I have a 1990 50HP (507X90A) Force Outboard motor which is backfiring.
Problem: Will not start, as it is now backfiring. The engine ran last year for a brief 10 seconds without a backfire, then quit.
The following have been completed to date:

The following have been completed to date:
- New stator ? wires connected in the right places ? no more misfire (it is a fixed/set alignment)
- Replaced the CDI Module ? recently bought second hand which is one year old from the original owner.
- Good compression in both plugs
- Reeds are shiny clean and not sticking
- New spark plugs?not fowled. (tested ? good spark with the meter)
- Fresh gas & oil, new gas treatment (emptied old gas from bowl)
- Starter works & turns crankshaft.
- Verified all the wiring according to the wiring diagram ? no breaks
- New rectifiers ? both work
- Any suggestions?
