the LPG used to work fine, I think it's gone out of tune, it will run on it but last time I used it it cut out on me and I could smell gas, so was going to take it to a specialist LPG place, but haven't got round to it yet. I'm not keen on messing about with it!
tbh I never used it a lot - before I put the leccy fan on it took a fair while to warm up, so wasn't worth switching it over on my 6 mile run to work
