motor will idle and run fine at wot until it warms up. then will not idle but still run fine wot. the only way I can get it to idle is to trim the motor way up. Any suggestions? Have run 2 cans of sea foam and cleaned the carbs. Is their a float setting on this model? |

Are you using Champion QL77JC4 plugs, gapped at .040. If not do so. You might also try the gap setting of .030 .
Carburetors do not come and go. If they're fouled in any manner, they stay that way. However, the float setting is as follows:
(Carburetor Float Setting)
(J. Reeves)
With the carburetor body held upside down, the float being viewed from the side, adjust the float so that the free end of the float (the end opposite the hinge pin) is ever so slightly higher (just ever so slightly off level) than the other end. And when viewed from the end, make sure it is not cocked.
Thousands of parts in my remaining stock. Not able to list them all. Let me know what you need and I'll look it up for you. Visit my eBay store at:
