Good morning everyone. I have a Big Red 28 on my MGT 4.6. The motor has been sealed and has 1 gallon or a little more through it. The problem I am having is the engine will not accelerate past have throttle when I try to lean the motor pass factory settings. The motor idles fine. I can't get the temp past 180F. I have never had a motor do this. I took the motor apart and cleaned and sealed it. Put a new glow plug and fuel line on it with no change. Any help would be appreciated.
