Problem is it does not start.
What I checked and results:
points - gapped at .020 (this is where it was while running i did not change it)
Plug - new autolite 216
I have 12v at the coil in the start and run position
I have 12v at the VR where it should
took plug out connected to wire and held by bolt and no spark.....while cranking
The points and condenser, coil are all less than 6 months old.
While trying to start it, it finally had a HUGE LOUD backfire pop !! sounded like a gun shot.....
I think there is a possibility that I maybe left the key in the run position overnight and thats why the battery was dead? Could this toast the points?
it also has a brand new wireharness and there is no draw.
Help , snow is comming  |
If you inadvertently left the ignition on, it is also possible you got the points hot,
I would look to see that:
# 1 they are not burned and are still @ approx. .020 gap
# 2 insure that they are indeed making contact.
Then I would proceed with the checks that Roland mentioned.
I have seen times when leaving the ign. on, it does burn up the coil.
When cranking the engine without spark occurring @ the plug,
you are loading the engine/muffler with Gasoline.
Then when spark does occur intermittently, ka boom!!! like you describe
