044 hybrid build CFB style

[Canadian farm boy]

Snorkel grommet pushes on.
Throttle linkage installed.
When installing the linkage just squeeze the trigger and then push the linkage into place. It should just snap into position.

Air filter base can go on. When installing the base put the master control lever to the full choke position. The air filter mount can go on and gets secured with 2 m5 flange nuts.

First time I’ve seen double grub screws.
Hopefully it it can bleed vacuum off quick enough with both.

I've seen a bunch with two. One near the bottom, one at the end.

Yes, red ones make Stihl fans go ooh and aah. Black ones, not so much.

I've always found that the 044 oil pump was pretty anemic. A saw that has the potential to pull a longer bar also needs to oil it so I modified the oil pump for more output.

Start by knocking out the roll pin and then pull the adjuster out. Next the plunger can be pulled out. Be careful not to lose the spring and washers.

Here's the modified adjuster and plunger. Simply make the button smaller to allow for the longer stroke.
Modified plunger. All that needs to be done is to make the ramp angle steeper.

All back together again.

When modifying the adjuster and plunger you can use a small cut off wheel in a dremmel tool. Personally I use a cylindrical diamond burr.
The smoother you can get the surfaces the better.

Because this saw will be a hybrid the top cover needs to be clearanced for the 046 cylinder.
First picture is before. Second picture is after. I like to add some foil tape to the underside of the cover to help insulate it from the muffler. Nobody likes burnt plastics.

@Canadian farm boy
Are you gonna show the cylinder flange before and after clearancing?
I’ve got after pics if you need

I knew something like that was coming

I think the earliest 044’s have a black lever then they switched to red then black again.

Pretty sure I have before and after clearancing pictures. Thanks brutha. If not, I'll tag you in

He is right about the lever colors. Early saws (SN 120******) were black lever, then a run of red lever going into early 12 mm, then back to black.

The reason Stihl fans often ooohhh over the red lever saws is they generally correspond with some of the best running slant fin jugs that were on these saws. They don't always run stronger, but on average they do.

Most were 10 mm, but some of the early 12s ran very strong also.

This is the muffler mod I like to do. This started out as a 046 muffler. I drilled out the spot welds and removed the baffle. I personally prefer the 046 muffler over the 044 because of the shape and size of the factory deflector. No spark screens in this muffler mod.
