I am getting fuel in the engine. So far I have replaced the electric fuel pump, put a fuel regulator on and it's set at 4 lbs. Of pressure, but i'm still getting gas in engine. The last thing I did was put 2 new twin solex 44's on and this didn't help at all. I was told the engine is a 2007 cc, it had twin weber 44's on it. I also did a compresion check 3 cylinders held good at 140 and 1 was at 130 but was slowly droped to 100. I'm running out of ideas.

There are three ways fuel can get in the oil. First, you dumped fuel into the oil filler cap--not likely- right? Second, fuel can leak into the intake runner when the intake valve is closed. Fuel then can leak past the valve seal and into the oil. If this happens, the engine will barley run if at all--also not likely. Third, the piston rings are worn out. When fuel is taken into the combustion chamber on the intake stroke, the piston is on the way down. The fuel/air mixture is then compressed as the piston goes up. It is here, before the spark plug fires, that is the most likely cause of your problem. A worn compression ring will give you a bad compression reading and cause fuel to leak into the oil.I suggest honeing all the cylinders over-sized if needed and put in new pistons and rings.
