I noticed this with a Mini Trail.. sits 2 years, starts in 2 or 3 kicks.
Today I got Jazz scooter running, sat since 2014 or 2015.
Battery was flat , so I pulled it out, hooked a booster up.
Didn't drain gas or add any. It started pretty quick, I mean it may have bee 30 sec with eat art not sure.
Dontveven know if it has a choke or a petcock.
Hey at least it has a kicker.
After it ran a bit, I disconnected the booster and it kept running, so I took it for a ride..
When I got back to the shop I did this.. see pic.. lol..
