What should i check? what am i looking for? | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Josh_51GMC, did you get that vacuum gauge yet??? When you say it "dies" do you mean it actually stops running, or does it hesitate and possibly backfire through the carb? You told us a while ago that you checked the carb and the accelerator pump was giving you a shot of fuel every time you worked the throttle, so leaning the mixture shouldn't be the problem. When you get the vacuum gauge put it on a manifold vacuum source and tell us what the readings are at idle and what they do when you attempt to rev it up. | | | | | Joined: Apr 2011 Posts: 174 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2011 Posts: 174 | yes i got the gauge, it reads 16.5 PSI idling and slowly varies down to in-between 7 and 3 before it actually dies. like stops running. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Josh_51GMC, those readings indicate a plugged exhaust system, try dropping the exhaust pipe off and see how she runs and the gauge behaves | | | | | Joined: Apr 2011 Posts: 174 Wrench Fetcher | | Wrench Fetcher Joined: Apr 2011 Posts: 174 | will do, would that be why when we have her at idle, theres a bit of a hissing noise?
If thats not it, what should i look for next?
