    A main jet is not gonna lean it out and then get better the higher it turns, so your sayin' its like running out of fuel or the speed stalls out?
    Sounds kinda like its runnin' out of air and catches its breath, what do you do to get it passed the flat spot?

    it just pulls the cable a little tighter.....i didnt adjust the linkage under the cart to make it longer or shorter which ever way i would have to make it not have the extra 1/4" that it has before it hits the floor.
    lol oh so funny yor are.....

    if i just leave it it will eventually get past it and continue to rev if i reach down there and choke it a little it goes right away which is why i am thinking just a little bit bigger main. that is also why i want to see where the slide is in relation to the pedal I just measured today and it is wide open before the pedal is on the floor by further than i thought it was. so my next move is to adjust the linkage. when i checked to make sure that it opened it all the way initially i just pushed it to the floor and looked in and saw it was open didn't look any closer than that. if i go to wot from lower rpm like 2k it revs up to about 4k stalls a little and then moves it might be to much gas and not enough air sometimes when i choke it a little with my fingers it takes right off but sometimes my fingers get a little wet with gas like blowback.....i went from a 280 to the one i drilled which was to big to a 300 which is pretty good i have a 290 i can try

    Gotta be at operating temp and needs to run the air cleaner to diffuse air charge, i doubt it will ever be 100%. A 36mm with a 320 main would be da bomb:twocents:

    yes insurance.....i called my insurance company and asked if while it was on the trailer if it was covered and they said no because it is a mortorized toy it wasnt covered if it gets damaged but that they sold ins to cover it for cheap. 75 buck a year for full coverage if it get wrecked or stolen its covered for 6500 worth

    The way I used to find the correct jet size was to take one of my old Jets drill it out a little larger then fill the jet with Solder Start with a small hole then handrill it larger One drill size at a time until it runs the way you want it Then go a little larger To make sure then buy the correct jet

    thank you for the trick i drilled one several sizes bigger than the one that i had just to see the got several sizes between the one i had and the one i drilled. im pretty close right now and still have other jets to try.
