OK, time to embarrass myself with the bone headed move of the year. I got the interior in my R2 Hawk and decided it was time for a test drive to the gas station to check out the new engine. I got half way up the hill and thought I started to run out of gas and limped home. I added a few gallons and saw no improvement. I thought maybe the carb was crapped up with some rust from the tank and pulled the carb only to find it cleans as a whistle. I rigged up a fuel pressure gage and only had 2 PSI now and then, sometime nothing.
Has to be the fuel pump, right ? Take the pump off, it looks great too, but I'd better swap it. While swapping the fittings, I found the problem. I'd grabbed a PCV out of my brass drawer by mistake.
