I dont know if i got a weird engine but when you close the carb all the way, the opening is less a little less than 1mm. It's small enough to where my car shuts off. I compared it to the stock engine i had and the stock engine I could close the carb as far as it would go and it was still not less than 1mm opening.

Does the idle screw I messed with not work like I think it does?

The idle screw changes how far that opening is at fully closed position. Set it to what your stock engine looks like then and go from there.

Thats what I did thats what i was talking about in the other post- sorry if i sounded confusing- I am going to start it up in my garage in a few minutes!

Ah well then it was incorrect on your stock engine too. If your bottoming out that spring your well beyond normal settings. Go find a ruler and find 1mm. Its like 3 sheets of paper. Normally all the stock settings should be good. But given the motor is probably in break-in mode your low-end is probably real rich. Either way maybe 1 full turn over that and thats about as far as you would want to go.

ok- i will break in the motor fully- I have only run 2 tanks of fuel through it. I will put it back to stock and see what happens- thanks so much for all your help. hopfully after break in everything will be good.

you were right artificial- i had to loosen the screw a little bit to get the idle back down to normal. I readjusted the linkage and now everything is perfect! Thanks a lot!!!

Awesome stuff , now you know how to setup linkages. Good luck with the motor. Also be sure to set the ATV on full throttle so its not pulling the carb farther than it should go. Set it so it can go jsut that last bit needed to make it go full throttle. Youll also normally hear the servo get louder and louder once you go past the ability of the carbs throttle to extend.

Yep- everything runs great- it seems like it just as fast as the stock 15. It doesnt get as hot though so I am going to lean it a little to get the extra power. It has a nice smooth power band and its awesome!!!

If your going for max tune. You want to tune by watching the power , smoke and then check temps to see if its good.

What you do is tune it for power , watch that then once you find the peak , richen it 1/8th a turn to put it back to a safe zone. Or you can just leave it how you have it and just slowly turn it out if your concerned the above might be hard to accomplish.

Then go and set your low-end to allow the car to idle 20-30 seconds before loading up and dying from fuel. But you also want to make sure its not boggy.

so as far as the low end goes i need to richen it up or lean it out to make it "die"

Nevermind about the previouspost- i just reread and I understand now. Thanks

ok-now I am conveting to non pullstart- My lhs says they do not have the backplate in stock. Anyone no what I need and where I can get it. They have everything else like the non-ps flywheel and starter box
