Some updates :

- glow plug is good, changed it anyway for good measure.
- adjusted (again) HS valve back to factory settings, about 2 1/4 - 2 1/2 turns out.
- found LS valve adjustment info (quite confusing). may or may not be at factory settings. It said open up the carb, close then open 2 - 2 1/2 turns. think i got it
- disconnect hose from muffler and blow to prime .. almost positive no leak.
- disconnect hose off carb, blow and smooth flow.. seems ok.
- connect back to the carb, disconnect from HS valve .. blow to get fuel into carb but it seems very difficult to flow into carb. Maybe some dirt, old gukked up fuel or something inside. I tried getting some WD40 in there.

I'm pretty sure it's either the carb LS jet or some dirt / crap in the carb. Next step I guess remove carb and clean.

damn .....
