OMP disabling and oil premix set it straight
hey all
i have been reading through the 2nd gen archives and seeing the LONG write up on premixing im still confused so can someone lay them straight for me? like:
1.in an 86 rotary the tank is a 16 gal so how much 2 stroke oil is need?
2. what kind of 2 stroke oil is best?
3. what type of OMP does the 86 have?
4. how do i disable it?

1) if you want something around a 100:1 ratio, and you're putting 16 gal in the tank, use 20 oz. of premix (1.25 oz per gal- 1.28 oz per gal would be exactly 100:1)
2) General consensus is any two-stroke oil with the TCW3 rating (for good dispersion in the fuel, and ash content)
3) Mechanical- the entire external OMP system is easily removable with the TB/ upper intake manifold off. You will need 4 bolts to plug the oil metering nozzle locations (available at Mazdatrix), and a block-off plate for the metering pump location
4) see #3

2. anything that's labeled TCW-3 (Valvoline Multi Purpose 2 Stroke)
3. mechanical (another good thing about S4...you can just yank it off)
4. either put a block plate on it or remove intake manifold and install 4 bolts to replace the oil injectors
(don't ask what size threads..been too long ago)

You still haven't got that thing running right, Digi7ech?, LOL...Two dimes work well- they're to keep the drive gear from "slopping" around in there...When I did the rebuild, I just left the block-off plate & dimes alone, but removed the drive shaft from inside the front cover- I'm hoping the dimes are still in place, ha ha...

I've got a question: If I premix as a supplement to my OMP, do I still use the same ratios, and does it still help with the carbon deposits? I hate having an s5.......I miss my s4's.....

just get rid of the omp. its gay anyway. just my opinion. just block it off and put some 2 stroke twc3 in the tank. i beleive half a qaurt per fill up. or one oz per gallon

half of the premix i buy is over $8/qt
with filling the tank costing around 50cdn thats almost $55/week
I've left my omp on and once every few fills i'll add some premix just to help.
