I'm assuming that you intend to run premix instead. While this is the simplest solution and provides a thorough mix, there is another option that allows you to still use the omp (thereby circumventing the limp mode problem) while drawing 2-cycle oil from a separate reservior.
This metering pump adapter is manufactured by PCV industries in Florida and sold via rotaryaviation.com for about $90 US for the one you require. Takes about an hour to install.
What this unit does is it bolts between the omp and the omp mounting surface on the front cover, acting as a block-off plate to keep engine oil in the engine. Instead it is fed 2-cycle oil (recommend TCW-3 type--- it burns cleanest) from a separate reservior supplied by and installed by you. A Nissan power steering reservior, a few hose clamps, 90 degree elbows and a length of fuel hose is all you need.
The adapter has an extension shaft through it so that it can drive the omp via the stock shaft. Just bolt it into place. (Longer bolts are supplied with the adapter as is the o-ring seal.
I've been running one of these on my 1st gen 12A for about a year and a half. Works fine.
