OK Lacking a little brother/sister/idiot close enough to get to hold the high tension lead, and having used my finger as a test probe far too many times to do it again (once is enough). :eek::00000061:

I invested in one of these:


It has been rattling around in the tool box for decades now and sees frequent use on SGEs (small gas engines). The price seems to have kept pace with inflation since I purchased the tester. :fing20:

There are several sources, with the ones from Horrible Fright being popular as they are cheap and effective.

Rog is right. I got that tool at O'Reilly's Auto Parts for a bit less than $10.00.

FERGUSONTO35; stoped at my friendly o'reilly's parts store and picked up one,about $7. now I have no spark.Points look god after I cleaned them and gaped(.015) them. Now what is every bodys guess? A $30 condenser or a $90 coil or both...The saw has good compression and ran fine and started good last time it was ran.

OK, with that bit of info I might suggest you try disconnecting the kill switch and leave the wire open (Non grounded state) and see if you have spark. The grounding toggles have been known to short to ground and stay that way. I have found the replacement switches at my local hardware store in a switch display. The last one I bought was about $6.

The reason I say this is because the saw ran well during the last operation so I doubt if the coil or condenser had a catastrophic failure in storage. You might also want to check the continuity of the wires as a break in the lead from the coil to the points could also cause a sudden loss of ignition.

A VOM is also a mighty handy piece of kit in the tool box.

Thanks rog. I have disconnected the switch, but it had continuity in the off position but had none when in the on position. So I think the switch is good. Will check the leads to the points tomorrow. Pull the da%%%% flywheel again!!!! By the way has anyone had any experience with "cheap chainsaw parts out of Washington state or Randy's engine repair out of Virgina???

on that old xl12 i have 2 of them the first thing I'd check is the points and condenser mack sure the points are clean they like to corrode a bit and then after checking that check the gap on the coil it should be about .010 a bussiness card between the magnet on the flywheel and the coil makes a great gapping tool
