200s Fresh Bore, Smoking Quite a Bit??
Just rebuilt my 200s. Was bored over, new piston +rings obviously. Also did the valve seals. Just got it back running a little bit ago. Started it up, and other than it running a little rough, probably carb adjustments, all was good, until about 4-5 minutes in when it started smoking pretty good. After I completely filled my garage with smoke, I shut it down for a few minutes. I started it back up, and same thing, started smoking again after a few minutes. Its been a while since I did a bore but I don't ever remember this. I have had it running about a total of 25 minutes and its still smoking. Plug is carbon fouled but not wet. Do the rings need more time to set, or do I have other issues here?
