Ok, since you guys did so well with the STRUNK chainsaw thing, I figured I'd give you crack at another problem I've been having.
I've got a Craftsman 16" chainsaw that dies when you really get into some heavy cutting (read that, you run it at full bore under load for an extended time). When you try to re-start it, it just won't. Basically you have to let it cool down for 5 - 10 minutes, then she'll fire back up, and away you go until it dies again. However, it will start and run fine if you are just cutting light stuff.
Now for some other pertinent info:
I'm running 40:1 mix, as suggested by the manufacturer, and the mix is brand new (new gas, new oil).
The plug is new, and not fouled.
The ignition module is new.
The low speed jet is set approx. 1.25 turns out from full in, and it idles fine most of the time.. however sometimes it will die when idling, but will restart with no problems.
The high speed jet is set so that it is just a little rich at wide open (i.e. the motor goes from that high whine to a little grumbly)
The fuel line is not mushy, and the in-line fuel filter is not plugged, so the carb should be getting no shortage of fuel.
The fuel tank cap is brand new.
Lastly, I'm pretty handy with motors (was actually a small engine mechanic during my college years), and after tearing apart the carb, and finding nothing, I'm stumped (no pun intended ) The only thing I haven't checked is the exhaust for carbon build up.. and I intend to do that the next chance I get.
So, if you've seen this before, and can point me in the right direction.. I'm all ears!
Thanks in advance!
