125 Force Cold running rough

[gregworkman]

I have 1986 125 Force 2 stroke and starts and runs fine but when I full throttle it, it only runs about 1/2 power for 1st 5-10 minutes then out of nowhere it gives me full power and is good the rest of the day. Kind of like fuel is pluged up then is set free.... maybe a hose???? Plugs are good, no leaks, filter looks fine. Am going to try SeaFoam, but does anyone know what this typically would or could be? Very inconsistant. Thank you very much

1. Go to the FAQ at the beginning of the maintenance section of the forums and look for the decarbing procedure.

2. Look at your intake covers and see if they have small rubber hoses going to the manifold or block. This is the engine fuel recirculation system and it gets plugged up. You need to clean it out.
