Re: Still bogging down after alot of work

Have you owned this engine for some time, and if so, did this engine ever run properly for you, or is this a engine you just picked up recently?

Are the original carburetors on it now? If not, what carburetors are on it?

Did you manually clean the three high speed jets located in the bottom center portion of the float chamber?

There was a service bulletin that Mr. Reeves sent me that did fix the problem. Just be very careful when you do the modifications on the pickup tube. Meanwhile I will try to find it.

While I am looking the simple fix is to bump the choke as you give it gas.
