Stihl 064/066/288 Saw Build

[Brewz]

Awesome, thanks J

Now for HHS buts to cut my squish

Cant find bits short enough, only 3" long

What do people use to fit in the top of the mandrel?

 

[jmssaws]

I cut a groove with a cutoff wheel and drive a cutter in it. Just use a peice long enough to cut the band, like a 1/2"

 

[jmssaws]

What numbers are you thinking?
What's the timing on your cylinder with a oem piston?

Also, the spikes are aftermarket, bent, welded, yuck!

I dont want big felling spikes on it.

Any recommendations?

The small factory 044 spikes should fit, but I find them to be pretty useless.

I found this in a different thread ... "the numbers are: 1117 664 0500 for the outer, and 1128 664 0500 for the inner.", but I'm not sure if those numbers are right.

I have the big 661 skeleton spikes on my 440 and my 064, and I really like them.

The cylinder measures 94/122/80

How much should I chop off?

Little as possible

From memory it will keep the ring safe between .060 and .070

J, when you say you make a slot with a cutoff wheel, do you mean a cutting disk in an angle grinder?

Yep

Brews, you can cut the hss to whatever length you need with a cutoff wheel as well

 

[Brewz]

I thought so, appreciate the help folks!

I am stripping it now, its VERY crusty!

That will make a PSP cringe

Carb is a BING 49
It has an interesting main jet!

Good or bad?

The other newer 064 I have stopped is running a walbro WJ 10A

Using a 288 piston in a high ex short bar saw in my opinion is not needed. Although you gain some port area with skirt width, why drop the jug just to raise the ex again?

You may be better off using a 660 piston and dropping the jug just far enough to cut a pop up. Keeping your transfers as tight as possible.

 

[Brewz]

Yeah, I have had a think about the short bar thing and being realistic, if this thing goes like the others that have been built, I will likely ditch my 066 as I wont want to use a heavier saw with less power.

Short bar removed from title.

 

[jmssaws]

It should be fast with any bar

Bing 49's are terrible, send it on over stateside! Lol

Rare and very good carb

The 288 just doesn't give you port width, there's more benefit
