84 SE Carb swap
 

Ok, so i have been reading up on here about the OMP. Didn't know this even existed. I'm sure im going to get flagged for asking a Q that has been asked before, but i tryed searching and couldnt find any answers. Where is this little guy, and how does it work? Whats it for? I have a Holly 2 barrel that I though might work on my car but would I have to pre-mix my gas every tank? If so that route is out, got tired of pre-mixing with two strokes, last thing I want is to have to do that with my car. enlighten me

The metering oil pump injects a small amount of crankcase oil into the intake manifold to lubricate the apex seals.

With your new carb, you can either modify it to accept the metering oil lines, or eliminate the system and premix 150:1 with 2 stroke oil.
