Yamaha Ty80 Carb Settings

Featured Replies

Hi,

Got a little ty80 but would like to know the,

standard carb settings?

Mixture screw?

Main jet?

Needle?

would be very helpful :crying:

TY80A takes a few kicks to get her going. Would not idle well or at all. Screwed the air screw practically all the way in. Runs better. If the air screw is all the way in, does this forcibly mean the pilot jet (34) is too small?

Thanks.

 It means it is plugged up. Clean the carb.

Yep already done. Complete carb rebuild. Used cleaner and air. Still same issue.

 So you pulled the jets and made sure both passage ways on the pilot circuit were clear? Rust in the tank?

Did all that. Noticed some tank crud on tank side of fuel filter. Carb bowl was not too bad. But I think you are correct about tank debris. Time for a tank coat. I think maybe some super small debris may be the culprit. Thinking too about crank seal job  

Thanks. 

I don't think carb cleaner is that effective anymore, maybe an ultrasound cleaning would help.
