No idling on 351W engine

[cnefalcons]

Good Day All<br />I have a 1977 33 Carver Mariner with twin Pleasurecraft 351w engines. One will not idle but runs great at 1100 rpm on up.<br />Have changed all ignition items inc coil, has even compression on cylinders and ignition timing is good. Fuel pump pressure is good. Has clean fuel line with new filter. Has a Holley 4 barrel. Any suggestions???<br />Thanks in advance for any contribution.<br />Mike

Re: No idling on 351W engine

I had that problem last season, nothing i did made it idle nicely. Turned out the manifolds and risers were leaking and wetting out the plugs. Its a little obscure, but anything is possible.
