Re: No go in drive.

My only caution against doing the doing the conventional "pull the wire off the plug" drop cylinder test to check spark on this motor is this. The weak point of these engines is the ignition system. This electronic ignition has a reputation of being quite prone to failure as compared to most others on the market. It is also NLA and used replacements are not that plentiful. Due to the reputation for fragility, I would be apprehensive about pulling a plug wire wire this engine is running for fear of damaging the ignition with It running and not having the plug wire grounded. A neon tester or a timing light will tell you the same thing without the need to run with one lead not grounded. A spark test should be performed with the engine running though. This will give some important information toward diagnosing the running problems.
