Has anyone owned or knows someone who has? What are people giving for these? I was going to but it for a back-up saw- if anything... Thanks guys!

The story from a dealer who was around when they were introduced goes like this: (BTW, he still has a shop on his farm @ 82 years old)
The 451E was the first Jonny to have .325 chain and was intended to be a professional limbing saw. It did not come with, nor was it drilled to accept a bucking spike. Sort of an early version of what market segment is now occupied by the 550XP and 2253 which should be here in a couple weeks. At the dealer meeting introducing this saw, they filled one up, taped the throttle wide open and let it run til it was out of gas. Then did it again. He said it never sold that well since is was priced about the same as a 621. The one I have was originally sold by him on Nov. 4, 1978 for $329.95. (I got it with the original owners manual and receipt.) It was a little low on compression, so I cleaned up the cylinder and put a new ring in it.
My own evaluation of this saw is that it's not the power that is the big deal. It's a good running 44cc closed port saw, but nothing spectacular. What must have been special at the time was how light this thing was and how well it handled. Keep in mind, we are talking mid 1970's here. So try and think of what else was on the market back then. As I've said a few times here, I think most Jonnys from that era were somewhat ahead of their time and can still be run today without feeling like you are running an older saw. And the 451 because of it's light weight is probably the best of all of them in that regard.
A 52E or 49SP is a better choice as a firewood saw, but the 451 is a special little saw just the same.

Very good info -Spike60! Thanks!
-
Isn't it basically a 52E or a 521E with a smaller top end? ???
-
Completely different chassis. About the only 2 parts they share are the muffler and clutch cover.
-
I have 5-10 of these and it came out as said as limbing saw of 44cc. There was two types of ignitions and not the strongest either of them.
It can be found with some different carbs but I think HK is most common.
This is same family as the 452 and 45 that was first out I believe. 452N came with nordfeller that was accessory only on 451.
452 had that swiveling bar system that engaged chain break same as 410 series.
50/51 was first out with .325 from factory in 1971/72

Thanks! ;D

Just picked up an 451 ev. Is this the same? Does anyone have a work shop manual for this saw.
-
The EV came with heated handles.
-
Oh yeah it did baby! I was really shocked I think this is the earliest saw I've heard of with heated handles. I also have a 630 with heated bars but obviously much newer.
I really want to get this old girl running. Really neat piece of history.
-
I believe Partner was first with heated handles, about a decade earlier - but that version was based on exaust gas, and not electrical.

I really liked the exhaust heated handles to top handle and rear handle with adjustable heat. Like them lot better then the kind on top handle only on XPG.

??? Both handles are electrically heated on the XPG, G and WH saws (and the corresponding Stihl and Dolmars).
What varies is if they also come with heated carbs.

My OE 346xpg rear handle part must have not been working. My heated carb part was clipped to run a 357 wabro carb.

Yes.

451 was out in 1976.
First Partner with heated handle was the R18, 1969.
First Jonsered with heated handles was likly 50/51 1971.
First Husqvarna with heated I think was 240SG 1973.

finally dug out the 451, it needed a piston and oddly I had a NOS piston for this saw. 8)
I wanted to share some pictures of the inside of the jug, Nothing special but very small. I plan on fueling it later. I need a on off switch, a muffler at some point in time and I bet a carb kit will be needed.
any way here is a link to the pics.

David, the cylinder looks clean. Does it use points? Or electronic

Guess what the E in 451E means.... ;)
-
Lol!!!!! Thanks...
-
Yep two piece electronic. I tried to run it. Ran with prime. But obviously has a carb prob. I think I may try a carb swap opposed to rebuilding the old Tilly hk12. Great news. It looks like the walbro hda 34. Matches up very well. I just need to figure something for the impulse. The hda 34 comes from the husky 42. The squish with the base gasket pulled was 55 thou. It has a 8 pin 325 sprocket on it. I'll get some more pics guys. It's kind of a neat old saw.
