Howdy Folks,
I had two 025 that I was working on today. !st was clean sharpen and adjust, cut a few pieces, good saw. 2nd one was my brother's, he said it would run for a while then would not restart. I had already replaced the feul line because I could see the cracks in it and the impulse line (old one was good after I got to it but replaced it anyway) and both diaphrams in the carb. I did all the normal maintenance stuff on it, dress bar, sharpened chain, cleaned air filter, new plug and did a good cleaning on the saw.
It would start and I let her warm up and she didn't sound right and wouldn't idle right. I was chasing the idle but just couldn't catch it so I shut her down and seated the L screw and backed her out one turn. I go to restart and she wouldn't fire. Plug was wet but no spark. Took it back to trailer/shop and busted out the multi meter. Measured resistance from plug wire to short circuit terminal on coil and it reads 6.5Kohms, measured from short circuit terminal to ground and it reads 5.7Kohms.
I pulled the cover off the other (good/working) 025 and measure resistance from plug wire to short circuit terminal it reads 10.7Kohms, measured from short circuit terminal to ground and it reads 1.6 ohms.
So I believe the coil is bad. Before I tell him to take it to the dealer is there anything I'm missing? It may be under warranty so I don't want to pull the plug wire out or mess up anything (afraid the dealer might tell him he won't cover it because you monkeyed with it). I will only do nondestructive type stuff for the moment. I do want to see if I/he can keep the old coil so I can take it apart and see whats in there.
Have a good evening all.
