Thanks. The most likely cause of this is simply that your mixture is adjusted to be too rich. In english, this means that the gas/air ratio is too high. If your exhaust pipe is black this will confirm this problem. When you back off, uncombusted gasoline finds its way into the exhaust and the heat there causes the unwanted flatulence. This will require a carburator adjustment. Since I am a fuel injected hacker, I have no carb experience, but it should be easy to find. -- Jack Saltiel Cambridge Digital Systems {wjh12,talcott}!cdstar!saltiel "Nailed retreads to my feet and prayed for better weather."
