RE: Carb jetting help!

Modern gas tends not to color the plugs as much as it did way back when, unless your running really, really rich, try looking at the ground electrode, you should be able to see where it gets hot, will be a bluish color and then fade back to the color of the plug shell, usually little more than halfway away from the end seems to be about right, (from what I've read and used, it's the only way I was able to use to get my boat jetted correctly), what's your vaccum at idle? I know others wont agree but I usually remove those secondary power valves and block with a plug and up the secondary jets 6-8 sizes and go from there.

This thread, so far...
