I've just fouled 2 out of 4 plugs for the third time in about 3 weeks. This only 10 days after I got the car back from the mechanic.
Disclaimers applying being that the engine is very shortly going to be swapped for a new one, for reasons of needing a valve job, burning tons of oil, and lots of blowby.
I'm running dual 40 DCOES, just professionally synched and adjusted. Also a MDS 6a triggered by a stock distrib running to a bosch red coil.
The car idles now smoothly at 1.3k, it doesn't idle smoothly at all under 1k. Er, it does when it has clean plugs anyhow.
I am in Charleston, which is extremely hot and humid this time of year. I also park dowtown in a parking garage only 1.5 miles from my house, so my commutes are too short to even get the car completely warm, usually. On the days when I have to run all the way up to the top 8th floor of the deck, I find myself apologizing profusely to the car, as I cant help but feel badly about using those 4 synchronized barrels to inch up through the traffic of the garage.
Im concerned about running too lean if i start playing with the idle screws. I understand fouling is caused by too rich, but how do you tell if you are going too lean?
Any help appreciated.
