Hi guys,

At my other home, I have an older Sears chain saw. I think it has an 18 or 21" blade. What type engines does Sears use, what size might this be, and are they any good to convert? This saw is probably about 10 years old or so, in case they have changed engine suppliers in that time.

Thanks,

Ive got a couple of older 2.0 cu in craftsman saws. Im not sure who made them back then. I havent gotten around to stripping them down yet to find any clues. I think the newer ones are Poulans.

i have a 12 year old sears 18 inch saw, ready to be put into some thing, car or plane, ive been wondering the same thing, dad says he rembers having carb problems,
and when we ran it, it would all of a sudden go rich and wouldnt pick up rpm for crap.
if i could fix the problem i would love to put it into some thing.

Hi,

It sounds like he had a problem in the carb that could have been fixed. Mine ran really well, just had problems with the oiler. At any rate, if the carb is inherently problematic it is easy to change and everyone does it all the time. Here is a carb website for you to browse: http://wem.walbro.com/walbro/family.asp. (It's not like changing a carb on a car; the hi and low jets are adjustable making it easy to change to a different carb and just adjust it to what your engine wants.)

This saw is at my other home in the states so I don't have access to it and won't for a while. Kind of a bummer nobody answered me here with any info. If this old saw won't work I'll probably shop for something else 'cause I want to get more into gassers, but unless someone answers me here I'll just have to wait.

Take care,

Your original post was on 5/26. Give everyone a chance ok? Now, Poulan has been making Sears stuff for a number of years now. If it's a Poulan, it'll most likely be a 38 to 46cc by the bar length you've given. Sears did have some real junk saws ( one of them had an auto sharpening deal on it, blew apart after 6 tries!). If you post some pics (yes I know you're where the sun is brightly shining, obviously NOT in NJ) someone else might have more info.

Ill try to get a pic of mine tomorrow and we will see if it looks like yours. Im not sure how old mine is, all I know is its a 2.0 cu in.

Also anything that is free or cheap is worth a try. It doesnt matter if someone else has done a conversion on it or not. You never you might end up with a nice motor

Hi,

Sorry if I got impatient. I'm new to this forum and the last few posts I did got responses so quickly that I guess I got spoiled.

My saw is reddish orange, and it seems to me it might say 3.7 on it so it could be 60cc. I'm thinking it could be 14 years old the more I think about it. The automatic sharpener never worked worth a darn, and the oiler gave me lots of problems too. But I did cut a good bit of wood with it and the engine ran very well.

The problem is I'm presently at my full time home in Mexico, and I only make it up north to my other home where the saw is occasionally. I'll check it out next time I get up there; was just wondering if anyone knew about these saws in the meantime. (For my evil planning purposes.... ya know?)

Thanks,

Well if you're not going to use the saw to cut wood..............then go for it! Many of the bigger saws that have the case as part of the engine have been converted and run very well. If you can get to a Sears store with the model# they may have a parts breakdown you can look at. Then you'll know if the engine is part of the case. Poulan's web site has current model parts breakdowns for their saws.
