RE: Silver Swallow Pulldown
I can only take 0.6 grams out of the piston because you cant get the piston pin out, its a pain that way
The rest of the motor looks like it will run,,,,,, the contra is quite tight but , I will free that up
Slowly building it up
I will use an 8x6 as that heavy piston wont like to rev
Piston and rod and pin are 6.8 Grams
