Recommendation for slow 2 cycle engine plans from bar stock

[Brian Rupnow]

But please--only from people who have successfully built and ran one. I have built enough i.c. engines of the 4 cycle variety to become quite familiar with them. I may begin another engine build, but I need something a bit different, so I believe it's time for a single cylinder two cycle engine. Is there anyone on the board who has actually built one from plans and ran the engine successfully. If so, can you please direct me to where I can get the plans. I really don't want an airplane engine type high revving "screamer", rather something with a flywheel and a lower rpm range. I don't want to purchase a casting kit, but would instead prefer plans for an engine built from bar stock. Your help would be appreciated.---Thank You---Brian

I know this does not meet your spec, being made from now unobtainable castings, but the Stuart Lightweight is rather sweet, and has a flywheel:

I should think that Lightweight could be done from barstock, a few alterations to suit that construction method keeping the basic internals the same and it would make a nice size engine -

34.5mm bore, 32mm stroke = 30cc or about 2cu.in

Its not unlike the Hubbard that Classic Motors do, again that could probably be done from barstock.
