Oh yah Iv had plenty of faulty new parts, I had just assumed that it was good cuas the engine had been running sooo good just a few days before.
I like the idea of a weak spark, boy wouldent that be an easy fix!!!

60 somthing degries outside right now, fired right up engine turned over maby 360* but fired right up.
havent tryed messing with the ignition yet, gunna warm it up and retorque the heads and do a compression test first.
then onto playin with the ignition if that dont do it!!!

Pulled my compression test just to eliminate that. my compression tester goes up in 20 psi incriments so I had to do some guestimating on some of them, but they were all in the same place on the guage
#1-138 psi
#2-140 psi
#3-140 psi
#4-140 psi
#5-138 psi
#6-180 psi
#7-142 psi
#8-138 psi

All spark plugs came out practially golden... so I guess Im down to waiting for a cold day so I can start tracing down my eletrical problem... unless somebody has better sugestions

So 180 - 27 = 153 PSI. In reality 138 is low and 138 + 21 = 159 PSI. I would suspect coolant leak or oil leak into $6. Try running another compression check after squirting a 1/2 teaspoon of oil in the cylinders.
