i just fixed my 72 honda 350 and adjusted the carbs (idle mixture, etc.) and now when i'm in neutral i can rev the engine and it sounds great. BUT, when i'm in gear and want to accelerate, i have to twist the throttle only halfway. it accelrates fine when i do this. but, if i try to give it "shitloads" of gas while the rpm's are at, like, 3000 or something it sputters and makes a gurgley sound and will not accelerate. why? is it my fuel/air mixure? i don't think so, because it would do this when i'm in neutral, but it doesn't. can anyone help me?

Mike,
Did you do the timing and valves on that bike? If the bike has a stock motor and the carb/jetting are stock you shouldn't have any gurgling under load. There are all kinds of things to check, but I start with the ignition timing and the valves.

wont accelerate under load huh?? how the plugs look?? i think if it was timing, it'd gag in nuetral too. toss on another set of usable carbs if you have em. be sure they are sealing to the intakes well. pulling carbs apart when you dont know exactly what youre doing can be risky.

aarons right, it could be alot of things.

He rebuilt the carbs already I believe from one of his other postings, but if Jeremy can do timing I'm pretty sure anyone can.

i know, i sent him parts remember?? as anyone who's decided to pull apart carbs and doesnt know what they are doing, it can be a disaster. now im not saying he doesnt know what hes doing, but it could just be a matter of something not reassembled correctly. if he has another set of carbs that he knows are good, if he tries those and it works, that solves the problem.

i think i know what it was. i was riding yesterday and it was doing it again. at the next stoplight i look down and the choke is on. i shut it off and it went away. the thing is, that choke lever is really easy to turn and i think sometimes, if i'm going fast enough, the wind could make it switch to the choke position. anything i can do about that? an expert helped me put the carbs back together. i am confident about them. also, when there is some hesitation only when my bike is going past 50 mph, does that mean one or both of my high speed jets has problems? when i slow down to under 50 mph, the problem goes away. would the fact that i have a passenger on the bike matter? my girlfriend and i go out for rides sometimes.

maybe not problems. maybe the wrong size. check your plugs. you can completely pull the chokes out of those carbs and plug the holes. mine starts fine with out them. hot or cold. i have found my leg will hang on the lever and open and close it. you could safety wire it in place, but them you wouldnt be able to use it. maybe you can put 2 of those little locking plate tabs stacked together to hold them in place. i dont know. maybe some gum. or mikes old favorite, duct tape. what ya think aaron??
