Here’s the scoop. Bought a Weber 45 DCOE on e-bay (Trying to keep up with B-racer).

Can’t seem to get it to run well at all. Car seems to missing running rough and no power. Switched back to my HIFs and car ran very well. Last evening I adjusted the valves and the car once again ran very well. On the freeway today running at about 75 mph in overdrive, the car just shut down. Pulled over to side of road and found out that there wasn’t any spark. Towed car home switched from Pertonix to points plenty of spark, but still won’t start. Pulled the plugs and cylinders 1 and 2 looked good, grayish/white. The plugs on three and four looked reddish. This is new. They were fine last evening but reddish tonight. Ran a compression check and all four cylinders were between 175 and 185. Could I have burned a valve? And if so, wouldn’t the car still start?

Sorry for the long ranting rave but I am stumped.

Thanks, Tom

You kind of jump around a lot. I would see if your getting fuel because you say your getting spark. You need both for it to run, sometimes you can put a little gas in a oil can and squirt it down the carbs just to see if it will start up. Never really heard of a red color on the spark plugs before, but wouldn't think it would indicate a burnt valve. You usually loose compression with a burnt valve.

You have just described a problem most of us here have.

We can't leave the SOB alone and just drive it!

Tinker tinker tinker.

What Joe Huffaker used to refer to as "tuning the horsepower they bought right out of the engine".

Mac, that's funny! Knowing Tom quite well, you may be on to something... :-)

Has anyone seen the red color on spark plugs? Is that just from fuel additives and running lean? I think his compression figures look good, so the problem is probably with fuel or spark. The engine still turns over steady and sound fine. It died like a light switch went off. My first thought was overflow tubes on the carbs plugged, then igniton failure.

Send me the DCOE when you get fed up with it.

Plenty of spark where? At the plugs or at the dist? Could be a bad rotor.

O.K. Here's the deal. I was just about ready to pull the cylinder head to take a look at the pistons. Thought I would look at the new distributor with the points one last time and it looked awfully bare! So I forgot the rotor cap! Put it in and varoom off she roared. A simple mistake that I once again over analyzed. Car runs great justwondering if I want to invest in another electronic ignition or stick with points. Tom
