According to my FSM, when the engine is warmed up, you should be getting 1.8 - 2.2 cc/6 minutes at 2,000 RPM. Not quite sure what that equals in drips per minute.

I have an OMP plumbed into the air horn of an Edelbrock carb. The OMP is jacked open to the 9 or 10 o-clock position (there is no way to rig a rod and/or I'm not going to bother lol). At idle it drips alternating every 5 seconds I think. Higher RPM speeds up the OMP shaft so I'd imagine it will drip slightly more often.

I've been beating the ***** off my 7 latey. Parked her up in the driveway last and oil was EvERYWHERE...! Poked around a bit and come to find out one of my lines from the OMP popped off.... hey, at least I know she's working. I have a 2nd gen 4 line pump Y'ed into two lines then to my Nikki. I secured the Y better and all is well again.

Haynes 79-85 manual = 2000K rpms @ 6minutes = 2.0 - 2.5cc

88 Mazda Workshop manual / Turbo = 2000K rpms @ 6minutes = 5.2 - 6.6cc

88 Mazda Workshop manual / Non-turbo = 2000K rpms @6minutes = 4.2 - 5.6cc

Mine is working what sucks is that the car was running perfect up until I added the 2 stroke into the gas just to be safe. NoW at a constant speed the car would jerk a little. I guess I should have left it alone but at least I know the omp works. Now to run all the gas out, after that I should be good. No more pre mixing for me.

As I recall from another one of Touring's posts he dumped in the whole 16 oz bottle.

On top of a correctly functioning OMP that could be enough oil in the gas to produce some staining over the tail pipe and a few hick ups once in awhile. Should straighten out when he uses up that gas and the engine will be well oiled.
