Brian,

Do you mean the reed valves that are in the intake manifold assembly?
If so, I didn't get into these as they were installed with new gaskets
and I assumed they were checked out and no problems found by the prior
owner.

If these are what you are think the problem is I'll certainly tear into
them after your positive response

Thanks, Mike

I have had a fixing screw come loose and hold an inlet reed valve
open. At the cost of pulling the carbs off to look, I'd think it's
worth a look?
