Thread: Test #1 Answers

#1 Broken woodruff key. Retarded timing from the flywheel slipping. Fix: New woodruff key and some blue loctite.

#2 Weak Coil. Resistance from the spark plug killed the spark. Fix New coil.

#3 Bad Bearings. Caused the flywheel to walk into the coil, grounding it out. Fix: New bearings and seals.

Let me know if you guys like this and I will do more of these.

#2 so a spark tester has less resistance than a plug? if you just grounded the plug to the cyl and had no spark.....then got spark with the spark tester. bad coil.


great idea for threads dean.......thanks

Yes the spark tester has less resistance. I have seen this happen now on 3 sepperate ocassions. The first time it took me 4 hours to figure it out
