Still have one MS440 That Big Dave did,,, that saw to this day 9 years later never fails to put a a smile on my face... good seeing u posting wigs!!!! oh and GFY,,, and give the gun totin monkey a good kick in the sack for me!!!!
GFY too my friend!!
I'm slowly getting back into the saw game. Between work and mowing last year, I just needed some time off.
I'll be sure to kick him square in the giblets next time I see him....
And these are my friends?
Wow.....just wow.
I'll throw the word COMPRESSION into the game.
No doubt, the highest power output from a charge will be accomplished by the highest compression it can handle before detonation occurs.
But compression builds heat, that's it purpose. Heat, parasitic strains due to higher compression, and detonation are an engine's worst enemy.
Different engine designs can handle different maximum compressions.
Squish band velocity and chamber design play a role.
So what have you guys done in the real world?
I'm running my 036 at 215 psi. It's the saw I've cut the most wood with. I've had zero issues with it at that level.
My last few 026's have been 240 psi with no issues to date.
I know Mopar and JMSsaws run 066's in the 240 range.
Compression can slow a single cylinder engine down though....
I'm thoroughly enjoying the discussion.
Very different from the AS, where if discuss something and there is a disagreement, the lynch mob comes after you.
I'm gonna post freely here. If I'm wrong, tell me why. That way I can learn.
I'm right there with you Al. Loving the atmosphere of this place. Respectful.....that's what it is.
So I've come to learn that "4 stroking" occurs when the mix is too rich to fire. So that combustion cycle goes unburned, and then it mixes with some exhaust days and ignites on the next cycle. If it takes 2 cycles, then it's "6 stroking".
I'm having a hard time understanding why an engine goes from 4 stroking with no load to 2 stroking under load.
You lay the chain into wood, so now you have resistance.
Does the motor suddenly have more chamber heat to burn the mix better?
What's actually happening?
I have no idea.......but, I have other stuff I wanna figure out that takes center stage.
