Jack, before you do a compression check pulling the valve cover might be quicker if it's the two bolt in top type. That will show a stuck valve/misplaced pushrod/collapsed lifter right away. The only thing it won't show is a burnt valve or blown head gasket (could be blown on the outside instead of between cylinders?). Or even worse, a hole in the piston. Of course it would have a lot of blow-by/crankcase pressure if that was the case, should be obvious from my unfortunate experience!

I've been all over this engine checking for vacuum leaks, open taps and the like before replacing the carb.

Again this was one of the items checked before the carb was scrapped, but I could do a spray test with some WD40 around the #6 runner and see if that picks the cylinder up. Still, I say valve or push rod. > > Re: check the compression on #6. > > Not yet, but time is a premium commodity and tonight's ration includes a compression test. My guess is a burnt valve, the cranking compression test says that one cylinder is a in a no load condition. Doesn't mean it couldn't be a bent or disconnected push rod as you mention, that would be preferable. My luck or lack of it, it's a burnt valve. > > Re: I had an engine that had a nasty habit of dropping the #6 intake pushrod. > > This would be lovely!
