I am running 30% Sidewinder in mine and it runs great.

Hello,
Werks 30% is the best fuel I have ever run with my RB engines. It clears out well and runs cooler. A good combo would be the Odonnell ODO99 plug, with Werks 30%. If its modified run the ODO97 or hot plug.
Put the RB S5 or S7 crank in your S3, port it, and run a turbo head. I call that the RB Speed... LOL!

I didn't add the shim

I run 25% Byrons in all my RB's & have for a while. The motors are clean on the inside when I inspect them & they run cool & hold up for a long time.

Sorry if this is off topic, but how is your Mach 427 engine running Mike? Did it last long? It looks like a good engine for truggy, and it's super cheap.
Thanks!
Thanks!

you need to add the shim or it will add to premature plug failure

chrobar, the 427 is a great motor. has a smooth power band and pretty good on fuel and great on the pocket book. it has about 4 gallons and good compression and good pinch.
jamminary, i took out 1 .1mm shim and added a .17mm shim in its place. thanks for the info.
