I have a 1983 Johnson 4hp 2 cyl two stroke and have it in pieces - my question is are the four reed valves suppose to sit flat all the way closed when the motor is not running? All four are up slightly when I look at the valve plate.

They should be flat, but if they will close with the slightest of touch they probably are ok.

They are all straight and up about .025" they close easy - I took them all apart and cleaned under them as they where full of crap and not closing.

Hm.m.m.m, that begs another question. Where did the crap come from? That should be probably the cleanest part of the engine. Let's hope there are not other problems in there.
