SC won't idle
 

I just purchased a 79 SC which has run fine until this morning. When I started it the idle would fluctuate from 1200 down to 600 rpm in about a six second cycle. It only died when I tried to engage the clutch. Once moving, it did the same thing at every stop. I went about two miles to the store. When I came out 20 minutes later it ran fine.

Just prior to my purchase it had the fuel pump relay, CD unit, ignition coil, and spark plugs replaced.

Suggestions?

RICH,

That sounds like a fuel pressure regulator problem. If the fuel pressure is to low during warm-up, it will make the engine run too rich untill you get some heat into the motor.

Good Luck,
