intake is alum push rod actually u should put it in backwards as the alum rod wears thin in one spot and bends - so if you flip it backwards, it lasts twice as long. Valve gap is critical for the compression release to work otherwise she wont crank, wears out the drive gear and you think its got a bad battery or starter problems.
