Hate to bring this up, but it sounds like you are low on compression.. 100 is an absolute bare minimum for a 2-cycle engine. Many 2-cycle engines will not run at all, below 100psi.
Are you sure that all is well with that Airsal top end? Typical compression on a good-running ped should be in the 150+ range. New top-ends will not reach full compression until they are fully broken-in, but you should be starting with something better than 100psi.
Worth looking into.
