Apparently it needs to have "limp home" capabilities on petrol to qualify for a Gas Certificate though it only needs to run on one to get a Safety Certificate - go figure.

I'll find out tomorrow how it's really running but the mechanic tells me it's fine on either. But then he didn't know how to reassemble the carbies, did he?

What I said is true though, a engine will not start on petrol if it is too advanced, but it will run on LPG. Back the timing off and see if it works.
