My buddy picked this up for me, he knows I love old homelites. I pressure washed it and checked for spark. It has tons of compression, hangs by the rope real nice. I was just curious if anyone could decode the serial number for me and identify when this saw was made. I plan on taking apart the carb for a good cleaning and inspection this week and replacing the fuel lines and filter. Hope to have it running this weekend. The bar is in good shape and the chain as well. I have a feeling this thing sat unused for a long time.

Serial number is 1411584, kind of hard to see in the picture.

The day that the old archives are discovered that tells how to decode a 6 or 7 digit serial number will be declared a national holiday on HOH! Until then, thankfully we have chainsawlady's sales records to get us close.

Well I had some time time to take the carb apart and clean it tonight after work. Now I have a couple questions. I removed the hi and low speed adjustment screws before removing the carb. The holes that they screw into both seem to have a bit of an o-ring seal. The two seals didn't look identical which makes me wonder if I should just push a nice fresh oring in each hole to prevent any air from leaking past the mixture screws. Or if they are some special kind of o-ring. Next question is about the fuel filter. Can I use any old weighted fuel filter that I can source from my local chainsaw repair shop or is the something special about the original style filter? Lastly, I rigged up a small fuel bottle like an IV bag to provide clean fuel just for the sake of hearing it run. Unfortunately it didn't run without the choke on or just barely off choke. I believe this is either due to an air leak on the mixture screws because of the poor seals or that I was just way of base on my initial adjustment of said screws. I just did a baseline setting of 1.5 turns out from bottomed, is that a good starting point on these carbs? I'll attache a couple pics for reference.

1.5 turns open should be plenty to run just fine. The o-rings on the mixture needles won't be causing all (or most) of what you are experiencing. I'd check the height of the fuel inlet arm and make sure the inlet needle isn't swollen shut.

Similar to setting float height on a regular bowl type carb?

These Tilly carbs seem to like to have the needle flush with the inner part of the fuel inlet area. They aren't usually a problem unless someone without proper knowledge tries to adjust one. The swollen needle tip (if it's got a rubber tip) is much more common. Ethanol or carburetor cleaner will do this.

Seems like the needle is hard plastic. Not swollen. Moves great.heres a few pics of how it sits. I replaced the fuel lines and filter. Just doesnt seem to pull fuel.

Well that looks about right. Did you have the fuel turret off to check the inlet spring?

This one doesnt have the plastic fuel turret on the bottom it's a cast aluminum turret that comes into the side of the plate that screws to the bottom of the carb body. Hope that makes sense.
I took everything apart again to make sure I didn't miss any specks of dirt or varnish. And then put it all back together. It runs better and pulls fuel now but still not right. It will run on the choke for a while and then partial choke but never without choke. It starts to lean out. I pulled the carb off and disassembled again. Its gonna soak in my carb cleaner solution overnight.
Tomorrow I will try again. If that doesnt do the trick I will order a carb kit that includes Welch plugs. Hopefully I don't have to go that route. It seems like all my gaskets and diaphragm in nice and pliable but you never know.
Thanks for the pointers, I'll let you know what I find out.

Maybe it's just me but, by the looks of the pics of your carb and needles....it looks like you have the Low and High speed needles swapped. The sharper tipped needle should be your high.

Also the order the gasket and diaphragm go down will have an effect on fuel brought in..make sure they go down in the right order..

Thanks guys.i made sure to take pictures as I was taking everything apart si that I didn't put Nything back in the wrong place. I re cleaned everything last night and put it all back together. I also switched the needles. By the time I got done last night it was way too late to be firing ut up. That thing will wake the dead.

Yes,they are quite loud with the stack "muffler" on them.Might as well run it with a straight pipe on it.Lol Ed

Well I have switched adjustment screws and that made it worse. I pressure tested the turret cover was leaking. I couldn't get it to stop. I ended up replacing the cork gasket with an oring which got rid of the leaks. But when I start it it will run on the choke for about 30 seconds. Then I back the choke to about half. It runs for another 30 seconds or so then with no choke it leans out and dies.
Any more ideas? Also I found a tillotson manual that shows the long slender adjustment screws as being the low side adjustment so I put it back that way.

Did you try running after switching the screws back? If they were wrong it definitely would not run good.
If its only running on choke thats indicative of fuel not wanting to get through (hence the lean condition requiring the choke). Will the saw run differently if you give it throttle?
