okay i knida forgot that the freewheel doent work anymore, so i cant test the compression. although, after finding out what the points gap _should_ be (quite a bit smaller than italian peds) its been running better, with less 4-stroking, although it still does periodically. so i have exhausted every possible reason and have caved, and have been running with the thingy pulled out a little. so i still think its an engine problem, rather than and air obstruction. i bought this thing with the intention of selling it, but now i like it. it would be a great garage saleing ped.
