Sorry for the delay, and thanks for the responses. My father had a medical emergency and I had to leave town.

I agree on the comp and leak down test. Those should have been performed first. I am looking around for the proper tools in the case that I do fly out to see the car.

--Valve adjustment has been recently performed, if I go out I will check it.
--Fuel filters have been replaced
--2 new injectors but no purge, I may do one depending on what I find
-- Mechanic replaced the prechamber on #1 and it made no difference
--I don't know about the nailing and have hazy information, but cracking the fuel line on # 1 prior to prechamber, quieted the engine. Either my brother or the mechanic said it reduced nailing.


I will aim at getting a good video and some photos, but it will be a while since I am out of town.
