Greetings to all from the newbie!
OK, So here is my problem, but first, let me give some basics.
I took my 1986 Johnson 60hp into the shop to get the carbs rebuilt. The problem I was having with the motor is that the motor would not idle. In addition, when you gave it gas, you would have to "choke" the motor to get it to get on plane. After you got the motor on plane, it ran fine.
In addition, When I would troll with the boat, at first, the motor would start to "bog down" when you were trolling and for the first 5 minutes or so of trolling, you would have to "choke" the motor to keep it running.
I assumed this was a carb problem thinking I had a leak in a gasket or something like that.
My mechanic rebuilt my cards. It now idles fine BUT, when you try to give it gas, it totally bogs down and he was choking the carbs to get it to get on plane again. He replaced all my carbs with carbs from another 60hp Johnson and the same thing happened.
He checked the fuel pump and there is more than sufficient pressure coming from the fuel pump.
He checked the reed valves and everything is fine.
He replaced the head gasket.
He drained my gas tank and replaced it with new gas and blew out all the lines. He even used his own portable tank with gas and still the same thing happened.
He is under the assumption that now, it is an internal problem as in the motor is not creating enough internal pressure to pull enough gas into the cylinder to create enough power to run the engine when it is under heavy presssure.
Is his assumption accurate and how much is this going to cost me (for example, is this an engine rebuild?) or is there some thing we are missing?
He probably has done other things and if you think of something I may have not mentioned that he performed, ask and I will tell...
