Hi Folks
The idea of fitting a Husky piston into a Stihl has intrigued me since I was told about it when first rebuilding my 066.
I never fully understood the theory of how it gave such good gains until I managed to wrap my head around it in the circle crank thread.
Having decided to fit a Husky 288 piston up to my Stihl 066, and put things into motion to get it done, it got me thinking about my little 026.
Could it be improved on?
It seems the general consensus is to machine the piston top flat and cut the squish band flat to match. Machine the base to get the squish back and they run strong with a lower exhaust port.
This however results in BIG compression numbers which is something I want to avoid in a work saw.
Idea:
Fit a 44mm Husqvarna 246 piston to the 026.
@drf255 and I have ordered one of these...... not sure why HL Supply show 2 rings, perhaps we get a spare?
I have tried to get some dimensions for this piston but had no luck.
@awol said he has one in his race saw but couldn't remember 100% what needed to be done.
I have stripped my 026 down and when the 246 piston shows up, I will bolt it in the 026 and do some measurements.
I am keen to hear peoples thoughts, ideas, concerns and advice on the subject.
If it wont work, the piston will make a nice paper weight on my office desk!
