The engine does not start after winter storage. No spark at any cylinder. The engine cracks and the battery is new and full!
Kill switch tested! Remote at neutral e.t.c
The story is that the engine could not start with no spark after winter storage. One day I tried again and it started and run for 15 minutes.
After that day it does the same. It does not start with no spark in any cylinder.
Any Help will be appreciated!
 
Test the ignition system according to the Johnson service manual. Or ask a dealer to do this, it is a quite simple test (with the correct equipment).
 
disconnect the kill switch under the cowl.....there is a green and black wire coming off your power pack with an inline connection.....check the small 2 wire plug from the trigger to the power pack for a pushed back pin....they will run making a tip to tip connection instead of being fully connected and then all of a sudden go dead...you may have to disconnect it and turn the plug from the trigger sideways to see a pushed back pin...make sure you have a good ground on the engine... i would use an inductive timing light for a start to make sure it was a fire problem...how old is the gas?...you checked it for lack of fire at the start of the problem....after you got it to run and it then failed did you check it again to see if it is still a fire problem?
