I have had these scooters in dry storage and only run them in the summer months.
Both bikes have the same issues.
Never start and run when cold unless I remove the intake hose and block it with my hand to simulate choke and it will start.
Iíve drained fuel removed hoses and inspected all intakes for leaks,swapped carbs,sprayed wd40 looking for vacuum issues.
Plug is new.
I have the auto enriched choke with a plastic screw type base that is causing concerns. Springs o ring plunger all look like new.
It heats up and the plunger moves,but the bike still is hard to start will not idle and needs to be warmed up to even get out of the lot. Pumping throttle bogs the engine down.
Low mileage no carbon, carb looks spotless inside and no signs of shellac or contaminated fuel.
I by passed the fuel tank and same issue.
All jets cleaned with carb cleaner wire and air.
Could the auto choke cause this issue if it wasnít adjusted Correctly
My lawnboy runs great and it sits outside all year
