Stihl MS440 (2 slightly different saws)

Nice. Thanks Mike.

I wonder when they started using intelicarb, I am pretty sure my early 12 mm metal tag 044 has it. I will check again. I know it has a zama carb.

 

[RI Chevy]

Is there anything wrong with the intellicarbs? Is there an ultimate carb for these 044's?

 

[RI Chevy]

Here are a couple of videos of the Stock 440 running.

Saw tached out at 12800 in the first video. I bumped it up to 13000 after that.
Definitely needs more of something, but not bad.

 

[RI Chevy]

I was thinking just regular carbs. Seeing that it was only a 440.

 

[RI Chevy]

I think the intellicarbs have the snorkel type scoop on the top of the carbs.

 

[RI Chevy]

I might be confused. What are they called?

 

[dall]

you are right jeff walbro intellicarb the connect to the air filter housing to compensate when air filter clogs up

 

[RI Chevy]

OK. Thanks Dallas. Does Stihl or Walbro make a non-intellicarb for these 440's?

 

[dall]

zama carbs was on the 044 without the snorkel

 

[RI Chevy]

OK. Are they better, worse, or equal?

 

[dall]

i prefer the walbro for the bigger venturi but to each their own

 

[RI Chevy]

OK. Thanks. So the Walbro has a bigger venturi? In essence, a slightly bigger carb? More fuel flow?
I prefer Walbro myself as well.

In doing a little research here this morning, I have a question. If I have a carb that has the limiter tabs with the 3/4, 1/4 settings on the filter cover and remove the limiter tabs, Do I use the H1, L1 presets? I am just trying to get my 440 dialed in correctly. Do all 440's have the same carbs? Is the H1, L1 preset the standard with these saws?
Thanks for your patience with my stupid questions. LOL
I removed the limiters and went with the H3/4, L1/4 preset and had a little trouble starting. So I backed off on the LA until I got it running. When I tached out on high, I was only showing 12800. The manual shows 13500 for stock. It was 4 stroking pretty good at 12800 with H3/4 preset. But I just want to get this carb adjustment right.

You might have to back off the high. Lean it out some. I personally don't like mine four stroking like crazy. I run my stuff a touch leaner than some though. On certain saws anyway. I don't own any stihl though just my opinion.

 

[RI Chevy]

I got ya Jake. But I just was worried about the preset adjustments.
I did lean it a little to about 13000, but I just want to be sure I start out at the right adjustments and then dial it in from there. [emoji106]

If you have a good HD they're fine. If not a big pain. The zama seem to run better if they're modded. Just takes a little more work to do it. I wish the studs were angled different so we could use 660 or 385 carbs on them.

 

[RI Chevy]

Where should I start out though Mike?
Which presets?

 

[mdavlee]

1 and 1 probably. They can be half and half sometimes. Whatever it takes to get a good consistent tune.

 

[RI Chevy]

OK. Thanks. Am I better off at 12800, or should I get closer to the recommended 13500? My ear always errs towards being a little fatter. I am a conservative. Lol
