jas280z Posted June 29, 2010 Share Posted June 29, 2010 Just reinstalled my engine and have been breaking it in/trouble shooting. I was experiencing unadjustable low idle ( 600 rpm) when it warmed up and diagnosed the problem as a vacuum leak. Vacuum gauge showed that I was getting 7 lb of Hg at idle. I started poking around and could actually hear the leak coming from the front of the intake manifold. Some squirts of carb cleaner and I found that the could start valve was leaking. Pulled it off, changed the gasket, a very light coat of RTV and fixed the leak. Vaccum gauge now shows a steady 11.5 lb of Hg. and I have full adjustablility of the idle. Vacuum is still a little low, but I think my bigger cam (schneider Stage I) may explain that. Quote Link to comment Share on other sites More sharing options...
