    Tecumseh Clearance Sale

    I've got a bunch of mini-bike correct engines (and a few that aren't) that I need out of my way.

    Gx160 valve cover clearance

    I have a gc160 head that has 1.3 rockers and 26lbs sorings, I think rockers are hitting valve cover. I dont have enough space to put a spacer so. Can I remove the baffle inside? If so how can I make sure oil doesnt leak out breather hole?

    Aw dang it

    Guess I didnt update my build off bike in time and my thread is closed. Just put my swiss cheese machine shop from hell sprocket on and it has clearance. Oh well I'll just make it a regular project thread. Look I had my gloves in the shot and everything. How sad. Weep.

    HS50 valve clearance

    I was looking at a pdf of an old Tecumseh manual and it called for .004" valve lash on the intake and .010" on the exhaust. Is this right? Seems like a lot on the exhaust side.
