Hello, just wanted to ask for someones opinnion of this situation. The
motor will not idle well. It seems to surge. Idles and then misses and
idles again and then dies. I changed the points and no better. I am
wondering if it could be the coil. I have ordered a carb kit, but the
surge thing sounds electrical. Any thoughts. Thanks
No need to guess.
1) Compression test each cylinder - if one is more than 10% down on
the rest, that's a problem.
2) Ignition test with an adjustable gap - big blue spark needed at
each lead.
3) Fuel pressure test at carb - steady reading.
4) inlet manifold vacuum reading.
It doesn't cost a fortune to make these tests.
But they may save you a fortune.
