I just got a TE20 in and have been redoing some of the older " fixes" that have been done to it over the years. The original carb was replaced a while back with a Chinese knock off, luckily the previous owner still had the original. It ran on the Chinese knock off, idled nice but stumbled on a rev and then would die. I went to the original, cast iron carb and tore it apart and seen a fair amount of rust in the bottom of the bowl, but other than that it looked clean. I soaked it for a day in Chem dip, blew it out, wire brushed the bottom rust with a dremel and ran a wire through all the passages and reassembled it with a new kit. Installed it yesterday and it blew black smoke and appeared to be loading up badly, it would rev up but man it blew some black smoke.So I took it back off and disassembled it and it s soaking again. Next I m going to drain all the fuel, refill with fresh fuel ,install new points rotor and condenser, then do carb all over again and retry. What do suppose is the best chemical to clean the fuel tank with the baffles still in it and what do you use to clean the rust out of the bowl of the carb? I think there is rust in the passages.I m guessing he had water in his gas as the new carb had some brown powdery type of substance in the bottom of it as well. But wasn t rusted. The tank isn t terribly rusted but has some in it according to the sediment bowl. Any how sorry for the long post. .
