HI all, It seems no matter what I do my TR6 runs rich throughout all rpm ranges as verified by colortune and by the color of the spark plugs. I have them set 3 turns counterclockwise now. I have set valves, a newly rebuilt dizzy, proper dwell/timing, new proper plugs, distributor cap, wires, coil, etc. through the ignition. For the carbs, I have verified the float level, diaphrams have no holes I can detect, and have replaced both air bypass valve diaphrams and set them per Joe Curto to keep the diaphragm "piston" shut. Te only thing odd is I have noticed that if I pull the hose on the top of the carbon canister, the RPMs jump up, which has been cited as a cause to always run rich https://www.bmcno.org/tech tips/zenith stromberg tech tips.htm Before I buy a new carbon canister, is there a way to test it? Any other thoughts? I have a manual choke and no anti run on valve.
