So I have a 2018 Massimo 500 and bought with 100 miles on it and only 400 now. It has worked and ran perfect. I noticed towards cooler weather it wasn’t idling and then just not running good at all.
things done - replaced the ignition coil replaced the plug checked cord for voltage. Drained gas cleaned tank went to a Rec fuel. Cleaned fuel filter screen at bottom of fuel filter. Cleaned main line and screen (had some residue) no air leaks I can find. Checked cleaned air filter. Cleaned and tested air intake control. Removed cleaned and tested the device moves o ring also fine.
I am not at a loss I can not get it back to where it was I have attached video of running etc
