I have no doubt that this subject has come up before, but I have done a search with the search facility, and trawled through pages and pages, and cannot find anything.
I have 3 square barrels, heads, pistons, sleeve bolt assemblies,which I have accumulated over time, and would like to identify them, as they could soon be in danger of actually being fitted to something!
#1 has no markings, has a round inlet port 1 3/16" diameter, and came with a 2" long cast ali downdraught inlet manifold, flanged for an Amal carb. It is on unused standard bore, having been apparently re-sleeved, and the transfer ports have been machined out to the bottom of the liner.
#2 is marked MD, so that does seem self-explanatory! + 0.40" on a new rebore and piston, it has oval inlet port, with a matching steel downdraft inlet manifold for an 1 1/4" Amal. The transfer ports are actually ported through the liner, unlike #1.
#3 is marked M20. it is + 0.030", again on a fresh rebore with new piston.The inlet port is oval, measuring approx,1 5/8" in width.
I do have a couple of manifolds suitable for Villiers carbs as well.
Any clues much appreciated.
