I'm starting to wonder if I'll need to adj the carb because it may lean
things out a bit too much after all this? Any thoughts?
Nate,
I can't tell without an O2 sensor but I believe the coach was/is
running a bit lean from the gitgo anyway. On loooong grades I can
actually get more power and lower the engine temp a little by hitting
the electric fuel pump. So much for supply, the jetting, however, is
due for a change. Most likely up two jet sizes due to the crap-like
qualities of that wonderful oxygenated fuel here in CA. One of the best
Rochester carb guys in the business is here in San Diego and I had an
opportunity to talk with him Sunday. He pretty much summed up all I've
read here in the digest and then some. It's going to him soon.
HTH,
Steve F.
