How Do You Find a Short?

[Rev]

Glad I was at least some help. I'm really only a fellow hobbiest. Now to the the new problem. If you have a vacuum leak, it can really only be iin some few places:

1.) hoses

2.) carburetor/manifold

3.) Manifold/ head

Check carefully in all those areas using spray on carburetor cleaner at idle around those potential leaks. If the idle improves when spraying , then you may have found the air leak.

The most difficult leak to find is at the intake / lifter valley gasket interface. If an air leak is indicated and no other place can be found, then you may need to pull the intake and look there (last resort).
