Starts right up,but when I take off the plug wire at the distrib for the left side nothing changes,when I unplug the right plug at the distrib she dies. What am I missing? Any help will be greatly appreciated, Thanks [Reply]   [No Email]

You have a dual throat carb, one for each cylinder. I've experienced something similar..carb needed cleaning/rebuilding. [Reply]  [No Email]

All new electrics, but only running on one cylinder. Checked the mechanical and found a spring was broken on the intake valve. [Reply]  [No Email]

Valve adjustment couldn't hurt either. Can you get any change by adjusting the carb. idle needles ? [Reply]  [No Email]

After much head scratching I found the valve lash backed away on a valve. Probably isn't the problem in your case but it's a possibility. Jim [Reply]  [No Email]
