Starts Ok but won't always idle for long or at all - runs rough at high idle-- pulled plug wires one at a time & found the top right cylinder not hitting- runs just as good with plug wire off. Swaped wires, plugs & coils & still the same--Spark is the same & all plugs look the same--All 4 cyl have a even 100 lbs compression----What the heck :blue:

Squirt some fuel in the throat of the carb of the cyl that isn't firing and see what happens.

OK, spraying fuel into top carb same side as non firing cyl makes it rev higher-
