Is this such a thing? If not, why not? How hard would it be to design a fuel pump (either vacuum or electric) to pump a ratio of oil and fuel? We mix fuel and oil by volume, right? Wouldn't a fuel pump that had a two draws, one for fuel (normal sized) and one for oil (50 times smaller) draw a ratio of 50:1 therefore negating the need for a more complicated carb injection system? Obviously the carb injection system is the way to go if your engine has that option, but since mine doesn't, I'm trying to come up with a solution. One of the unknowns is; will the ratio stay the same at different power settings (more likely a problem for the vacuum driven pump since the electric would probably just put out a constant 3 psi or whatever) Anyway, just a thought that hit me last night. Please discuss.
