Started Asian 440 BB #4 Today

In the US?

I think @jacob j. knows more about exactly when.

My 046 starts with 135, had a d jug and dp muffler, got it from the original owner who bought it new.

Hemi chambered jugs can also have either a stepped or solid base.

Likely one is Mahle and one is Stihl.

Different saw... but I noticed several kinds of cylinders on 372xt we run. Newest one has mahle and the older one has a husky branded cylinder, which I think might be gillardoni but not sure. Couldn’t tell much if any difference between them. Interesting that change in cylinder manufacturers... I wonder why?

 

[MustangMike]

The lowest bid!

The lowest bid!

That’s my thoughts too

I got a call from my friend Harold's son Jesse today. Jesse recently purchased a house and needed a saw so he got one of the Asian 440 Big Bores I built and ported.

Jesse works for the NYS Highway Dept and runs various saws at work, but says none run like the one I built for him.

He was cutting some White Oak rounds with it, and he says he felt like he was in a cartoon, and every time he cut a round the saw looked up at him and said "Is that all ya got"!!!

I guess he likes it! Feels good to know the saw went to someone who appreciates it!

For my education.

What exactly gets changed out when you swap a 440 to a 460 jug? I'm going to assume you keep the carb and everything around it from the 440? I'm intrigued by this and I might have to find one somewhere.

I think,,, it’s a hybrid, just mod the cylinder to fit and 440 shroud a bit of timing advance then boom. Your saw roars but looks like a 440.
It’s the smaller case compression that gives it the ooomph. There are a few threads around.
I will edit this when I find mattG's thread. Just cos and for no other reason, he did a fine build with help from other fine guys from here

Edit: here ya go

Awesome! And thank you. I'll take a close look at it.

Not so fast … that describes a Big Bore kit.

For the Hybrid (460 cylinder on a 440 case) -

1) You must enlarge the bolt holes toward the middle to get it to bolt up (460 bolt holes are wider spaced).
2) You need to thin the base of the cylinder to get it to fit in the case (a little filing to the sides does it).
3) You need some spacers between the lower muffler and case bolts (a few washers will work).
4) On the HLS jug, a slight mod to the fins for the top cover to fit (the bulge where the plug wire is contacts). OEM clyinders may need more work.

Sorry I jumped in

[MustangMike]

Not a problem, I just don't want anyone to get blindsided.

 

[I Know Something]

Thanks. I would have been. I might be building one of these as a winter project. Maybe a 372XP as well. Getting my hands dirty and loving it.

See the pic Jeremy just posted to Big Bore 046 thread.

That’s my thoughts too

Part of EU law is when you put a product out for bid, you allow all EU countries to bid on the contract.

For these 440 kit saws (and Big Bores, etc), it is best to replace that upper left dampener with OEM, makes a big difference in reducing felt vibrations.

I also recently went back into my 440 BB #1 and improved the porting and advanced the timing more. (see pics/details) in "what's on your bench" thread.

Timing is now .030 off the key (was .020). Saw sounds good, but hopefully it will stop raining soon and I will put it in some wood!

Sounds great. Have a question about the flywheels are you running the farmertec one or did you change to the OEM Stihl??
