Re: poor starter
Do you have any gas leaks around the gas convertor or gas lock off valves???
Gas motors should start pretty easy if the convertor is full of gas, next time you have time, turn the ignition on, and wait about 20 seconds and then try to start it, this will give the convertor a chance to fill with gas if it is empty.
Also, if it doesnt start then, get a bucket of hot water out of your tap and tip the hot water over the gas convertor.
Let me know how you go.
p/s My clevo has a 425 straight gas carby and starts good in any weather.
