:DPROBLEM SOLVED after checking for ac from stator this proved ok so i swapped a cdi unit over from a working scoot i had and bingo we now have a spark i then brought a new performance cdi off ebay and got the engine running but even at full throttle it would only run at 1000 rpm cleaned out carb no improvement swap carb from running bike still no improvement so off came the valve cover to check valve clearences both were spot on on next step check cam timing but when flywheel was set at tdc cam sprocket was out of line reset cam timing and turn engine over by hand and valves were hitting piston WTF so reset cam timing back to normal and turned engine over with screwdriver in plug hole to find tdc and lo and behold timing mark on rotor was 90 degrees after tdc mark on casing so off came the cooling fan and bugger me the crank nut was finger tight off came the rotor and the woodruff key had sheered off 1 30p woodruff key later everything was set up and reassembled fuel turned on ign turned on and 2 kicks later VAROOM YEE HAR ENGINE NOW RUNS LIKE CLOCKWORK only thing is is slow to pull away from stand still but then again its only a 50cc 4 stroke ped might try fitting 2.7 g rollers in the variator as its got 4g rollers fitted as standard so lighter roller should keep it in lower gear longer so it can pull away quicker

hi jr it can't be valve timing as the malaguti is a 2 stroke hence no valves lol im' begining to suspect than the piston rings have gone allowing compression to leak past the piston and pressurising the crankcase causing the blowback out the carb

thanks for the info the problem was the front variator was not opening up causing the belt to sit too high so i striped it down and found as the scooter had been siting about there was some rust on the slider once polished up with some wet and dry paper the variator was cleaned out and everything put back together
time for a road test and boy what an inprovement the scoot took off like a cat with its arse on fire i'm well chuffed thanks lads

hi folks i think ivecracked the problem i tried adjusting the idle and mixture screws and the smoking has got better however it still was not right so i tried different setings on the carb needle and set it 1 notch down from the top and now there is hardly an smoke at all thanks guys

hi jr great news ITS ALIVE ;D ;D ;D i picked up the regulator which cost me £12 and some other bits and pieces today plugged in the r/r to the socket i showed you and bingo we have got a spark so buoyed up by this success i put fresh fuel and oil into the tanks refitted the spark plug and 3rd prod of the kickstart and amid a hugh cloud of smoke she burst back into life i was well chuffed but my joy was cut short when i discovered that the head gasket had gone and water was pissing out of the exhaust i'm not too worried tho as its a simple job to do and the spare parts costs peanuts
the other goodies i got today were a full set of body work with only minor scuffs for £20 trouble is they are dark blue in colour and i want to keep the kaytana red but thats nothing a couple of hours preperation and some spray paint can't cure i will start a project thread in the other section so you can keep progress of how shes getting on thanks for all the help you and other members on this forum have given me without you help i would have given up on her ken

thanks mate now you can see why i want to get it back on the road
