is this just a case of bad gas with water vapor or somthing?

can these gas tanks build up water with in them?
and if so is there any way to clean it out with freash new gas??

cheers

HAve you checked the converter for freezing? There might be a blockage in the water hoses causing the gas to freeze up and not vaporise. This could cause those symptoms. Or a bad electrical system.

Gas running issues are normally caused by electrics than gas,and yes it SEEMS to happen overnite.
Gas needs a lot better spark than petrol.As leads/sparkplugs wear it starts to run badly.
First check is at nite,get a squirty bottle adjusted to a fine mist.Have the motor running with NO light shining on it,darker the better.Watch for any arcing(blue sparks) along the leads,best not to touch.If you see arcing now,your leads need replacing.If no blue sparks are evident,give light puffs of the squirty bottle over the leads if you now see arcing yet again its the leads that are the issue(this replicates damp winter air).
In the daylight inspect your rotor inside the distributer and the sparkplugs.
If its a long time since they have been replaced bite the bullet and get new plugs/leads/rotor.Should cure the problem
BE CAREFUL NOT TO CROSSTHREAD SPARKGPLUGS WHEN RE-FITTING THEM!!!!!
Goodluck

mmmm well i have replaced my leads with some burson 100 dollor petty/gass leads, new plugs < mechanic did so no idea if he screwed them no more then 3-4weeks ago,
only 3 things i havent changed is rotor, dizzy cap and the coil
i shall replace the rotor< any special way to pluu these off? i know the early GQ patrols ones were bolted with a 7mm nut

cheers matt

ps: if these fail after replacing it i shall check the water leads as well while im at it
