the new gasket between carb and air cleaner box should fix your primer problems or is it the same since you replaced it ? with the air filter out and back fitted up try priming and look in there , you should be able to see if its working when all fueled up .
did you clean out the main jet ? it is the nut that holds on fuel bowl , if you look at it you see one lareger hole through it just above the nut part and in the top a tiny hole ? make sure they are clean and free the tiny one catches a lot of people . poke a jet cleaner or strip the plastic from a bread tie and gently poke it in untill your sure all clear . did you reset the air gap when you had flywheel off ?
take a job card or business card , put between the ciol and flywheel , turn until the magnets suck it too flywheel and lock it up there all set .
is it a blade bar cutter or bar with blades ? could be out of balance as they do when older and been sharpened a few times . check it and see if it balances on a screwdriver .
see how ya go there bushy , even old worn and smokey they still will start n run unless its valve clearance too but we go into that later .
