Husqvarna 51

[stinkbait]

I got this from a craigslist add that I saw this morning. Seems to be in good shape, just a little dirty and stained. The compression checked at 150psi. Cranks and runs good. I paid the guy $80 for it. I feel like I got a good deal. The only other husqvarna that I have owned was a 272xp. I don't know much about this model though.

The 51 is a good saw and probably my favorite 50cc saw, I have owned many and rebuilt several. The 51 is the little brother to the model 55 and the big brother to the model 50. $80 for a running 51 is not a bad deal at all.

I figured that I could clean it up a bit and play with it some. Then maybe sell it to someone who needs it. I might even port it if I keep it long enough.

I bought a new black top 51 back in 1992, my first new saw. It was my only saw for many years, I cut a lot of wood with it for sure. Its a Very well made, reliable saw, I still have it and it runs fine...

:agree2: The Husqvarna 51 is solid saw. I paid around $170.00 (a bit too much) for mine, but it was in Very Good Plus/Nearly New condition.

I started cleaning the 51 up last night and decided to widen the intake and exhaust ports since I had it down so far. I've been wanting to try out my new bits for a while anyway. I widened the intake and exhaust to 70% of the bore and didn't change any timing numbers or the transfers. This saw really needs the base of the cylinder turned down because it has a large squish of .050 without the base gasket. While I had the cylinder off I decarboned the piston and polished the crown. The saw cleaned up pretty well. The muffler was really restrictive, I thought, for such an old saw. I fixed that though. Here are the pics.

The saw is looking good. I have been told these saws respond well to porting so I am looking forward to some video or maybe even getting my hands on it one day. Seems that one of the weakest points in these saws is the intake system. The boot and impluse grommet are known for leaks and the carb bolts holes are easily stripped. Another member suggested to always start the carb bolts by hand before touching them with any kind of driver, makes sense to me and could save a lot of grief.

Both of my carb's screws' threads were full of plastic when I removed them. Upon reinstallation they wouldn't get tight. I have a box of junk plastic poulans that I found two screws in that were a little larger in diameter, and with deeper threads. I used those and they worked great. If they strip, I will probably be looking for a new piece of plastic. I don't know why they don't have a solid spacer like the 272xp, instead of all that plastic and crappy boot.

I love my 51. Had it since new (97). Would never get rid of it. Just love the size and how easy it is to move around. I'm looking for a 50/51 to do the 55 swap so I can have an excuse to have more of them!

I love my 51 black top with a 55 rancher top end it light and cuts like crazy

This one is a 97 as well. I have yet to cut with it though. I have only cranked it once when I bought it. I plan on playing with it this evening. I didn't get it back together until last night at 1:00am.

Well, the baby girl and my wife were sleeping. My wife allready hates chainsaws. Well, she doesn't hate the saws, she hates the time I spend with them. I sold six of them this winter, and when she found out she got mad. Go figure.

Drill the plate out, countersink the holes and install a pair of Stihl carb studs.

I bought one brand new in 1998 for 330 out the door. Just sold it a few months back. I am not into selling saw I keep em forever basically. Have what I need and run collect em too. Get attached to em ran that one for years, and held up like it was ne. All I ever did was replace the bar once, and normal mainteneance and one fuel line. One of the best 20in saws made ever. Even though I don't use that size saw anymore for what I do. I will always miss it.

 

[stinkbait]

I just finished running it for the first time. I think that it does pretty good. I think this saw wood make a decent firewood saw for the smaller stuff, around 10"-12". I will see if I can get my wife to make a video of me running it tomorrow.
