help with predator throttle setup

[kspray]

Got the cart put together and ran it one time. Now it seems to not want to start or stay at an idol....what could I be doing wrong ......

 

[Doc Sprocket]

Basic troubleshooting. Air, fuel, compression, spark, timing. What's out?

Note: After governor surgery, you may have to adjust the idle speed screw, and some engines like a little throttle input while attempting to start.

Please try to describe in greater detail what's going on.

The first time I cranked her I gave it a third of throttle like the manual said to do, she kept running as long as I kept at a third or more, I stayed on the throttle from there and she ran. I took it around the block two times I killed it to see how it would act on a re-crank... Now she won't start and seems like a fuel problem.....maybe flooded?

Pull the spark plug out. Shut off fuel, and pull the rope like 5 times to clear out a flooding problem. Turn fuel back on, put plug back in. Put choke to full choke. Do NOT touch the throttle. Pull the rope till it starts or trys to start. If it starts give it a LITTLE bit of throttle just to keep it runnin and warm up. Open choke after its warmed up.
If it only TRIED to start, open choke,and pull rope a couple times but NO throttle, untill it starts n runs. Your engine still has the govenor right? My predator will ONLY start with choke closed. Even warmed up to operating temps.... But it starts first pull ,every time .....
Try the choke and no throttle. .... It works on mine all the time...

Will do as soon as I get home, it still has the governor. also is the idol screw the little screw with a spring on it that seems to stop the throttle the tighter it is tightened? I'm trying to figure out wich screw is the idle speed screw..

 

[Doc Sprocket]

I'm not clear, did you remove the governor, or not?

The idle speed screw is located on the carb. The point of the screw holds the throttle plate open to a minimum. Usually characterized by a spring wrapped around it, but not always. If it is backed all the way out, your engine likely will not idle. Turn it in until it does.

Will do as soon as I get home, also is the idol screw the little screw with a spring on it that seems to hold the throttle open the tighter it is tightened? I have it backed all the way out as of now.

No... 'that' sounds like the throttle limiter... the idle screw is 'on' the carburetor itself. On the clones/HF212/Honda 6.5 its a black plastic phillips(+) "screw head". "That" is a VERY touchy screw... so remember the position it's in... 1/4 turn can raise your RPMs audibly noticeable... or as referenced, prevent it from idling.

As far as your 'idle' issue... you can try to also watch this...
Spring localization for a clone's governor...
... that is my motor and I have removed the governor spring at one time in the past(cant remember why right now) and 'not' remember/find where they 'properly' connected back to. From what I remember, after I removed the governor springs) the result was it was really hard to start... and it wouldnt idle(I had 'thought' I put the springs back correctly... and was wrong)... the vid will 'show' the locations and the proper/factory movement(s) of the arm... as well as where I connected my throttle cable(I connected mine from the rear(vs the side, like most do) of the motor)... you can 'pause' the vid to compare to yours(only 'guessing' your running a clone... only skimmed the replies... battery is bout dead on my laptop... so Im rushing alil).

Im NOT saying it's the problem... but couldnt hurt to check the vid n see if you can compare it to how your springs are connected(you 'may' have a spring causing too much pressure/drawback... or none at all(depends how your springs are installed).

HINT: Before removing/changing anything... take a short vid/pic of it 'before'... 'that' way youll have a reference to your motor... vs someone elses of similar build.

I apologize if Im off base on your info needs(like I said... just skimmed this thread), thought Id put my .02 yen in.

Governer is still in, I haven't fooled with motor at all just installed it in the kart, hooked up the throttle and that's it, after putting gas and oil in it I pulled a few times while it was choked, once started I ran it for a,while and then jumped on it and went around the block . It never did idle I had to keep it at 1/3 throttle to keep it running. After stopping and killing the cart I tried to start it again and now it will not start.

 

[kspray]

Ok guys the engine runs fine the only problem is when I start it the cart wants to take off, I thought the clutch would only engage after it was throttled so much... But instead it seems to stay engaged and is causing the cart to want to take off on me before I get in. I can't figure this out please kart gods help me get this down before tom. you all have helped so much by the way

 

[OzFab]

Let me guess, you wound the idle screw in? if so, you went too far & now the engine is idling above initial clutch engagement speed; back it off a bit...

 

[kspray]

Never fooled with the screw yet, but did locate it and seen that the spinning black peice ontop the carb wich connects to the throttle doesn't close all the way to the screw so I seen no need to tighten it because doing that will seem to keep the throttle open even more....seems to me that the black piece should close to the screw point wich it doesn't

 

[firemanjim]

Does the throttle arm have enough slack that it moves freely? If we could "see" your engine and what you have, I am almost certain we can get it fixed before the fat man gets here....
I dont know how you set up the throttle. The throttle arm should move freely with no binding. Make sure you can ,....... whooaaaaa PUT A RETURN SPRING FROM ARM TO SOMETHING so it forces throttle closed. Do you have one? My pedator HAD to HAVE one or it would idle high enough for partial clutch engagement. Snap a pic n upload. I will try all night if i have to to help you get it fixed by morning..... HURRY we runnin out of time.

 

[kspray]

Haven't been able to post pics from phone I havent gotten it figured out so when I get to a computer o will definitely put a pic up....sorry guys for no pics but I appreciate ALL the help and it should be ok by tomorrow. I bought my son a tv so he has a big present to wake up to so its ok the kart will be extra lol. I will put the spring on tomorrow and hopefully that fixes it wich I think it will. If I had a bit I would do it now but no bit to drill through the throttle lever so I can't do it tonite but it will be done tomorrow...you guys are such a huge help and I hope you all have a merry Christmas! This thing will be running tomorrow! THANKS TO YOU GUYS....HAPPY HOLIDAYS AND ENJOY YOUR CHRISTMAS!!!!!!!!___

Hey you dont need no stinking drill.... go back and look at where i hooked my spring to. No drill involved. It hooks to where the cable goes.. look at my pic on page 1... Mine hooks there, then back to the muffler i made, but you can hook it to anything on the side over there. Use a short piece of coat hanger to make a hook/extension....
Merry Christmas to you and yours as well!


You know, its a situation like yours, that Skype or video phones ,would be SO HELPFUL. Gonna have to put that on my things to do list for next year.. lol

Soooooo,...... what happened?
