I am having trouble getting my new 2056 with a 9590 cam to idle. When I start it is idles around 500rpm or lower and I can't speed it up with the by pass screw.
I am running L-jet injection I hear a hissing sound when the engine is idling but I cannot find a vacuum leak, plenum couplers are new and all other hoses are in good shape. I can't find the hissing with a mechanics stethoscope so I was going to try to find a leak with propane but it has been too cold to work on it lately. The idle does seem to get a little better after it has warmed up a bit I think, it has been several weeks since I have had it out. One question I had is does the new cam require any change to the mixture? if so how do I go about adjusting the mixture? Thanks in advance for any input |
