after replacing the plugs and using auto choke setting i was able to run it for 10 minutes uin the barrell. quit a couple of times but restarted immediately. finally ran w/o choke after quite a while. dosen't seem to run hot but idle seems a little rough. can't find any high speed adjustment but tweaked the two slo speed dials and helped a little. this is great progress to me considering the motor was frozen up three weeks ago. a healthy dose of pb blaster in each cylinder fo a week did the job. tough getting it out of the crankcase, though. had to crank it w/o plugs for many times and i think even today there was still a little left to foul the plugs. should be all burnt off by now. thanks to the one guy who responded and i hope this helps somebody. any tips on fine tuning be fore i rebuild the carburator greatly appreciated.
