Did a search but just got more confused. Trying to decarb my Ficht and the engine tuner can says to attach to the "primer lever valve"....the only schrader valve I can find is the pressure check valve which I had read should not be used for this. Someone help me out on this. I read seveal post on other sites with long complicated prcedures that just seem like overkill...there has to be an easier way.
