Check that the intake manifold is not cracked or separated, extra air might cause you to need the choke. Some times the first carburetor cleaning does not do the trick. Take the carburetor off again, take out the slow jet, and shoot through it with cleaner to make sure it is clear. Now shoot through the passageway of the body and make sure that the body of the carburetor is clear . When all passageways in the body are clear then reassemble and put it back on. If the air screw is set correctly you should have a machine that idles.

Do it start on choke only and will not run when choke is off. carb need to be dip and soaked in carb cleaner , Note Completely apart no rubber or gasket in this solution. Blown out after 4 or five hours of soaking and reassembled.

How to install choke cable on 400 Kodiak atv ?


Your information is on the ATV Forum

Throttle cable: remove the 3 screws on the right side of the carb, take off the cover, there is small rubber gasket (red) Don't lose it. you'll see the cable attached inside. move the mechanism forward like you're opening the throttle to get enough slack to unhook the cable.

Choke: on the other side of the carb, the choke cable screws in with a plastic nut (10 mm i think) unscrew with your hand, if its tight use pliers or wrench..its easy to unscrew it.

What will cause newish sears 27cc string trimmer only run on full choke?


If the trimmer has been sitting for a long time it is probably the carb needs to be rebuilt. Before doing that check the plug and be sure you are getting fire. Be sure nothing is blocking the fuel filter in the tank. Be sure exhaust or muffler is not plugged, with only 5 hours on the trimmer I wouldn't think that is the problem. Sound more like something in the carb. You can look on you tube to see how to rebuild the carb if you have not done it in the pass it is fairly simple to do.
