Has anyone out there done/found a good cross reference chart for the gas engines we want to convert? You know..like the Kioritz engine is used in Echo brand equipment, and Poulan and Sears/Craftsman chainsaws are basically the same saw...just different name brand.... I have seen reference to the Mustang 50 and Fuji 50?? Just what were most of todays 'model' engines originally used for?

Maybe we should have a collection of entries about the Ryobi 31 and the many other names of engines where it will be found?

In recent times, The name Ryobi has been aquired by MTD of Ohio and the different names have proliferated.

Enjoy,

My Ryobi conversion started life as a Lawn Boy. I bought it new in 1985. But it wasn't long before Ryan's were every where. They disappeared and Ryobi's showed up. But I think some of the Sears whackers are Ryobi's. There are some Toro's and Stihls that make you wonder? What about the Cub Cadet? That's a name that MTD has owned for years. Then there are the MTD names like Yard Man, Lawn Chief, Arnold, among others?

When you see an engine with a counter levered crankshaft, that is mounted upside down, with reed valve induction, and claims a capacity of between 30 and 32cc, it's probably a Ryobi?

Ryobi also has made a couple different four strokes... And they make a smaller two stroke? Cannot remember the size? seemed to be better made than the "31"?

There's another name associated with Ryobi and that's IDC. They were listed as the owners for many years.

Then there are the many models of the engines labeled as Ryobi's?

Enjoy,

Jim

My two ringed Ryobi was actually out of a Bolens trimmer. Bolens can be found at Lowes.

WD40...I mean w8ye: I am glad you placed all that data there. I was at a new Lowes store, and I bet I seen 6 Brands of equipment that I am sure had Ryobi 31cc engines. Thats a lot to pick from. Gonna have used parts every place you go before long!!! Thats good. Capt,n

Is there a posting of what 'name brand' hobby engines are actually made from? Example would be the Brisson 3.2 is actually a Kioritz I think. The BME 44 looks a lot like a Poulan. I am interested in the 40-60 cc sizes.

BME = echo
brisson= makita
fox = makita
makita = sachs-dolmar
poulan = electrolux
husky = electrolux


this might help a little

Ryobi produced 3 different "generations" of 4strokes. GEN1 and GEN2 differ outwardly only by GEN1's metal "oil pan" vs. GEN2's black plastic. Internally, GEN2 has a modified oil baffle system that improved inverted engine operation. GEN3 is a completely new design that incorporates two magnesium(?) clamshells that forms the integral crankcase & oil sump. It is used in Ryobi's PRO-grade weedwackers.

Ryobi's smaller 2stroke is 22.5cc and is of balanced support twin-BB design vs. the cantilevered Ryobi 31cc crank. Again, it is only used in PRO-grade weedies.

BTW, my newest twin-ring Ryobi 31 is also out of a Bolens weedie.

So the Brison 3.2 is from a Dolmar saw and the BME 44 is from an Echo (Kioritz) saw. Do I have that right?

KenLambert

My Feedback: (107)

yet that is it but the dolmar is now Makita

Taking all the previous inputs, I get something like this:

Kiortz = Echo
Poulan = Craftsman (Sears) -saws
Fiji 50 = Mustang 50
Zenoah = RedMax = Komatsu-Zenoah
Kalt 22 = older original Zenoah G23
Ryobi 31 = Bolens
Ryobi 31 = Troy Built
Ryobi 31 = MTD
Ryobi 31 = LawnBoy
Ryobi 31 = Ryan
Ryobi 31 = Yardman
Ryobi 31 = Lawn Cheif
Ryobi 31 = Arnold
Ryobi 31 = IDC
Ryobi 31 = Toro (questionable)
Ryobi 31 = Sears (questionable)
Stihl = Stihl
35cc Webra Bully = Husqvarna Parts(82-86)
3w 35 = Husqvarna Parts(82-86)
fpe 3.2 = Husqvarna saw (Rancher 50)
fpe 2.4 = Husky 40 something

Efco = unkown
Tilton = unknown

Homelite = unknown
McCulloch= unknown

Hobby Engine Brands:



BME = Echo = Kiortz
Brisson = Makita = Sachs-Dolmar
Fox = Makita
Makita = Sachs-Dolmar
Poulan = Electrolux
Husky = Electrolux
Jonsered = Electrolux
Partner = Electrolux
Brisson 3.2 = Sach-Dolmar (saw) = Makita

Robin = Fuji (4 stroke-weedwacker)
Sears = Briggs & Stration (4 stroke-weedwacker)

If there are corrections/additions to the above, let me know, and I'll edit them into this post.

The Ryobi 31 is not a Stihl, or vice-versa. Stihl makes its own engines.

I would be interested if someone has a list of the popular hobby engines that cross reference the saw make and model. We could then look for that saw to essentially have the same engine as the expensive hobby engine. I have a Dolmar, Husky, Echo dealer up the street so I have access to most of the popular saws that have been used for hobby engines.

mangolo

Where dose the Efco and Tilton fit in this list???,
The Efco 46 looks very much like the Poulan but is not the same engine

What is the source of the head on a DA50? Is it a special one-off type head?

cu. in.

Jonsered and Jonsereds = Electrolux. My understanding is that Electrolux owns both Husky and Jonsered(s). Also, my new Jonsered 2152 has a Husky engine in it.

Check the Jonsered "History" link below. Click on the two flags:

DA cast there own cylinders

brisson is sachs or makita not koritz

KenLambert

My Feedback: (107)

electrolux also owns poulan

LN-JET

Electrolux also owns Partner.
http://international.partner.se/
Here in Scandinavia Partner is a cheaper type of saw sold through hardware stores,
unlike Husquarna and Jonsered, that are sold by specialists.

Certainly cleared it up for me.

AnthonyH

My Feedback: (16)

That does clear up who owns who in the saw business, but it still does not answer my questions. What saw make/models are used to make the BME, Brison, FPE, etc. engines. I am interested in the 40-60cc engines. Example is BME 50cc = Echo 550 saw.

BME 44 =
Brison 3.2 =
Brison 2.4 =
FPE 2.4 =
FPE 3.2 =

I will fill in the answer when I get them.

Hello,
I am comverting a Echo CS-4400 which is a BME 44cc with mag. I ordered the carb adapter from BME and the hub from Pete at Wacker Engines. The correct NGK plug is from Advanced Auto. I had to make a coil mounting bracket, since the coil was mounted on the saw body. The new Echo CS-440 is a different motor. It dosen't look as good.

Regards,Dave
