I agree, don’t think closing hood had was the cause. But the carb was a fresh rebuild 3 weeks ago. Tuning absolutely perfect. Then suddenly ran bad.I'll bet closing the hood and it running poorly are just a coincidence. Could be dirt in carb etc. Figure out why you don't see the timing mark
Has electric ignition. No points. Not an HEI Dist it’s looks like an original Dist with updates electronic eye.Gap on points too close
Hard to start now.I'll bet closing the hood and it running poorly are just a coincidence. Could be dirt in carb etc. Figure out why you don't see the timing mark
Does it start quickly, same as before and run poorly or is it harder to start now?
Thats what happened to my 72 Suburban distributor, the upper bushing or aluminum body was so worn out the points were all over the place.Gap on points too close
This one doesn’t have points. It’s an electric setup now.Gap on points too close
For the most part any engine that was not designed specifically to be what is called a "Clearance Engine" where they expect a timing belt to break, you'll have interference issues between the pistons and valves if the valve timing goes off by a little. While each engine is a different beast when valve/piston clearance is concerned most will have problems.I guess what I really need to know is do these motors bend valves if they jump timing???
If someone knows please let me know.
thanks
Agreed. And if you don't have a leak down tester, simply remove all the plugs, lock the throttle open and turn the motor over by hand with your finger in each plug hole. You going to know real fast if you have a weak or dead cylinder.The easiest way to tell if you have a bent valve is to do a leak down test on each cylinder at 100 psi. It will tell you if you have a bent exhaust valve or a bent intake valve. It’ll also tell you how good your rings are sealing up. Leak down test is much better than compression test.
