I just bought a 100hp Mariner oil injection. It sounds and pump water ok except every ten seconds or so it back fires once. I replaced the plugs and fuel filter, flushed out the carbs by undoing the screw where the float sits and pumping fuel through it, carb four had a bit of oil in it.
The motor did not run well before i replaced the above parts and did a clean.. The only thing is the back fire. Can someone please advise me on what to do to rectify this problem?
