Well.... it sounds like more fuel isn't the issue. Granted you could drown a carb but a drizzle wouldn't do that. You could still have fuel issues down the road, but if the butterflies are working and you bottle feed it, it should rev up. Takes more gas then you would think full throttle btw.

So... Have you done a compression check? Plug wires in the right order? Guess it could be a bad condenser at this point also... are these tests in the garage only?.


Start with the free/cheap checks. Plugwires, compression check, condenser.


Everything needs to work in concert. One thing bad and it makes everything "sound" bad. If everything is on it's so sweet.

I had an issue like this with my 38 after it was rebuild. In the garage it would purr at idle and rev. Once I drove it underload it fell on it's face. Turned out to be sticky valves.
