Hello all, I aquired an SL70 engine not long ago and just got it running on the bench. It idles ok, but just won't take any throttle. if I turn up the idle screw, it starts to increase rpm slightly, then starts to die. Carb is new, valves adjusted, points and timing good. I had this issue with a CT90 a while back and it turned out the issue was a bad condenser. But is seems like the SL70 condenser is not screwed on, but soldered in. Can it be tested without removing it?
