Hi all. New to group. Have a used 2000 seedoo RX that fouls plugs very quickly. Dealer says typical 2 cycle machine. Have owned it for 1 year. I am an ASE certified automobile tech and have been for 35yrs. So I do not believe dealer we got it from. So what should I be looking for. Plugs are new OE NGK's and gapped @.043". Additionally is there a way to scan machine without factory tool. Thanks to all. mramsh.
