Hi Ray

From a post you made in 2007 on the Barton thread linked above.

"# Perhaps most interesting was the revelation that they (Recochem) add one half percent of Butyl Alcohol to the kero that goes into their one and four litre packages and have done so for the past ten months. This is a requirement by the Australian Taxation Office (ATO) so they don't have to pay excise on the kero. It is meant to make it difficult to run in an internal combustion engine according to page two of the following ATO document:

Sounds like the culprit! "



Adulterated kero may or may not run just fine in our little compression iginition engines. However last week-end I used the last of my 'white spirit' and IPN brew in my lovely GB 5. Ran smooth and steady.

The ATO link copied above is no longer operative.

Changed to my new batch of KCB kero and 2-EHN (Amsoil) fuel and it was unhappy, with a persistent misfire no mater what needle/comp setting I tried. Of course the DII component could need adjusting. Makes me want to go back to the white spirit brew but I have 7 litres of KCB kero on hand and a near full quart bottle of Amsoil cetane boost!

My friend has promised to let me have some AVTUR (JP-8?) so we'll try that. Price is right

A further thought. Off topic I know, and not really my thing at all, but this is close to 'state of the art' for turbine powered R/C aircraft and flown at a local club. It features a very expensive "top drawer" German made power plant.

The owner advised he does not use kerosene or Jet A-1 for the fuel base. What does he use? Automotive distillate (diesel fuel oil) straight out the bowser!
