Thanks Kip,

Yeah I hear Perth is nice but have as yet to make that trip. I suspect you are right about the dried up fuel residue. I have a friend with an ultrasound cleaner for injectors and I'm hoping that will do the trick. I'm convinced that nothing is getting through them at the moment.

As for the Avgas I havnt tried that but have ample access to it as my other pastime is flying. We often "dispose" of 100/130 grade fuel when defueling it from light aircraft when they are overweight. Its illegal to put it back into another aircraft due to contamination risks in handling so it usually ends up as lawn mower fuel. Never occured to me to try it in my Benz.

Anyway I'm back on a plane to NZ in April and am determined to get her running then. I'll post an update.

Cheers,
Daryl
