> Hope this email is appropriate to send. I’m hoping that someone out in Triumph world can provide some clarification on carburetors. Currently, Zenith Stromberg carbs on my 1975 TR6. The car has been running poorly since Trimphest (too many RPMs?). And then it died completely but turned out to need a new rotor. Asked the mechanic, Mike, to take a look at the everything to figure out what can be made better. What he found was the carbs were dumping gas into the cylinders especially when starting, to the point the gas was washing down the cylinder walls preventing the rings from sealing. Result was a lot of white smoke.<br>
