I'm back, this time with no power. Engine starts and idles pretty well, it just doesn't go anywhere very well. As soon as you let off the clutch, it bogs down and struggles. I get a cough from the carbs every once and a while, and a slow, rough acceleration. Strap yourselves in, because this is kind of long winded. My apologies. I know it sounds like a timing issue, but it was kind of all of the sudden.
Here's what I've done already to no avail:
Assumed it was in the ignition, replaced points and condenser with Pertronix,
rotor is less than a year old, maybe 30 miles on it.
Checked timing, it was pretty far advanced, retarded it to what I think was about 6 degrees BTDC, no change. It acts the same way in both positions, and everywhere in between, but it does idle a little smoother when advanced. I have suspicions that the PO upgraded the cam because I found one in the box of parts. Maybe this is why it likes the advance?
One thing though, I did get a shock from the dizzy cap when adjusting. I have a new dizzy cap and plug wires on order. The old one appears to be fine (other than the shock) and the plug wires are less than a year old.
Replaced spark plugs. The old ones were a little carbonized from my hot start/flooding issues I had before. No help.
Adjusted carb floats on the dual Zeniths. Just bent the tab a little (very little) to lower the float level because I was getting flooding problems upon starting before. I'm getting the feeling that it was an ignition problem, not a fuel problem. (I'm hoping the Pertronix remedies that) I'm thinking of pulling the tops off the carbs again and checking everything out. My fear is that I've done this about 3 times and that maybe the gasket isn't sealing well after all the on and off. I'm yet to check fuel pressure.
Adjusted mix screws on carbs, they're both about 1 1/2 turns out right now. No real change in power issues.
Vacuum leak?
Clogged Exhaust?
Any input would be much appreciated. Thanks in advance.
