Hi Norm, correct and I could leave the mower in a shed for ten years and then it would still start up no problem with old LPG.

Not much chance of getting water in the carby or tank and no way to get a fuel blockage also no fuel evaporation .

The Honda runs smoother on LPG .

LPG vapour takes up to 30% more area in the manifold and carby than petrol which is still in a liquid state that's
why I installed a larger carby than standard so I shouldn't have lost any noticeable power.

Cheers
Max.
