What would be the best decarbonizing additive for my yammy 9.9 2 stroke and 100 four stroke? I have heard of OMC engine tuner, is there an equivalent for yamahas? Thanks
There are a number of decarb additives, but a decarb spray is more reliable for 2 strokes.<br /><br />Do not decarb a 4 stroke. They do not burn oil and do not require regular decarb.<br /><br />Good luck.
