I've got a Honda generator that has been sat for nearly five years since I last used it with petrol still in the tank. On the weekend we dug it out, opened the valve, waited a few seconds... and it started second pull. I had run the bowl dry when it was stored away, which probably helped... tank looked good though.
Sadly my local LPG filling station is a little bit in the wrong direction to go to all the time now, so I'm going through petrol at quite a rate :(
My garden tractor thingy is like that. Sits outside unused in the elements all winter. No cover or anything. Never gets any maintenance. Always starts first turn of the key. I put it down to the Kawasaki motor :)
Only time I had fuel go off, was my first motorbike, my dad took it off me cos I was only 15, 3 months later went to start it, nothing, fresh petrol and it went, but I'm sure fuels will have more additives now than near on 40 years ago, lol
Probably on the wrong topic but earlier this year I saw that Orangebean and Gilbertd were working on the same LPG problem/equipment that I have on my 98/99 P38 - ie Alisei N type Zavoli has same numbers on as your pic you published and after changing spark plugs and coil pack runs nicely on petrol but won't switch to gas. I think now that the poor running was the start of a gas problem. Since I am stuck in Spain a long way from people in UK who fitted the system do you think I should get a diagnostic lead interface and copy of the software for my Windows XP laptop ? Could you please point me in the right direction, pref cheap or free as not much money here!!
Where do folks stash their gas ECU on a GEMS motor? I was thinking about putting it next to the GEMS ECU, for convenience of cabling etc?
Only got a single point on my GEMS, but the emulators etc are all bolted onto the back of the GEMS box. There's certainly space there to fit a "proper" LPG ECU and, as you say, makes cabling easier
Both of mine have it on the inner wing next to the battery. Fine unless you have a huge non-standard battery fitted.

Only a few faults will stop it attempting to switch to gas - Solenoid coils will usually cause it to cut out on switching if they have failed, though not always. It could be a failing sensor (temp sensor being one), or a wire thats either broken off or been unplugged/not plugged in properly.
Diagnosics software can eliminate some of the guesswork on that score, so getting hold of a lead would be a good idea, though checking the connections would be a good first step as well. If you can get to both solenoid coils then checking their resistance on a multimeter won't do any harm, to get a meaningful reading you may find it easier to disconnect them first. At the same time inspect any of the wires running to the tank if you can just in case there is damage to the cable.
