up some longevity for power. But its a cost thing with the tec. Just the recoil is half the cost of a pred. IF the Carb needs more parts or replaced its more money and its still unknown how much life is in...

I have been working on my Manco with the 6.5 Subaru and that engine has been a wonderful experience. I just started working on my Yerf with a 6.5 Tec and good lord. I knew it had issues when I bought it, but wtf. The carb was screwed. I cleaned it up and got it running... for a minute. cant get...

I'm not sure about the spindles since both side were almost the same. The washer does not touch both races. There is a machine bushing that is smaller in diameter that contacts the bearing and inner race but does not touch the outter race. I ran into the problem the first go at putting it...

Just thought I would give an update. I have been playing with the 6" driven that came on this kart. I put a yellow spring in and have it in hole three. It was a pain to out back together but what a difference it has made. The engine revs right out now. Mid range power is much improved. I like...

It would not be comfy if it comes off for sure. I may add a piece of square tube across the brackets and weld them to it and the frame. I'm sure the engine mount will fail again so I will be in there someday again. Chris

I don't have any pics of the weld after and its all back together. I will say I didn't do the welding. I have a friend that welds gas line bring his welding truck over and do the welds. He has been welding for 13 years and I trust his work far more than my own. Its all stick welds so that might...

I opened up myth driver and wow. It was full of grease. People! Lol. I cleaned it all up and used graphite on it. Then I took the driven apart and cleaned it. The spring was in hole 1 and I moved it to 3. I'm going to guess the spring is whipped cuz I moves it 1 valley and it had no tension...

The springs are def the way to go! How have I never seen these? Guess Rome wasn't built in a day... lol. Thanks for the links. I still need a 8 tooth sprocket so I will grab some springs and lube while I'm at it. Chris

That is a nice ride. Did u get more low end out of it like u wanted?

So I got it all back together and driving. In stock form with the worn out belt its way better than it was. The steering is nice and smooth. No more jerking steering wheel or going where it wants. The motor is nice a stable and it acceleration much smoother. It has a lack if low end stock, but...

First thing I need to do is find a tach so I can get data. Other thing I need to do is clean up and lube the driver to make sure its working exactly as it should. Chris

So as I have poured over the internet, the data, the craziness, it seems there is nothing on modding a 30 driver. This seriously boggles my mind. Once I figured out how they worked I had seen it before. A 30 driver is very similar in engaging as a RC nitro engine clutch. While those you can get...

Then we did some cutting and welding to fix the breaks and the bearing retainer mount. Didnt take long at all. Bearing retainer mounts: Engine mount fixes: This picture looks like its not right as far as square, but the tape does not lie: While the motor was off I had one of the guys...

So now I have dove into the back end of the XTK. WOW! While I knew something was not right I was surprised. The belt was way to long or stretched or something and the driver was coming in about 75% before the belt would grab. The belt just rode up the driver til there was enough tension to...

The Manco has a 6.5hp Robin and the Yerf still has its 6.5 Tec. The Robin has to be the smoothest most quiet small engine I have ever seen. The Tec... its not running. I have to clean the carb. Once I have the Manco back together I will move to the Yerf. Chris

Now for some pictures of what im talking about: The Manco and the Yerfdog: How close the tie rod end was to the tires before: The lack of the spacer/washer after the long spacer: The wheel spacing fix in place (ome washer one machine bushing): The clearance between the tires and rod end...

Manco XTK 706b renew and mods now with pics Earlier this week I started going thru the Manco 706b I picked up last weekend. It was a runner but it has issues. The steering was super sloppy and the belt was so stretched the driver was 75% engaged before the belt would grab. That was causing...

I'm not an expert by any means, but I'm gonna guess it had 10 tooth sprocket on the jackshaft. Chris
