Toro 283L- Losing power

Toro 283L with 700 hours. I am the original owner.

When the fan turns on it almost kills the motor. Seems to get better after it's been running long enough to get hot.

Earlier this Spring (It was 80 in March around here.) it didn't have enough power to pull itself up an incline and mow at the same time. I have tried new air filter, new plugs. For a while it seemed better. Today I had about half the yard done before it seemed to kick into full power. I mow a little over 8 acres. As an added symptom I have thrown the belt off the main drive the last two times I started it. This mower has been flawless since I bought it.

Any help !!!!!!!

Toro 283L. I believe the liquid cooled model only came with the Kawasaki.

If you need any additional info could you be more specific and I'll gladly post it !! I'd like some help before I take it to the dealer.

The model number and serial number are on a tag on the machine. The Toro model number is usually a 5 digit number and the serial number is 8 or 9 digits long as I recall. 283L doesn't get you into any parts breakdowns on Toro's website without spending unnecessary time.

Kaw recommends valve clearance adjustment every 300 hours. Has that been done in the 700 hours? If not, that's a good place to start.

Sounds a bit fuel related. You might want to go through the carb and clean all ports if the carb hasn't been touched.

If a cleaned up carb doesn't clear things up, you may want to put a spark checker on both plugs and check for consistent fire at both plugs as you run the unit. If it's an ignition problem, it seems a bit backward, as normally the coil(s) tend to fail after getting hot, not at start up--but stranger things have happened.

Fuel filter and...
Quite possibly the fuel lines, if they have been on there a while they like to corrode on the inside and you can't see it but little rubber pieces start to break off inside those lines and start to floating down stream causing a clog somewheres.

That would be my next project, replace fuel filter and lines.
