    Yes stock a lot of valves but do run out then get more made.
    Just a word of warning for anyone out there working on the older Husky's.
    NEVER-NEVER assume it is stock with all the parts avalibility problems in the past God only knows what was used to get them running. And he ain't saying.

    Just a tought .. Is it possible that I've adjusted the decomp to tight?
    when changing the oil I hold the decomp and kick the engine över 8-10 times to get all old oil out..

    Is it possible that the decomp opens that much?

    Maybe a stupid question, but everything feels weird with this engine/rebuild..

    Anything is possible but should have felt decomp lever moving.
    This motor has the cam rocker opening both valves.
    Newer 04 and up decomp only opens the Rh exh valve.
