Just found the forum after doing somes searches for info on the Qualcast b66 cultivator.I have just aquired one due to having my merry tiller cadet stolen.The b66 seems to be the same with a different engine.The machine runs and does what it says on the tin with a bit of help. The revs need sorting out as they don't seem to work on the throttle and there seems to be a lot of linkages which i'm not too keen on messing about with,without some detailed information or a tuning manual.Does anyone have one i could get a copy from.Any help would be most appreciated.Steve
