picco problem

       Remove this ad - become a site supporter!
i have been having a hard time with this motor as it keeps going lean on me.i ran my truck into a wall not to long ago and ever since its been acting odd.could a bad manifold seal cause a motor to go rich to lean??? the motor seams to have alot of fuel over it and that is the only area that i can see it coming from.

i suggest taking the motor apart including the carb... cleaning everything and put it back together... make sure you grease all the o-rings and seal the back plate with some rtv gasket

if bad enough an exaust leak can cause an engine to go lean,it'll reduce the amount of pressure going back to the fuel tank.
