I've been having trouble with my poly running rough at idle. At higher RPMs it's been running just fine, though. After looking at the plugs and other basics, I replaced the fuel filter - just in case a chunk of crud got caught in it. I put a see-thru filter on it this time, and it ran really fine until I got it up to temperaure. Then the intermittent missing came back. This time I'm getting more of a bog at speed with harder acceleration, but better running at low end rpms. While undr the hood, I noticed that at times fuel seems to be just trickling into the filter - to the point of the filter having just a bit in it below the element. Other times the level of fuel is over the top of the element - which looks more like
it should. So I'm thinking the electric fuel pump may be starting to take a dump on me. This got me thinking - if I do end up having to replace it, why not put a mechanical pump back on? I'm interested in the group's opinions on mechanical vs electric fuel pumps on a stock Poly. By the way, I haven't eliminated the coil as the possible culpret to my problems, either, but the fuel flow running through the filter doesn't look adequate to me regardless.
Thanks,
Dave
