Thor's Hammer
Wolfish. Sometimes Bites.
Decided to pull out an MS200 thats been sitting at the back of the bench broken with a split inlet boot, and make it work again. I dont like having broken saws.
So it didnt take long to fix, new inlet boot in place, and put back together. Except now it has a really irritating fault.
Before I changed the boot, it ran fine, apart from fast revving and a bit of lean fast running at certain saw angles.
Went to start the saw and it started fine. Revved up, ticked over etc. Then suddenly just stopped. Pull pull pull, nothing doing, wont start. Check fuel lines etc, no luck. Pour teaspoon of fuel into carb, still wont start. Pulled the plug, then plugged it in the lead wile out to check for spark. First few pulls, nothing.... then a nice fat spark.
Re- install plug, and saw starts straight away. 2 minutes later, cuts out all over again. repeat twice. Is it possible that a coil will show spark in open air but not under compression?
