I was wrong about the cam compression release. It's not a compression release at all, but instead an ignition advance mechanism. It had a really retarded ignition setting when you pull and after the engine fires it advances. Learn something every day.....

Other than that, I stripped the block and painted it and am getting everything cleaned up and nice.

I was thinking about some pics MDB put up last week and got to thinking about big valves. Then I remembered some potential candidates in my parts cache:





What do you think? The intake is supposed to be 90% as large as the piston, right? Gives new meaning to "valve overlap." :001_tongue:

Good call; the intake valve is in fact a 6mm stem with a 2.180" head. The exhaust is 5/16" stem, 1.60" head. And yeah, titanium. :shifty: I also have some 7mm stem intakes and some other 6mm intakes with a jet black diamond-like carbon coating.

None of them are going in my Briggs, but I thought the pictures would be good for a chuckle. :clown:
