Re: #6 not firing? Not even a squeak. Re: Check for a vacuum hose off the tap on the intake Check! I've been all over this engine checking for vacuum leaks, open taps and the like before replacing the carb. The engine idles rather effortlessly now, by comparison. Re: or a loose intake bolt Check! 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! I'm not looking forward to pulling the head.(bad back and I work alone) Thanks for the tips, I'll post my findings.
