My '68 tr-10r will start and idle fine. It will also go into gear (forward and reverse) fine. When I throttle up it will cough and sputter. I've checked the compression, all 3 cylinders are over 115 and less than 5 apart between them. I have fresh gas, a vented gas tank, a hard primer bulb, and the fuel filter is clean. In adition, I've recently replaced most of the ignition parts and the wiring harness. I'm convinced it is a carburator problem. I am not that good with carburators. I checked my manuals (I have two)and they both give detailed instructions on carburator rebuilds. Is there a way to "clean" the carburators without doing a complete rebuild? Any help would be greatly appreciated.
