Toro CCR 2000 Now runs but can not adjust carb

Jack in Michigan · Dec 15, 2014

Thanks to everyone's suggestions I finally got the Toro running, but now I can't get the carb adjusted. I can turn the adjustment screw all the in and out but no change with the way it runs. Any suggestions Thanks, Jack

If the adjuster screws make no impact on the way the engine runs, then those screws are in passages that are blocked. With fuels the way they are today, this is not unusual.

If this was my tractor, I would remove the carb, dismantle it totally, soak it for several days in a TRUE pail of carb cleaner. Then I would wash the cleaner off with mineral spirits, use tiny copper wires to "rod out" those passages just like the Roto Rooter guy does to your plumbing. Back into the carb cleaner again for another day, wash again in solvent and use compressed air to blow the passages clear.

Re-assemble the carb. Set the float level. install the carb. Get a can of Sea Foam and put 1/2 of it into the fuel tank. Then start the engine and see how much difference all of that has made. As the SeaFoam works its way through the carb, it will continue to remove any remaining residue.

Good luck.

You can try magic in a can, I have had good luck with Seafoam. Add, and run it till it runs out of gas.

Can you give us the model/spec. number of the engine you have so we can look at the carburetor and see which one you have? That might be helpful.
If you can't find that info, I am thinking your CCR 2000 is the model series and there should be another model number on the tag on the unit. It probably has 5 digits.
That number might be helpful because Toro used to put the engine parts on the machine parts breakdowns.

If by chance you are running a Tecumseh engine, Did it by chance have a plastic main jet? If it does, did you replace the o-rings at both ends if that jet?

Seafoam is an excellent product but it will not cure blocked passages every single time. I am not saying that he should not try it. I am just saying that Seafoam is a chemical that has certain limitations.

A Toro CCR2000 should have a Suzuki engine and it is not adjustable. The little screw in the flange in the front of the carb is an air screw and will have very little affect on the running of the engine. If it is not running correctly, probably still has the high speed circuit a little plugged, find some SEF Fix it Fuel and use according to the can, I have had really good luck using that for a crappy running engine.
