I cleaned the uni air filter checked the plug they have good spark replaced then just for! had carbon building only 400 miles on the machine it use to idle at 1000 rpms now around 800 if i give it gas it seams to do ok,  it will start and run if one plug is left in the right side if i do this on the left side no luck, smells of strong gas in the exhaust dumped some stable in the gas ran for awhile letting sit over night and will try again checked the diamostic all good tend to lead twards a injector on the left yes i ran the gas out and put fresh in same as my wifes so the gas is good and does anyone know what the idle should be
