Hi there fish, thanks for clarifying the dual fuel setup.
I just was wanting to make sure that petrol was not needed for easier startup.
And yes I will stick with the lpg fuel.
As a matter of interest for yourself,
Model : GP050RGEUAE83.4
Serial no : A875B16288Y.

There is a guy in Scotland here that refurbished carburrettors/lpg and is well versed on the type that is on my lift, he said some parts might be an issue, but fingers crossed it's just needing a good clean out and tuned.

Thanks again for taking the time to answer.

Cheers,

William.
