Hi Guys,

mjfrederick, I'm guessing you didn't pick up my goof in my earlier posting, it gets a bit late for me at times, but what I said about the reg screw bieng about 1 turn in is right,
and this past w/end I have found that some of these 170's after about 100 runs or so require the req to be adjusted back out again as they start to load up
and quit.
The big screw that we adjust is actually regulating the pressure from the crankcase, which in turn controlls the flow of fuel from the pump,
so it is a regulator and the pump is inside the housing, so every one is right on what they call it.
