    For those who read engine tests, I have a problem right now in that I can't access the .net site to do any updates (the problem is with the server the site is stored on). However the alternative...

    Generally these pressure taps (if original) have the same thread as the rest of the backplate screws so find a screw from another OS. Other than that, as said above, the short bit of fuel line...

    I'm not an expert but the Max-III (both 29 and 35) came out in 1959 and are fairly common. These were the last of the steel finned engines and were quite high performance in their day.

    Crankshaft offset from the cylinder centre line is called DeSaxe and is fairly rare although all Mercos used it and the Fox 35 (at least) and SC 120 had it. It's not one of those things that engine...

    Derek,
    Apparently this is because when the engine has been fully run in the ring seal against both the bore and the ring land in the piston groove takes a particular "set" because of combustion...

    I tried ethanol once in an ST 46 but only on a test stand. It was a little harder to start but peak revs were only a hundred or so less than when using methanol. I also bumped the oil content up to...

    The Enya 6002 (both the 40 and 45) are baffled piston engines so the transfer and exhaust ports have multiple bridges to hold the ring in place as do all other non Schneurle engines. My OS 40SR...

    A tiny drop of MEKP in an eye and you'll be blind in a matter of seconds. Not sure if MEK works as a substitute for amyl nitrate but iso propyl nitrate (IPN) certainly can be used.

    Just to show you never can tell with ST carbs, this is the carb from my NIB ST S45 ringed. Same idle needle as mentioned but a similar style barrel type main needle.

    Now that we've seen photos of your engine it doesn't use the more familiar (later) ST wire needle but the old style brass body type that just about all engines from that era used. If the engine with...

    Holy cow, that's ancient and probably a bit of a collector item too :). As Mr Cox said, you'll have to turn the front housing to have the carb upright and that should fix your starting problem. Going...

    Ah yes, my bad, I'd forgotten the RC carbs had the thread in them for the retaining screws. I don't know what the venturi size is for the 50CX but the carb listed for the 60-IIIB has the same 13mm...

    Although possible to fit an RC carb it'd be messy. Big Enyas like the 60X use two screws either side of the carb to clamp it in place but with the 61CXL being designed as a CL engine it uses the...

    Agree on Frank Bowman for rings but check to see how many rings it needs. The 60-III has two rings while the 60-IIIB has a single ring. Both are model 7033.
