Engine wont start.

[Oldgearz]

Don't mean to start an argument about whether condensers need to be grounded, but I've found in my old 6 volt tractors that have a condenser screwed to the top plate, sometimes a patina will develop on the top plate that prevents the condenser from grounding. Typical symptoms of this are hard starting, misfires and especially backfires. Sand the plate where the condenser mounts and presto it's fixed.
