Chainsaw Repair

I didn't put my saw together and have no clue but always assumed it didn't.

If your talking about the 52mm big bore with 064 piston. Snoopy put that saw together. I think he used Threebond 1194, but you would need to look. I know it's sealer, just not sure what he used.  (or maybe my mind dont remember and is wrong) 
I measured it but dont remember. The squish on that one could still be tightened a little (take off the base). But seen no reason to on a work saw.
