the manual shows an exploded veiw of the engine and carb. it clearly shows two things under the carb... one is a meatal ring that resembles a thin walled washer and an o-ring. the o-ring on mine was not there.

i just went the the auto parts store and asked to look at there o-ring assortment. found one just a hair bigger than the carb barrell and put it in...... the metal washer first then the o-ring . i also pushed in on the carb to seat it while i tightened the carb screw


i immediatly knew i had found somthing when i tried to start it for the first time afterwards....it was so rich it wouldnt even run

then had to lean it out......... no air leak any more...................hope this helps.................cantw8tofly
