OK, I know this type of topic has been covered, but I have searched the forum, and have not quite found my answer.
Problem:
I have just rebuilt my F engine, new rings, valves done, etc. Compression is now good, and all the leaks appear fixed. I still run stock points in a NON-USA dizzy, and have a NON-USA Aisin carb. I have set the valve clearances to spec when warm. The problem is that when the engine runs at about 1500 - 2500rpm, there is a terrible misfire, more noticable when the engine is not loaded, going up a hill it gets better when you apply more gas.
There is a hesistation when pulling away from a stop sign. I cannot pull away from idle, the engine dies, I first have to get the engine above 1500 and then let out the clutch.
My queries:
Ignition system is newish, but tends to burn the points quite quickly. I will be checking the dwell angle on the weekend, but my question is, apart from the point gap, how else would one adjust the dwell angle? I have repeatedly set the timing, but the points keep burning after 1000 miles. What should the dwell be, 41 ? At what engine rpm should one check the timing, the figure varies from 650 - 950 depending on which forum you look ???
If I look down the carb while applying the gas, the accelerator pump jet appears to be working, as a seemingly healthy dose of fuel is pumped into the manifold. When adjusting the idle mixture screw, it appears to have no affect on the engine. Could this problem be with the carb? I am at sea level, what are the correct jets to use?
I have put new manifold gaskets on, and there does not appear to be any leaks. I can't feel any significant play on the dizzy shaft either.
Anyone got some answers :'(
