Hi Guys,

I am not sure if I should change the Piston Pin and the Connecting Rod.
The connecting rod moves freely on the pin unless I apply some pressure then I feel some friction.

Also I tried to remove the piston pin, but it will not move due to time and residue built-up ...any ideas how to free it up Shall I put it acetone for a day or two?
Regards,

George

It's normal,you probably are not pulling straight on rod ,use block of soft wood and a punch and tap out . If nothing wrong and don't need to do it leave and get more time out of it .

I stole it ,flew it and gave it back ;)
