    ok good . . if it starts with 3 pulls or less you are doing good imo.

    Well i have to say it is running a lot better with the oem jets but still hesitates just a little at about half throttle then it picks up an goes i dont know if its because the new piston and rings havent got broken in yet or what? My needle may be too high, would that cause it to hesitate a little? Well as always thanks for the replies and keep them coming. Thanks Jesse

    It had to pick up the gas because I had the carb apart it took about 6 pulls to start it but i think thats because the carb was dry

    ok well let us know how it is with gas in it, lol.

    if it starts with less than 3 pulls with full choke and is a bit harder to start with no choke, imo your pilot jet is plenty close enough for now which means that your hesitation is due mainly to something else but you still have the 40 pilot if you need to try that again.

    it runs perfectly until half throttle then it hesitates at half throttle then does not hesitsate above half throttle?

    does it hesitate from a dead stop under all throttle conditions?

    in other words, if you push the throttle 1/4 of the way from a stop what does it do?

    if you push it 1/2 way from a stop what does it do?

    if you push it all the way from a stop what does it do?

    From a dead start does good push to half hesitates slightly and at full throttle does as its suposed to, could it be the pilot jet is too small and i need to put the #40 jet back in it?

    unfortunately, since i am not there, i for one can't tell what the problem might be unless you answer each question individually in accurate detail . . all i can do is make an uninformed guess which won't help you much.

    Ok let me try this again 1/4 throttle runs good no hesitation from a dead start to half throttle has slight hesitation at half throttle and from dead start to full throttle has slight hesitation at half throttle then from there to wide open it runs like scalded dog, hope this helps but im still going to try the #40 pilot jet and go from there, i think its pretty close though. Thanks for the replies hope to see more. Jesse

    When you say it hesitates at half throttle, how quickly are you opening the throttle?
    If you hold the throttle steady at half throttle does it run ok?
    Pilot jet is going to effect idle and just off idle.
    I would check that the needle is correct and straight.

    If I hold it steady it helps it some and if I hold it there it will straighten up, as far as the needle it is brand new, would the needle height affect the hesitation any at all? I have it set on the third groove right now should I move it leave it where its at? thanks for the replies

    Try adjusting the needle to the second groove maybe?

    Yes that makes it go up which increases fuel, it might work ive tried it on my 200e because it was backfiring and stuff at half throttle before

    unfortunately i have very little idea what this means . . if you just copy my questions and answer them one at a time it will be more helpful.

    hers another question.

    if you are cruising along with the throttle half open then you suddenly open it all the way, what happens?

    you need to determine if it burbles or just seems like it runs out of gas . . if you can not do this, it is nearly impossible to determine if it is rich or lean in which case just keep changing jets and hope you get a combo that works.
