i have now made the required modifications to the flywheel...but, as i didnt have access to a lathe, i did it with an angle grinder (cutting disc) and a file...oh, and a large drill for a slight adjustment.
as you can see in the picture, it doesnt look like a flywheel anymore. but far as i know, it should do the job. ill test it out tomorrow
i seem to have a problem...it would seem, that i need to give the engine quite a fast pull to get a spark, the problem is, that with both plugs in, and all that compression (2 tandem cylinders remember) i cant pull it fast enough with compression.
should i need to pull it so quickly? is it something to do with the gaps? how can i make it so i dont have to pull so fast?
try spray some start yah bastard in there, thats what i do to get the cag engines going first time.
stupid as it sounds what about taking one spark plug out - start the first cylinder then put the spark plug in the second one and connect up the plug boot?

i had thought of that, but i figured that would get quite annoying if the engine stalled
one option is to drill a hole & put a decompression valve in one cylinder, you should be able to pick one up from a industrial supplies store or a large automotive retailer
the other way is to get rid of the pullstart all together & make a electronic 12 volt starter from a starter motor & battery & alloy pawl (similar to how they start karts that run a clutch)

wouldnt there be just as much of an issue doing this as trying to pullstart it normally? im thinking of the amount of torque required to turn the engine, if the electric motor puts out the same or more than me, then, wont it just twist me, instead of the engine?
then why dont you find a way of mounting the starter on the frame. maybe like the blata flywheels how when you spin the pawl one way it doesnt grip, but when you spin it the other way it grabs on because of the spring-loaded arms
