Stihl MS250 - Ignition Coil Gap

pakalasa · 2013-06-13 07:49:11

I have an MS250 chainsaw. The earth cut-out wire broke, so saw wouln't stop. I took off the ignition coil thinking that was the problem. To put it back, I need to know the gap between the coil and the rotor magnets. I googled it, some say 0.2mm. Others 0.2 to 0.4mm. Anyone know what it should be?

Found this since. Seems to be 0.2mm alright.

Ended up using 2 strips of aluminium from a fanta can. Each 0.1mm, so stacked up to just a little over 0.2mm. Saw going great.
