So I checked my omp today and it looks like the lines are dry. I premix occasionally, probably about every other tank. Is my engine screwed from running without omp and premix by the previous owner?

 

HMMMMMM, lets check the crystal ball on this one. LOL


Does the Engine still run? Yep, well then it is OK at this point. May have some accelerated wear but if it runs then stop worrying about it.

 

Have you checked the MOP for flow? Easiest way is to let the engine idle and see if the lines fill up. If the MOP isn't pumping, check the archives for rebuilding it.

 

Also check to be sure the OMP lines aren't clogged up, especially at the connections.

I'm having the same problem, can't get the OMP to pump. That's after swapping in three different OMPs that all should have worked fine (I'm premixing in the mean time).

Anyway I'm at the OGTA meet last Tuesday and someone says "Did you check to see if your lines are clogged?"

Duh, I'll be looking into that possibility this weekend.
