Only runs on choke - Delta Model DT2400CS Pressure Washer 5.5HP

need vehicle make and year. "Full" choke will always flood the engine causing it to dye. once running reduce choke. Is this automatic or manual choke?

If you have a choke you have a carb(s). If it will only run on choke the low speed circuit is likely dirty/plugged. If it will run at medium or higher throttle on choke only you may have further carb pluggin gproblems and/or a plugged fuel filter or pinched line etc.

dirt or water in carburetor.Choke helps suck more gas in engine to run better.

Use the diagnostic sheet attached to help determine the problem.

This means you have an air leak somewhere adding more air than fuel with the choke off. With the choke on it blocks off the fresh air coming in and mixes with the maverick air from the air leak. You need to find the leak and fix it or you may damage the unit

If your bike will only run with the choke half way out it's starving for feul. You have a clogged jet. By choking the bike you cut off the air and allow more feul to run through the carb.

let it warm up with choke closed manually after it starts to stall with choke closed open it and dont let it stall u can learn to play with the choke a little to get it to run right GOOD LUCK!

They aren't designed to run with full choke on, the choke is for starting cold engines only, many times you can choke them pull the cord a few times and then turn the choke off or turn it down to start it. Then slowly reduce the choke until it runs fine on its own.

Sounds like your flooding it out with the choke out. Try the next time you go to start the bike when it's cold with the choke out and when it starts push the choke all the way in and keep it running with the throtle. If it runs better after doing this then your flooding it on start up. Use 1/2 choke to start cold and see what it does. Good Luck

2000 rpm and I cleaned bottom of carbs. Someone told running them on full choke would foul out plugs.The bike runs but only when I pull choke all the way out.If it only runs with the choke on it might have a vacuum leak or an air restriction which the choke is counteracting. (very lean fuel mix). To locate a leak you could try spraying CRC around the rubber carb connections and see if the idle speed is affected.,
