HI, I have a KYMCO PEOPLE about 6 - 7 years old. I treat the fuel with good proper treatment. I took it to the shop to get it going every season. Now I am home in MD and want to start it. I bet it is only a matter of getting fuel to the plug. any tips as the good man in FL who got it going annually never charged more than $30. I didn't get the feeling it was ever anything like a junked up carb considering nothing I own gets that problem as I am good treating the fuel properly.

Question edited for clarity, typos and spelling.

Engines only need 3 things to run

Fuel, which must be clean and not 2 years old.
Compression.
A Spark at the right time.

One of the above is not there on your ATV. Flywheels don't break. Check the spark plug is clean and correctly gapped.

If you didnt treat fuel before storage last season then likely the carburetor is fouled. Try adding a fuel treatment e.g. Seafoam, but likely ithe carb will need a thorough cleaning or replacement.

hi Jeremy.
this is what i have found.
Antibiotic susceptibility and treatment guidelines for K oxytoca infection are virtually identical to those for K pneumoniae. In one study of very ill patients, K oxytoca bacteremia had a 21% mortality rate at 14 days. Rhinoscleroma is treated with combination antimicrobial therapy for 6-8 weeks.5 Sep 2017

WOW !

Although these answers are correct many are not probably. Valves are not going to go out of adjustment during the off season etc. You need to simplify it. You need gas, fire (spark) and air for a motor to run. Usually it will be the fact that the carb was not ran dry at the end of the season and fuel stabilizer was not used so the carb is dirty. You can pull you plug and see if it is wet with gas or try some engine starting fluid sprayed in the carb. Dry plug means no gas, no run with starting fluid mean no spark. Make sure fuel is on and the obvious has already been done. 90% chance dirty carb.

If replacing the carb fixes the issue it is likely just dirty or bad fuel in the old one. make it a habit of running your mower out of fuel at the end of the season and ALWAYS use a fuel stabilizer in your outdoor power equipment fuel

drain old fuel first and replace with fresh,then check fuel filter,carbs need to be cleaned after sitting so long, yes there should be a constant flow of fuel
