ms362c build for the 12 saws of Christmas

[jmssaws]

The Tillotson off my 034 I used on it has been sitting for a year dry and i know for a fact that it's been at least 23 years since it's been rebuilt cause I've owned it that long and my father in law gave it to me and he bought the saw new in 86 or so
It's hard to say how many years it's been or if it ever has been rebuilt.
E10 or leaded is all its ever ran
Are the carb kits junk now or what?

The Tillotson carb that was on that L77 has been sitting for 15 years and the kit looked good. I rebuilt it but kept every old part I took off it. China rubber is the culprit

The Tilly's got that plastic metering plate spacer.

The ones I have are HK43 "B" but I know and "A" exists and I'm not sure what the difference is between them.

Mike found out a lot of interesting things about carbs on this model. One was that it ran the best with the Bing Carb that had a smaller Venturi on it than the Zama. We thought it was the fuel delivery circuit and that it's possible that the same high tune rpm between the carbs may have resulted in different fuel delivery at "in the cut" rpm's.

If my memory serves me right, the Venturi on the Tilly 43 and the Zama for 036 were exactly the same when I measured them. The bing 038 carb has a square edge in the Venturi that matches the 038 boot and intake port. I may be wrong about the sizing, don't quote me on that.

The Walbro 199 has a lot of potential for the 036. It appears that swapping the shafts is all that would be needed. You'd get a bigger Venturi and an accelerator pump which should work great on this Stihl model. I haven't gotten around to trying the swap myself.

I stand corrected. The Tilly has a larger bore and Venturi than the Zama.

Both are much larger than the boot outlet though.

It may be the fuel delivery circuit that's more important than the bore. That's above my pay grade.

I ran it one last time before I shipped it out.
It's still a bit chunky on the low side but it's new. Only tuned to 14k.
It's shipping to you tomorrow @Stihlbro

 

[Stihlbro]

Awesome!!! Final anwer? No changes?

I'm jealous of your test wood. That would be cut to fireya wood lengths here.

I haven't changed anything in the cylinder,I changed the side outlet muffler to the other style that has the outlet in the front and tried a few different airfilters and there all to restrictive. Needs a metal screen type.

I did change the carb but that didn't change anything that I could tell.

So, you're not happy with it's performance? Or just trying for a little more?

Always try for a little more!!!

I wasn't happy with it,I've ported several of these lately and this one was missing something compared to the others and I couldn't find the problem until I noticed the other day that the ignition wasn't advancing so I changed the coil and presto it was fixed.
I changed the muffler just to see if it made a difference and I believe that it did pick up a little.

The airfilter is killing it,night and day difference without a filter.
Huge difference actually

Can't let it go?

Nah just been waiting for the holidays to be over.
I figure while it's here is might as well piddle.

Looks good Jason. Assuming the wood is similar, I think it runs better fat, looks very impressive.

The 034 supa showed up yesterday. Filled and oiled it up and put a 20th anniversary 20 in. bar and a tree eights chain on it.


Videos in a bit. Saw is real strong and feels good. Should make a excellent firewooder.

This evening, little warmer and a block of red oak.

I'm glad you got some better weather.
It's not a great looking old saw but worth the 10$ I paid for it at a yards alert.
It was scored but the problem was easy to find,the impulse line wasn't hooked up. Lol

That runs real nice.
