For those of you running the 20b with the oil meter system disconnected, what ratio do you use when mixing your gas?

 

I think it's 100:1 (gas:oil), just like 12A and 13B. Use 2 stroke oil because regular 20W50 etc seperates in the tank. That's why Mazda used an OMP which injects it directly into the engine (or carb on pre '85).

 

In talking with Cam, I use 90 to 1 for anything under 10# and 100 for racing. I was just curious as to what others are using.

For the oil, I use syn 2 stroke racing...either bardall or....can't remember as it is in the car.

I am racing this weekend coming up...looking to crack the 200mph barrier...again!

 

How come you use less oil when you're racing?!

just wondering!

 

we were toying with the idea of making a stepper motor controller to use the stock pump. it might not be worth doing though

sorry...other way around. shoudn't be typing and working at the same time! 100:1 regular and 90:1 when racing.

I have had a real problem fouling plugs and thought that part of the problem was running too much oil in the gas. Oil well, so much for the easy fix so I guess I have to switch to the race plugs....

 

Are you running 9's right now? What type of ignition setup are you using?

 

I am runing the links system. Can't get the fking thing figured out...just keeps breaking down at anything over 7/8 pounds. There are new b10egv plugs in it (per Cam's recommendation). The change didn't make any difference. Any help is appreciated as I am flying into the states tomorrow and am supposed to race it.
