Picked up a non running Rally awhile back. Didn't realize it was a white elephant. Only made for about 4 years. The card was so degraded that the jet towers were crumbling. Turns out that card was only produced for that single engine, which was only produced for those few years. What a nightmare. I have tried several generic carbs and it has been a tuning nightmare. It runs and is a strong little machine that is perfectly sized for teenagers, but man I am turning grey trying to get it running right. Anyone have any experience with this model?
