Right! I termed "fuel" jet as the one on the fuel inlet side-the other as "air" side incorrectly (trying to clarify only made matters worse)- When I adjusted the passenger side mixing screw, it changed rpms. Not so on the drivers' side. No change at all. What would this indicate? Also, if I were to change the metering jets(and rods), how would I determine which size is best? I can have this carb pulled apart in a matter of minutes, but surely with my luck, it couldn't be that simple. I'm very comfortable working on a carb, and follow the instructions to the letter, although I feel like I'm in a nail biting suspense movie, with malevolent twists and turns designed to intrigue and perplex the helpless victim. I can't help but feel the durn new metering components would cost as much as a new carb. All this stuff seems to be insanely over inflated, for the cheesy junk they actually are. ANYhoo, we're located in Texas City, just a sight down the road, as the crow flies from y'all.
