well i dont think its a leak and the carb o-ring looks fine its a nova carb ring its thick but it dint look damage its not old. maybe should just remove the sealent than.
cdc on here said to remove a shim to run 20% with a hot/meduim plug what do you think of that will it do any harm ? the s5 has 2 shims on it already but it hasnt ran right with a meduim plug so i was thinking there was a leak.
the shims are .20 mm.
