I have a newer 3.5 4 stroke. It starts fine but wont idle right. Also to run at full throttle, I have to pull the choke out about 3/8 of an inch. I cant figure this out. any help would be appreciated

Re: 3.5hp tahatsu 4 stroke running problems

Welcome to Iboats,

2 issues to check :

If that model has a small mesh filter located inside fuel **** as same 2 strokes model, you could have a restriction there. Remove complete fuel from tank into a container, remove fuel ****, clean protruding mesh filter well, clean internal tank also. Add fresh clean fuel to tank.

If idle is too low, once engine is sufficient warm, turn idle speed screw CW to increase idle rpm to a point that when gearing forward under load engine doesn't die, adjust + CW untill engine remains on.

Happy Boating
