CondenserPossibilities I can think of:
Intermittent fuel pump problem
Residual bad fuel in tank
Crud from tank now clogging carb passages
Coil getting hot, then cooling off
A few observations, and things I (think I) know so far:
and some of them only lead to more questions.
-The KT17 shroud and air filter claim to be Series 2.
-The Spec. is 24302, but is that just the shroud, or actually the engine?
-There is no oil filter.
-One cylinder is slightly egg-shaped, but it has a std piston, and valve clearances of 6 and 11.
-There seems to be an oil leak at a case joint that does not look like fun to correct.
-The hydraulic lift valve may be frozen. It looks like a P.O. may have tried too hard to move the lever, and forced it out of one end of its mount, leading me to think the valve did not cooperate.
-The fender pan has an IH label on it, not a CCC...does the serial number back that up?
-I.D. tags are easier to decipher when they are not monochromatic:
