So I have this Super 250 with a Tillotson HL-63G carb...Was my Dad's saw before he gave it up.
The saw will run and cut, will idle and rev all day when level and not under load....but:
The saw will run and cut, will idle and rev all day when level and not under load....but:
- Saw for a while (4-5 12" cuts) and it will quit....won't re-start till it cools off. Smokes a little while pulling (insert heart attack here) but won't start.
- Tip the saw forward from level while idling, it will quit after a bit.
- Leave it sit over a couple of days...it's hydro locked..have to remove the plug and dry out the cylinder before I can pull it.
- Till it warms up some, fuel leaks from somewhere and puts a good layer in the bottom of the air box. (Can't see where it's coming from). Gaskets around the fuel pump area seem wet though.
- Removed H and L needles and replaced mashed rubber something or other with small o-rings.
- Removed welch plug on inside and blew air through all ports (needles, seats, etc..removed)
- Replaced the old non-forked inlet control lever with a forked one, along with new needle and seat. (adjusted lever flush)
- Checked, cleaned fuel filter.
- Replaced all gaskets and fuel pump diaphragm.
- I think my next goal is to find out where the fuel is leaking from (maybe the inlet valve fulcrum which screws in from outside?)
- Maybe take the fuel tank apart and check for cracks in the fuel hose?
