Inliners International Forums General Discussion Engines HEI vacuum advance problem

Bought an HEI distributor on e-bay for my 292 lump port head engine. Tom Langdon strongly suggests using vacuum advance, but each time I hook up vacuum line to the distributor, the engine coughs, sputters, and just doesn't run right. Tried re-timing all over the board, but that doesn't help either. It's as if the distributor is advanced too much too fast. Once I remove vacuum line and plug it up, the engine runs great. Any suggestions? Thanks in advance.

I had a similar problem when I put an adjustable vac adv in the HEI on my 292. The problem was mention in the docs with the adj vac adv, and there was a limiter included in the kit. It's a known problem and there are several limiters available here are links;

I installed the limiter and adjusted it, problem solved.

Thanks, Larry. A Crane limiter is on its way.

Larry, That is some good information. Thanks.

Gearge, it did take some trial and error to find the correct adjustment.

Beater, glad to help with what meager knowledge I have.
