piston?

[sdblaster]

I just got a 67.50 piston for my blaster got every thing back together the arrow pointing towards the front.kick it a few time it did not seen to have that strong a kick.well it started but did not sound that great....it sounded like the rings were rattling in the cylinder and would not stay running? wrong size piston? it seemed tight.........lost..

take it apart and bring the piston and cylinder to a machine shop and tell em u want them to run a micrometer through it and tell them the size.5 10 bucks at the most to make sure,but if they match put it back to gether and break it in,might run and sound better after break in.hope this helps
