=====================

If you were looking for screen clogged, does that mean you're only
having high-speed misfire, because luel filter or plugged screen would
only show up at high load / speed.

Whether it's missing at low speed or high speed, I'd run a can of
Techron Injector cleaner through it, or at least a couple tanks of
gasohol, but then I always try the cheapest fixes first.

Does it ever show signs of FLOODED engine first thing in the morning?
