Skil 1645

[Mtthwvn]

Hello everyone. This past summer I fixed a big craftsman rear tine tiller for somebody and in return he gave me a pickup truck of small outdoor power equipment. A few push mowers a gas powered edger a couple weed eaters and a bunch of chainsaws. Most of the saws are poulan/craftsmans with a couple homelites, an old mcculloch 10-10 automatic and the one I'm trying to get running right now; a skil 1645 type 4. I got the saw to run this evening by pouring a capfull of fuel into the carburetor, but it isn't pulling the fuel from the tank. I have no idea how old this saw is, much less how long it's been since it ran so I figured at a minimum ill have to rebuild the carb and add a fuel line to get it running.
I took the carb off and found it to be a Tillotson HS113A. I got on the Tillotson website and found out I need a RK-23HS rebuild kit. I was wondering if anyone knew of a good place to find a good rebuild kit for this carburetor. I seem to be having trouble finding a kit for this carb. I found one on eBay but I'm not sure of the seller and I usually don't like buying small parts like this online without knowing for sure. I did happen to find replacement carburetor a but they are pricey and I'm not wanting to drop 60 bucks into a saw that is probably not worth much more than that in running condition. Sorry for such a long post for a simple question.

For just diaphrams and gaskets look for DG-5-HS.

I have a SKill 1645/Power Machinery 340. But, not the strongest saw in that displacement range. Love the styling.

Thanks everyone for the quick replies. I will be ordering one of the kits for the carburetor and copying the specs Ethar posted.
Not happy to hear its not the most powerful saw... I was looking forward to seeing if this old girl would give my 044 a run for its money! I'm surprised at the weight of this saw as well... 13.75lbs...pretty light considering a 440 weighs 14.8. Ill try to post some pics whenever I get it back together.

Ive never had one..but most of the old saws cut slow...or people say the are "luggers" ! Saws have gained a lot of RPM's over the years

Yup, the P.M. and Pioneers were stylish back in the day. Sexy, sexy lookin' thing.

I got this one as a non-runner. All it needed was the starter serviced and the usual fuel system refurb.

With it being a 70cc I'm sure theres a way to get alil more oomph out of it. Never had one of these come across my bench so not sure how its designed. But alot of these older ones you can but a bigger carb open up the exhaust and sometimes do alil port work. Look at what has been done with the old Mac's some of them are world class racing saws. And yes these older saws may cut slower but most had gobs of torque.
