Hi all, Having probs with my DT2. It has been runnig a bit rough, generally running rough, stopping, hard to re start, lack of power...
I cheked the spark plug, it was a bit wet and oily. i have definately got the oil/petrol mix right. so i was thinking dodgy spark plug or running rich.
anyway i have changed the plug, i stripped the carb, cleaned it, checked for blockages. cleaned the filters and fuel tank, re built it, adjusted the mix screw when at idle. I had it stood in a dustbin (!) with water in and opened the throttle, heard the engine running a bit rough again as if fuel problem, the revs decreased then increased.
spark plug was not oily. the only think i can think is smoke from the exhaust getting sucked back into the air inlet? Dont really want to look at crank and piston, any chance it could be that? the float in carb worked well. I dont really know much about the carb, the float seems to adjust a valve, and the throttle moves a needle up and down. any help appreciated! cheers, gareth
