Hi everyone
I'm trying to understand as much as possible about small engines modifications I could do .
But I found many different opinions about how modifications will affect performances
So that's a leaning curve prior to get a kit saw maybe next year if everything goes well.
I have a cheap grass trimmer I got for free which needs some work on it , but I can use it to practicing .
Reducing the squish
Someone say it
Increases compression
Decreases maximum RPMs
Increases torque
Increases power
Someothers say it
Increases compression
Increases RPMs
Decreases torque
Your opinion about?
Muffler mod (60% final opening respect exhaust port)
That actually worked well on my jonsered
Allows to keep the engine cooler
Makes it rev up faster
Makes easier to adjust the carb (easier to hear when the engine starts fourstroking )
It should allow to move more air inside the engine so more fuel can be introduced , and it should increase RPMs
If someone here has experience about I would like to know your opinion .
Thanks for the help
