frequent high idle and stalls 1986 trx 350
hi all, i just rebuilt my 350 from the jug up. new rings fresh hone, rebuilt head, new gaskets and a carb rebuild also. having an issue with running, sometimes it runs great and others it will cut out and stall. when it does this i check spark which is fine. fuel seems to be getting there also. when it dies i try to restart it and it doesnt want to go. if i let it sit a while it will restart and run fine. then i will ride for a bit and after a while when i stop if i leave it in gear it will slow down til it stalls. if i catch it before it stalls hit neutral and feed it some throttle it will rev up and hold high idle. i try to kick it down by feathering but it will stay high idle. the only way it will kick down is to drop it in to gear which after it learches forward it calms right down. after i do that i can stick it back in neutral and it will idle fine, no problems. it only acts up if it stalls, or if i catch it before it does.
any ideas? thanks in advance -Johnny
