My 1975 V$ 85HP Johnson runs great on Muffs and in a barrel of Water. Put it in the river? It won't start.
So far we have:
1. Changed the plugs
2. Set the Timing
3. Checked for Bad Ground
4. Checked Spark
5. Removed and Cleaned Carbs
6. Cleaned Stator Contacts
7. Checked Compression (125psi on all 4)
Problem remains unchanged. What else is there? Can Bad Exhaust Gaskets cause this by allowing back pressure to built up inside? When cranking the engine while in the river, no evidence of exhaust coming out of Prop is showing (no bubbles, no nothing), pull it out of the water, and place in barrel of water, (Prop exhausts as expected)
