Hi guys,
My 115 was taken to the dealer to have carbs cleaned and rebuilt as they were leaking out fuel causing a nice sheen on the water. They also replaced my fuel lines on the engine and replaced the throttle cables for me and did a tune up and said come get it, it was running great!
So, that was done, but now the motor does not seem to want to reach full power unless I push the key/choke and even at lower speeds it will smooth out RPM and sound when giving it the choke. At full power, I gain a couple hundred RPM and have to choke it to get the hole shot up on a plane. At idle speed, I must blip the choke every few moments to keep engine running smoothly and sometimes at all, and if just sitting there warming up it does make a weird sneeze sound or backfire from time to time after its been at idle for a while. The dealer mechanic said bring it back, but they said it is running fine. Maybe for them I guess if it starts and revs, that means it runs great. In the water, its a bit of a dog without that choke button.
I took the carbs off myself and I thought they looked clean, but used a can of cleaner and sprayed through every little hole and drilling I could see. Made no difference. I rebuilt the fuel pump since that seemed the likely problem, no help. I replaced the little O-rings and plastic parts on the fuel choke solenoid thinking it was somehow sucking air there, but that didn't work either.
My fuel is mixed at 50-1 and is clean. I have all new fuel lines, primer bulb, fuel filter, new fuel pump diaphragm and seals, a clean screen.... I mean it is strange that it will start up and rev up like mad, but under load, does not really want to give me 100% of what it has. It was running all out before I took it in for a carb rebuild to stop the leaking. I know I am missing something, any help would be greatly appreciated. Thank in advance for taking time to read all this, Greg
