1120

thanks for the info on my saw. So the bad diaphram causes the gas to not move into the carb because the fuel pump is sucking air through the primer, I guess thats good and bad. Did they make that same carb with a choke or do need to look for a different one? and where do I get it any ideas?

What carb do you currently have on your 1120? From there I may be able to cross reference you a carb. I have in years past been able to use carbs from the newer P series saws that have choke plates if they are from the same series of the original carb. It is most likely a Tillotson HS series carb but that is not carved in stone as Walbro carbs were also used.

yes its a tillotson but it doesn't say hs or anything except an R in a circle that is assumed to be registered.

Your numbers would be on the side of the carb but I would suspect it to be the HS-16B if it is a Tillotson. There are 3 carbs similar with a manual choke , they are HS-211A, HS-211B and HS-214A and these were all used on Pioneer saws. There would also be many HS carbs used by all manufacturers that could be adapted to the 1120 by just swapping the shafts from your carb into another carb body. I do that all the time, all you need to find is a carb with a 33/64 venturi like the HS-16B that is in your saw.

O.k.

Thanks for all your help. I think I better stick with the easy to install Pioneers. if I can find one. I'm sure a lot of this stuff is easy once you see it or do it once. 33/64 venturi is way to much for me right now. I would guess thst it means 33 /64 sixth fourth of an inch and i understand the venturi principle but putting them all together is like reading a menu in Quebec city. You have an Idea of what your going to get but never exactly sure. Chances are it will be really good.however.

Any Ideas on where to purchase a hs 211a hs 211b or hs 214a ? Are there guys who have such things for sale?

There would be lots of used carbs out there that at most would need a carb kit. A small engine shop could check with Tillotson to se if there are any new ones still left sitting on shelves and of course there is eBay where there is always an assortment of carbs up for auction. Your understanding of the venturi size is correct and if you could find a Tillotson HS with a 9/19" venturi it would work but the throttle linkage would have to be modified to work with it, you will need to come up with a choke linkage anyway and it can be mounted in the hole where the primer pump now sits.I have made adapter plates that utilized the two bolt holes from the pump to mount it and a hole through the plate for the choke shaft to run through.

:hmm3grin2orange:

You do of course realize you have just presented with your first symptom of CAD...

:hmm3grin2orange:

Oh, I know....

Come to think of it, there was another large pioneer sitting in the shed I did not take. It was not in pristine condition, but I'm sure it runs good. I just thought, "What the heck am I going to do with a saw that big?" What was I thinking?!?!

Now I kinda want it. lol
 
One question...

How much oil is the chain oiler supposed to put out? It seems like mine puts out a bit more than it should. I wouldn't say it's excessive, but it's more than I think would be normal...

My only thought was, there wasn't much care about being "environmentaly friendy" or being "green" when it came to oil consumption when these saws were built, so maybe it's just fine?
 
Meke that 2 questions....

I have heard of a few guys that say it is unecessary to run 16:1 and that they run in the range of 40:1.

How many of you do this?

I'd hate to fry a perfectly good saw, but 16:1 IS pretty rich

I run not quite 50:1 in all of my saws (mybe 45:1). But you have to make sure you are using the "good stuff" Stihl fully synthetic and non-oxygenate fuel. Some newer fully synth oils say you can go 100:1 but I am not that daring...

If you own a chainsaw you cut down trees, not save trees :laugh:

The more oil the better in my book. I use husqvarna or motion-lotion (which I think comes from the same factory) very sticky. You want the oil to spray off the end a little when you pull trigger and hold it in one spot for a couple seconds IMHO.

only question left is: How long until you go back for it?

And the answer to your question is: get a big bar for it...
 
Thanks Brian. Sounds about right then.

I will invest in some good oil for it, so that this saw is around for many years to come.

One other though on fuel though, do you put any kind of stabilizer in saws that don't get much use?
