Ahoy...and thanx ahead of time to read and offer help.
I have a 1978 Johnson 75 HP Stinger.
Starts and runs great...out of water.
Using muffs..runs and idles like an old Hamilton Service Watch.
Gear linkage disconnected...in tank..nice throttle up.
Link and synch proceedure...new gas. Seafoam. New plugs...cleaned carbs.
Compression is between 120 and 128 between 1st and 3rd cylinders.
No fuel puking but heavy consumption.
On the water...starts...idles...warms up....put it in gear...throttle up and it stutters and dies.
Any help would be graciously appreciated.
