when they work well, it is nothing short of amazing.
When they don't it is.... amazing....
Okay gentlemen. I need to figure out what to do here. I have this mint 2171 Jred that I ran 3/4 of a tank outta today. The engine runs really well, compression is excellent. When the carb is wiling to provide the correct mixture it is amazing! Started out pretty good. adjust the L a touch leaner for the lofty elevation I am at, and dial the H in to something around 12,500. Tossing chips... really well. 20 minutes later and something ain't right. Adjust it a bit? Didn't help. It goes into a "bog mode" RPM refuses to climb above about 7000 and power is way way down. The sound of the engine is like it is 4 stroking... missing quite frequently. On the next cut, it might wind up normal, or run in the bog mode. roll of the dice.
I was just thinking here, while typing this out. Could this be a ignition problem? And not a carb problem??
How would I check it out?
Come to think about it... when it went into "bog mode" it was not dumping a ton of smoke... that might imply a igniton problem. Now the next question, would be.... spark plug? Coil? Muffler bearings??
Thanks in advance. The saw is a real joy to run, smooth and responsive when it is willing to cooperate.
