Hi all. This motor has very low hours on it since new. I am having problems with it idles fine, but has now high rpms or power under throttle.
Awhile back, it got water in the gas that jelled up in the 4 carbs. I have since cleaned the carbs twice, replaced fuel lines, bulb and portable tank. I had a boat guy replace the diaphragm in the fuel pump, which had a hole or rip in it. I have also tried the squeeze bulb test under throttle and it does not change anything.
It used to just try to rev and die when you hit the gas and then hard to start. Now it just runs slowly at wot.
I will check the compression. Re testing ignition components, do you need to remove the flywheel and how difficult is this?
Any input is appreciated. Could it still be the fuel pump?
