Hopefully you guys can steer me in the right direction as i have run out of ideas. i have a 1990 hyster sideshift +1070 forks model 2.5xl serial no. B187V02299L (S/O 130785) with a Mazda VA LPG engine. Its always been a pig to start as it may get used once or twice a week but it finally wouldnt start and i ended up wrecking the starter motor. fitted a replacement and it wouldnt go. took the rocker cover off and discovered a load of sludge and realised the head gasket had gone, done a compression test to confirm. got the head off, had it skimmed and fitted a new head gasket, still no start. got a impco model j kit and replaced all the gubbings inside. replaced the coupling to the gas tank, new coil ,spark plugs, distributer overhauled with new bearings, rotor arm and cap. did run for a couple of seconds and stopped. got a reair kit for the ca50 carb and still wont run. the only success i have had is when i disconnected the gas and empted the hose of all gas, reconnected the gas and it started first time and ran well [wouldnt idle] for ten minutes, switched off and tried to restart about half an hour later, cranked over but wouldnt start. any pointers would be appreciated
