Spuds Porting and Tuning Thread

[spudulike]

As I hear from over the pond they are very restricted for a 60cc saw . My can was definitely cut and shut to mod it . No idea if any porting was done inside !

 

The saws are made to run pretty quiet so getting a bit of flow through the muffler will help. The muffler exhaust port side is very restricted as is the outlet side.

 

I will see what I am able to achieve with the kit I have!

Early signs are that it hasn't seized but the bearings or crank are buggered - will find out later:001_rolleyes:

It is over, the 560 has had a crank stuffer break up and the parts have dented the cylinder upper transfer and damaged the piston.

 

The saw is a write off:thumbdown:

The stuffers are thin pressed metal, the saw was split and then put together again and it looks like there is a bit of gasket in the bottom of the crankcase that may have abraded the surface of he stuffer until it wore through and caught up.

 

I am not sure if the gasket just didn't mate properly or a thin bit broke and entered the case or what but it has caused some bad damage - it is very unusual to have stuffers break up like this. A big shame as it was a chance to see how the autotune responded to porting:thumbdown:
