Let me first cover what ive done....
1.Piston visually inspected good
2.150psi compression
3. Crankcase held vac and pressure fine.
4. Carb inspected and a new diaphragm installed, Carb pop tested good.
5. New fuel filter, oem line is a bit soft but held pressure.
6. Idle will hold as low as 1660rpms and do it as long as you like.
Now, what it is going. Fires up in 2 or 3 pulls from cold, idles strong. You rev it up and initially it feels fat, but if you hold it, it leans out and goes, in my opinion, too lean. My tach freaks out when I hook it up to this saw so i have little tach info. But the plug reads lighter than id like, if I go richer on the H needle, the initial bog feels fatter but the actual top speed seems unaffected. Eventually it gets to the point where it will no longer clean up..too rich, so I hold it wide open...and give the H needle a slight twist in and it takes off to that Lean high rev condition.
To be clear though, it doesn't run away...it feels like its hitting 13,500...its not wound up like an ms260 but its going above the 12,500 max speed.
Ive got a complete carb kit coming for it...and a new fuel line, but short of those im drawing a blank.
