OK, I've been having problems with with my 1977 85 hp Johnson.. running lean. Got a manual and I rebuilt the carbs installed new plugs and de-carbed the motor...was going to do a link and synch and having problems now and cant do one until I get these 2 other problems fixed...
1) The engine will turn over but will not start....I can spray some deep creep into the cylinders and it fires right up and runs... and it will rest if the day.. but I can let it sit over night it will not start.. as soon as I spray a squirt of deep creep it fires and runs. all fuel hoses are new the primer bulb works and the fuel pump is working. a good constant stream, the carbs are getting fuel and its not leaking out of the bowls of the carbs. its like the gas isn't getting back into the cylinders.
. next problem discovered when I tried to see if I had enough spark into spark plugs to ignite the fuel in the cylinders.
2) When looking at the back of the motor the bottom starboard cylinder is not getting any spark, all the other 3 has good blue spark and jumps a 1/4 inch. I can pull the spark plug wire off when it's running and it doesnt change the pitch of the motor but the other 3 will.
