PV's are clean.
Today I went out and started it..was about 30 deg out..
choke on full, pulled and pulled on it.. the 15th pull it made it's fisrt fire.. 16th ALMOST ran, 17th.. started running.
Has new plugs in it. Left it sitting there for about 30 seconds then idle (was 1800'ish RPM) started to drop to about 1100.. moved choke to half way. Idle came up a bit to about 1600. Ran for about another 30 seconds, engine got rough and idle dropped down to <1000. Center plug got fouled.
Carbs? Cold start procedure? Weak spark? Moon and planets not aligned properly?
