Morning all,
Thought you guys might be able to help on this one. About a week ago, I decided to change the oil and adjust the valves on my '74. Last time I did the valves was over a year ago and they were starting to get noisy. In a nutshell here is how that morning went.
Drained oil
Removed valve cover
Turned over engine by bridging wires on Passenger Fender relay (here is where my problem might stem from) to adjust all valves.
Pulled plugs and checked compression which was 1-125, 2-130, 3-125, 4-125
NGK BPR6EGP - All plugs were a nice light-ish brown gray but #3 had a mineral deposit of sorts on it. I picked it off with my nail but it was hard stuff and thick.
Replaced Valve cover then oil then filter.
Keep in mind that other than noisy valves this car runs (ran) like a top and is a rocket for a stock engine (with a PECO). Never a burp never a hiccup - starts without choking even in winter.
I run a one of Jeff's 25D's with Pertronix. One of three I had him build for me. In fact I should send him two more.
Started it up and she ran quietly.
All is well until I drive it. I can barely take off from a stop without it sounding like it is running on 3-cyls. Bogging and sputtering but then it kicks in fine. At higher speeds it runs like a top again. I checked and replaced the #3 plug and it still runs rough and I when I did I noticed that all my plugs are black and sooty like it is running really rich. Tailpipe is also sooty and it was not before. I've driven it about 100 miles this way to see if I can blow out anything that might have changed as a result of my service.
My fear is did I partially damage the Pertronix by trying to turn over the engine using the relay? Should I look elsewhere and is using the relay this way a bad idea?
Should I check the valves again?
Cheers
Vince
