Oil/gas mixing ratio

[BruceG]

Would a IT7/ITS racer answer the above. My recently sold 88 ITS RX7 has the premix injector and reservoir removed(as so many have done). The new owner would like to know the ratio of oil to be mixed with the gas.

THANKS, folks!!

I've been told on mine (12a though, not sure if it's different than a 13b) it's 1 ounce per gallon, I ran that last time I tracked it and it was fine all weekend.

I've been using 1 oz per gallon for 10 years with good results.
