I bought my '80 Std this past June and had problems with #1 plug fouling in like 20 miles to the point where it was missing real bad. Compresssion is good. The plug was really sooty. I replaced the carb body and got a hugh improvement but still have an issue with that cylinder- instead of fouling sooty now the plug is turning shiny black and I am using some oil plus I'm getting some exhaust smoke so thanks to advise from y'all ( hey, I'm in Tennessee) it seems like I have either a stuck oil ring on the piston or a bad valve seal. I'm going to go after the valve seals- I've seen several posts about using rope, air, etc to keep the valves in place when you remove the keepers and springs. Does anybody know a source for a spring compressor that will work on a GL1100 head when it's still on the engine? While I have the cam off is there anything besides the seals I should do as a 'while it's apart might as well thing'? Timing belts are new or I'd do them as well. Thanks.
