Fleetwin,
I put a rebuild kit into the fuel pump and will replace all of the rubber fuel line pieces. I’m waiting on a replacement high speed jet before it all goes back together again. I will rig up something to test the individual cylinders response to the selinoid choke injection as you suggested. Your appraisal of a fuel issue feels correct. It starts, runs and idles as it always had. I will try the spare fuel tank and if there is a reocurance, try the hose bulb primer. I hope it’s got nothing to do with the reed valves as they don’t seem to be available anymore.
