Hey there,

The O'donnell ss.21 ran like a champ all weekend at the JBRL race at ARC. The combo of the SS.21,The new O'donnell R2 pipe and header, #87 Glow Plugs and 30% nitro was outstanding. Great power, great fuel mileage, excellent tunibity as the weather was changing all day and not one single flame out all day Saturday or Sunday. I only say this as I saw many of the factory guys with flame out problems.

If you haven't tried a SS.21 you really should. It is economical, and in the long run worth more then what you will pay for it.

Combine it with the R2 pipe/header, #87 Glow plug and the best fuel on the planet...O'donnel 30% and you will have a graet running and long lasting engine in your buggy or truggy.

Have fun and I hope to see everyone at the races,

Barry
