My turn at a 660

[I Know Something]

Thanks to Walt @afleetcommand for the tools and putting up with me in pm's. Matthew Olson for his bolt by bolt video's. Also a big thanks to all the posters in this community. I'm learning a ton. Fast.

Its finally together. The only OEM part swapping I've done is the crank bearings and seals. The flywheel side came with metal shavings. And after getting them out, it still had a spot it stopped in. So, both sides are gone. More to come.

I see why the plastic selector lever is replaced. That thing bends like crazy.

Is the rubber boot between the carb and the jug still an issue? I'm not planning to fire this up till next weekend. When it finally reaches above zero in temp.

Only other thing that's done is the 56mm top end and a popup piston. I wanted to do a base gasket delete. But, the piston ran into the top. And I have zero ability thus far to shave that.

Otherwise it was a blast to put together. I got a buddy that's been looking at them longer then I have and wants me to put his together. Lol. Game on!

I've have not had any problems with the intake boots that I have used so far but time will tell.

Mine just seemed really tight on the bottom against the ring installed compared to the top. Just seemed a bit odd. So, thought I would ask.

56mm popup?

Can you tell me more... I’ve got a bb hyway on my oem 660. I’ve been looking for a popup in the 56mm shape and size...

Things here in the uk are a little different than the USA.

Cheers

It comes out of Florida. So, I have no idea how England would work. Have somebody buy it and mail it?

HL Supply has them also, a little cheaper to boot. Don't know about shipping to the UK though.

 

[Wonkydonkey]

Cheers, I will look for a supplier near home. Postage gets expensive from USA

 

[I Know Something]

Yeah it does. I have a buddy from Diggers Rest Australia. We mail them things a few times of the year. Its pricey.

Will this cause a problem and what's the proper studs part number for the stud needed? My Stihl dealer and I got the wrong ones. And yes, the ones that came stripped putting the bar on. Not good.

 

[two4spooky]

My bet would be on https://www.hlsproparts.com/Stihl-bar-stud-set-fits-replaces-1138-664-2400-p/h70381.htm . List the OEM part # in description,1138 664 2400 .

Got it to start and run for about 2 minutes. Here is a very short video. Oiler works. For some reason I cant turn the adjustment screw. Itll get a new muffler last. For now. It's going to be a work saw.

Now it's time for a bar and chain and some cooperating weather.

Fattin it up a bit and bring down the idle but in ether case good job. And most likely the reason why you can't get the bar oiler to adjust is because the case needs to be clearanct from casting that will allow a small screwdriver to fit into the hole.

 

[I Know Something]

Could be. Its rectangular atm. It seems obvious. But, it's also my first time seeing one. So, I'm going to side with rookie status and hope that's right.

 

[I Know Something]

Checked the oiler adjusting hole. Cleaned it out. It's all good.

Did a squish band check. .028 to .029 all the way around. Might be why the popup piston hit it without the base gasket. Lol

Ok. Carb tore down. The screen was clean. And the metering lever looks level.

Got any carb manufacturers that are preferred?

I believe a wollbro carb kit will work.

 

[I Know Something]

I will "assume" a Walbro carb will just work better? Looking for ideas for after the upcoming cutting season.

Yes I've also used a tiliston on my first ms660 ran good but I felt it didn't make as much all around power like the walbro did vantery is smaller on the tiliston carb.

That bar cover looks like it is drilled for the 460 style studs, available both through Stihl and AM. I prefer them, they hold the bar better.

[MustangMike]

If you try to use these studs with a standard cover you will need to partly drill a larger hole to accommodate them.
