I have the same set up but  1 1/8.
Is the piston moving freely.
Should be bronze with NO spring.
Check the oil in damper To much causes misfire at revs. 
                                   To little causes hesitation at low revs. and I use Sewing machine oil 

 Both  problems  i have experienced.
Float Bowl loose which changed mixture making it rev one minute and die next.

Also check rubber hose to carb is not collapsing ,Old hoses seem to fail with modern fuel.
