Thumbs up oil metering pump issues

Hey guys the people who apparently rebuilt my engine forgot to install the omp to throttle thing. The long peice on the OMP is there but the peice from my mikuni carb to that peice is not there. I hooked the long peice to the water pump outlet so that the OMP is like constantly running at more than normal ya know. At idle it's puffing out blue. But man am I lucky I haven't blown this engine up, had it for 5 months now. Plus I just tuned the carb and man did they not know what they were doing lol. That thing was messed up bad. It needs to be timed and had the driveshaft pulley (aluminum rx7.com one) put on it. SO ANYWAYS. I was just wondering what I could make or do to hook my OMP back up to the throttle on the OMP.

Pre-mix, or get the rotary aviation 2-stroke pump.

Also, make sure you wedge a 2x4 between the seat and the clutch pedal before you take the old e-shaft pulley off.

That won't help the fact that there's still no throttle linkage...

My mikuni didn't have the omp rod, so I made one from a 2nd gen one. The 1st gen rods won't work. You will need to bend and cut the 2nd gen rod to fit, then drill the tiny hole at the bottom of the rod for the split pin. The 2nd gen rod is a larger diameter than the 1st gen, so you will need to drill the hole in the omp lever larger.

I have the long rod hooked to the OMP there I have it hooked onto the water housing, but it doesn't hook to the throttle. I need to know what to do to hook it up.

It doesn't 'hook to the water housing'. It hooks into the lever shown in the pic on the forward side of the carb.

That "piece" is gone not there BOOM gone. After I got it back from the shop I just now found out it was gone. And it's been 4 months so I really can't do anything with them. Where can I get this piece at? Thanks guys.
