Hi Ted, just to clarify, the motor that Bumps is playing with is not a powertorque, it is an earlier motor, I think a full crank that he welded a flange onto the inlet spigot and then bolted on the plastic adaptor to take the LM carb.He regrets this but now the challenge is on to work out why these carbs won't work properly, it no longer is a case of just wanting to get a motor running, we intend to solve this problem before we die, whatever it takes. This motor he rebored, new bearings/seals and it runs well, but it performs in exactly the same way regardless of the carby we put on it. Mine all do the same. Disconnect the kill switch wire and in the stop position, full revs, run position, full revs and the motors will die anywhere in between
