Hi Jaffa, , I guess you are not getting Powertorques in the condition mine always come, most of mine are pretty trashed and I usually have to strip them down, find a base that is not rusted out, strip it and paint it and then re-assemble with a motor that has reasonable compression and then get it up and running and the mower in a good presentable condition, with 4 good and matching wheels etc. This usually takes me about 2 days to achieve. As for the carbies I have a set way of setting them up and I can almost guarantee that once I set one up it will work fine. The things that kill me trying to get right is the stupid kill switch setup that will sometimes ride up on the cam and get stuck if somebody pulls too hard in switching it off and the other thing that really does my head is the rubbish float needles, that sometimes work and sometimes don't and nobody seems to have a fix for that. PM me you phone number and tell me when it suits and I can give you a ring
