OK car has been running like a top --near perfect so what do I do--take fuel system all apart to clean out as she was going to sit for a month--did my same routine blow out , WD40 then blow-- alls well.
Fueled up out of my sealed drum --accidentally added too much top lube but figured what the heck
Got to track, fired up and she was burning my eyes--never does that and it was a off but.....get in the water and she falls flat on her face no power just weird--get back to the pits and my dumb self had main bypass in backwards--OK swapped it around --sure sounds better--go back up and she was still flat--fell on her face--limped down--loaded up came home so..
Today--new plugs --old ones slightly fouled and couple were just black--fresh fuel out of same drum NO top lube--she lights right off runs and sounds normal--Whew!!
So was it the plugs second time ?? Or plugs and fuel with too much top lube?? What happened?
Rookie needs schooling Thanks in advance!

I have not had issues using top lube in my car, I use one container to a 55 gallon drum. Sometimes I don't have a bottle of lube to put in the new drum so I will run the weekend without lube than once it arrives I just dump it in the drum usually 20 gallons less fuel in the drum. What was the DA at Salt Lake compared to your normal?

If having to guess I would say combination.Too much fuel,too ,much lube that probably killed a plug of two.I have had plugs that look good that would not run and once swapped for new set was back to normal.One rerason I always put one new plug per side and work backwards.max of 4 runs on plugs and I always have a new one to read and can keep check on cylinder to cylinder burn.Used plugs go into warmup set and I rotate them out same way.Cost in minimal compared to loosing cpl runs or whole weekend.

Thanks
I tend to agree after going through it all--the plugs had been in for about 4 weekends and so after they were fouled --some pitiful-some looked ok--- but she sounded crisp with new ones

Have never used the stuff in my entire 40 years of racing so I have no answer for your issue
-
fresh plugs after the initial screw up solved the problem
thanks for helping

With the risk of being called cheap (or old school), I'll ask:
Any chance that a quick filing could revive those plugs? (restoring spark and enabling it to reach self-cleaning temperature again)
-
we use to glass bead our spark plugs to clean them and give us a second go around at reading plugs
-
The NGK's I have been using --I get from Ebay for about $20 delivered--they have been lasting a long time but I am guessing my screw up with the main bypass ruined this set--I am so glad that all it took was fresh set of plugs to fix my issue
I am guessing that my helper added a double dose of top lube looking at the bottle--I was just panicked over the wk end--lost an outing at the track --relieved to be back to normal--should have popped a new set in at the track but just got flustered--I have never had to work on a car at the track in almost 30 years of racing--always took lot of pride in that fact --so a little screw up just clobbered me
Thanks for all the comments and help!

In your defense, I'll quote what a college girlfriend used to tell me: "extra lube won't hurt!" ::)

You can use a propane torch to clean up spark plugs. Heat it up until it stops smoking and turns a little red and there clean. Just never had to do it for my racecar.

I don't use top lube. I change 1 & 6 plugs before the start of a new day/race. NGK have been consistent in the burn on the ground strap. I tune by the looks of those 2 cylinders and a thermocouple in # 6 cylinder. I am in a sweet spot and haven't changed the tune-up for several races.
