<div id="post_message_22350137">A lucky find on Ebay (and low buy it now prices!)
These engines were misidentified as Dunham's, but easily recognised as Burfords now back home in OZ.

They were both stuck but freed up fairly easily by taking off the head and backplate then using a rod in a drill press to push the contra and piston down to get them moving (avoids strain on the conrod). A little polishing to remove the head scratches and they look almost new.

Both run well, one or two flick starters hot &amp; cold.

The Elfin 2.49 replica has a rectangular bolt spacing so does not quite fit the same mount as the original Elfin. The Elfin has a cracked prop driver so was tested with the GB's - another little job on the list.
The GB 250 is a replica of Gordon's early Sabre 250, but is a kind of halfway house between the MkI and MkII versions.</div>
