Hi Doug. Have you ever noticed that some guys will post over and over until they resolve their problem and then abruptly stop updating. That hurts.
That being said, I want to post until I'm out of the woods with I-6 woes. As you know, it helps to describe perfectly and consider air, fuel, and ignition when looking into performance probs.
For starters, I believe I was over-attempting to fix my engine bugs by leaning it out. It seems my engine wanted a bit more fuel. Secondly, vacuum leaks have to be addressed or nothing will ever smooth out. MOST all vacuum gaskets, hoses, valves, grommets were checked and replaced as needed. I am also now set up with a paper air cleaner instead of oil bath system (jury still out on this trial).
My latest find is a very faint hiss behind the booster; heard only inside the cab near the push rod. It takes a hose to hear it. It may be a normal sound; but I'm digging as I write. A bad booster usually gets a louder hiss as you depress the pedal; mine does not. However, if I'm not suppose to hear anything at all, then I need to get it right if I'm to move forward intelligently. Am I right? The engine needs to breath exactly as designed. As evidence to this, I disconnected the check valve while the engine was running and the truck stalled out. Hope this helps others.
