lack of power - Technical Troubleshooting discussion in Forkliftaction's forums

Cat Lift Trucks (& Caterpillar) GP18K:
lack of power

I have inherited a service problem, my customer has a Cat GP18K forklift with very low power, its an LPG engine, it stars instantly, tick over is smooth and quiet, but when the accelerator is pressed very little happens. when you engage drive in either direction it barely moves. I have never dealt with lpg systems before so any help would be appreciated. it has an Impco model 100 gas control unit (not sure what its called)

cheers in anticipation zzzzzzzz

so after replacing spark plugs and leads, fuel lock and regulators I found the fault. it was the choke which was jammed shut due to a broken piece which was holding it closed. after removing and repairing the choke everything is good, except the bank balance.
