Tree Monkey MS462 - PART 2

[RI Chevy]

Nice!

Within a very narrow power band.
Outside of that range it starts to work against efficient scavenging.

yep. pipes are a hole nother suject

 

[RI Chevy]

Very scientific I guess. Gotta be a mathematician I guess.

 

[tree monkey]

Where did you gather the 8/1 ratio for the case?

well I used my brain.

lets say half the air going through the carb is mixed with fuel and goes in the case. half the air goes through the strato.
mixing the the two gives you 16/1 at least some air is lost out the muffler. so somewhere around 8/1 10/1

maybe you gots betterer math then me. either way it has to be richer then 14/1

This is why I have kids!!! I tell them, "There is nothing like a smart phone to make you look stupid"!

 

[Dub11]

time the cuts and tell me what you think

Where's your fluffer?

 

[Redfin]

Im not arguing. Im rackin it around my noodle also. If Im understanding correctly. You are saying this carb with the divider feeds roughly the same amount of fuel than a regular carb with no divider?

 

[tree monkey]

yes

you can ask or question any thing you want, we're hear to learn right

this is key to understanding engines. everyone keeps saying add more fuel to make more power, but you need 14 times more air then fuel, if you want more power you need more air.

look at direct injection, nothing but air in the cylinder until just before ignition.

the strato's push fresh air through the cylinder first to sweep out the spent exhaust, some fresh air is trapped in the cylinder. the fuel charge comes in late in the cycle. the fuel charge is richer then 14/1 and mixes with the fresh air to get 14/1. it doesn't mater where the air comes from, adding fuel is the easy part.

lets say we gut the strato. and the fuel mixes with the fresh air, the that would have been fresh air going through the strato now has fuel in it. that air never gets to the crankcase. that fuel would have gone in the case but now it's not. so now there is less fuel going in the case. less fuel=less oil=more heat=more wear.

just something to think about

Thinking a lot now, thanks Scott...I think lol

 

[tree monkey]

adding fuel is nothing more then jetting, getting air into the engine is the problem

 

[RI Chevy]

How about forced induction?

Agreed. Funny how different saws react to the same mod. That’s the fun I guess.

 

[redline4]

Do these have a single throttle blade/venturi or 2?

That be a pipe, kind of, in a way, sort of...lol

single

 

[redline4]

Is that the way Stihl does it on all and Husky uses 2?
Or, does that have nothing to do with the stratos, and is the X-torq deal?

The only huskie strato saw that uses a single butterfly is the 365/372 X-Torq if I recall correctly
