Did you change the fuel cap .
consider changing it , if the cap is old or not sealing well air comes in and causing this problem.

paul 46 here.
all being well and compression and spark and timming , muffler is clear , carby is clean , and diaphrams are all ok , fresh mix , and fuel filter and lines are good
does the unit run with 2 stroke mix in the plug hole - ?
if yes assume compression and spark are ok,, if no check compression and spark and muffler
will the unit run with 2 stroke mix sprayed into the carby throat ?
if it does sounds like you have a air leak somewhere in the intake system
could be at barrel base gasket, c/case joint, manifold boot/ block gasket, carby gasket , impulse hose ,if this unit has one , c/case main seals leaking
2 strokes need air tight c/cases in order to pump fuel / air / oil mixture from c/case to cylinder
and to create a vacuum for entry of fuel/ air / oil mix from carb to c/case
symptoms of air leak are -: hard to start, wont idle, stalling, low power, inconsistant idle, over rev
pressure and vacuum testing can be done by blocking off intake and exhaust with rubber and metal plates , then fitting adapter to spark plug hole , and placing piston at bdc , pressureise cylinder to 7 to 8 psi of pressure and check areas , base gasket, manifold joint, main seals, , impulse hose ? for leaks with soapy water - if leaking bubbles will be evident
if no leaks and pressure is held at 7 psi for at least 2 minutes with dropping - presure test is good
next do the same test using vaccuum again go to 20 - 30 inch / vaccuum
if vaccuum held unit is ok
suggest take a good look at carby particularly if P and V test are good and spark coil tests good with a coil load test using a spark gap of 6.00 mm to stress the coil ( simulates spark under compression load)
have a look and let me know what you find
