Hi ,
Thanks for your replies.
Av8tor, I looked into that excellent thread of yours but it seems to be only on Gas to glow. As you know, I am interested in the glow to gas conversion. The St 4500 is a 2stroke glo engine and I am wondering if the use of the E85 and an F plug is all that is needed to operate this engine efficiently using 12% oil.

( My only source of E85 is 500 Km. away otherwise I would try it myself ! )

Many thanks,
Merlin.
