Not riled up in the slightest Mason.
You've not seen me riled up yet
I was merely friendly ribbing you with a few questions
You've read too far into MY post

OK lol. Anyway let’s carry on... no need to muddy Joe’s thread.

Just another miserable day outside. 90* with around 75% humidity. Good times

I hear ya, hate the humidity. We’re starting a heat wave here in south central PA. It’s nasty.

Same here in western PA. Extending my current shed so I dug the post holes and cemented the 4x4s today, started at 6:30 this morning to beat the worst of the heat. Don’t miss those years of this kind of heat working 2nd shift.

Yup, fug that. Anything over 85 is ridiculous in my book

I don't know much at all about carbs, but I will tell you that I have a CFB Hybrid, and we tried several carbs on it but could not get it to 4 stroke till we put one with a 70 jet on it (I believe it is a HD-14 if memory serves me right … the NLA ones for the heated handle saws).

Now I'm just guessing … and I've been known to be wrong with some of my guesses … but if I had to guess the Hp of my Hybrid I would say close to 8 +/-.

DEET's comments on the transfers is very intriguing. I think most folks tried to increase "case capacity" on the Hybrids, to be more like a 460, but he seems to have gone in the other direction. Very fascinating!

But both saws have carbs modified to increase flow … that says something right there. My carb is all stock.

I guess the thing I'm pondering now is do higher RPMs require less of a venture to pull the correct amount of fuel, or said another way, will a stock venture get "too rich" with higher PRMs and cut the performance short?

Mike, a larger Venturi is going to require more fuel because there’s less vacuum or signal coming through the carburetor, so a larger Venturi, Or flow enhanced carburetor mods will require more fuel, in the form of a jet to feed it

I think that’s why I had so much trouble with the RWJ4 on other saws with the divider out. It was set up lean and I couldn’t get the Solo rich enough so I went to a 390xp carb on it. Which gained 10% cut time. A modded Zama didn’t even feed it real good. Some were 3-4 turns out and 15.5-16k was all I could get it slowed down to

After dynos fixed any 3120 or 088 going on dyno
I find it odd 394 stoker has less hp than a 044/046 hybrid
Could results be ascuwe sensor going bad then finally fail ?

I've posted a 3120. Close to 4hp more and 3ftlb more than these hybrids

Not done any 394, or husky stroker.

The 661 stroker was +2hp and almost +2 ftlb over these hybrids.

The 395 that was the same hp, had about 1 ftlb more tq than these hybrids.

700 hp Indy car vs 700 hp pickup diesel
