Blaster help

[birdman906]

Hello I just rebuilt my blaster last night but now it seems doggy! Went 20 over on the piston and cylinder. Do I need to reject the carb with an oversized piston? Any help would be appreciated

No need to change jetting for the piston change.

Did you do a leakdown test after you put it back together?

No I didn't do a leak test. How and what do I do to perform this test
