Chainsaw Repair

Aftermarket carb? Sometimes you get bad ones. Strato carbs on these known issues.
Plug getting wet still after so called start off.

Coil could be issue too. So unless you have known good one to test. Does it still have spark even after the first try.

Worst case. Be pulling muffler for a look at front of piston and back of cylinder.  Could still happen out of sight on sides. A score with pinned ring.

Not really a saw you want to get a bunch a money in IMHO. Throw away type saw if you cant do it yourself to fix.

Husqvarna 50 Magnum with Partner 5000 plus piston cylinder

New thread from the old husky thread to save info. Guy in my FB CR group has one.

I questioned the use of the smaller white top 50 crankcases as seen in pic and SB.   Putting a partner 5000 topend on one of those. See specs.

I recall my white top 50 had the smaller cylinder base.  =  (Back in the 80's we were selling a Husqvarna 50 Magnum. This saw was  created in Charlotte, NC by the Husqvarna Distributor owned by Jim  Thompson, The guy that made Husqvarna as far as I'm concerned. They  brought in Partner 5000 cylinders and pistons and put them on 50 Rancher  (the old white top) saws. These saws were awesome. The first one I  received we got out of the box on Thursday and blew the competition out  of the water on Saturday at the Races. Back then we had Chainsaw  competition's on monthly bases. Husqvarna Sweden made them stop building  them in the states. We built some ourselves after they stopped. It was a  simple bolt on with no modifying at all. Someday I'll tell you more  about the old Husqvarna distributors that made Huqvarna what they are  today.)

I ask owner if they were marked in anyway. =  Yes, it was Husky Power out of Charlotte, NC doing it. A letter "M" was added to the serial number plate to the modified saws. I'll see if I can find mine....

Will share pic here of it when he post the saw.

Info from SB.

To go with what Corey was saying. Here is from the SB link posted here under files. = The differences between the model 50 S and 50 R are among other things that the displacement
is increased from 49 cm3 to 51 cm3 and that the SA-silencer is replaced.
Due to the changes above, the 50 Special has gone through a for each country new specific
testing procedure. This means that no 51 cm3 cylinders should be mounted on saws with
lower serial number than 9190006.
The 51 cm3 cylinder base does not fit the crankcases of older 50 R models.

The 51 cm3 cylinder base has the outer diameter of approx. 49,7 mm (the outer diameter
of the piston = 45 mm).
The 49 cm3 cylinder base has the outer diameter of approx. 47,9 mm (the outer diameter
of the piston = 44 mm)
The inner diameter of the new crankcase is approx. 50,5 mm (this crankcase is identified
with the improvement code F)
The inner diameter on the old crankcase is approx. 48,5 mm

CC added =  It was in the 1986 model when they went to the grey tops the cylinder changed but they used the same piston, then in 89’ the 50 specials used the 45mm 51 topends.There also was some late 1988’s i think that got the 45mm topends and labeled as 300th anny saws , last 8 weeks of 88’ production run if i remember right.

Was keeping this under my hat till new owner picked it up today.

Stihl 034 Super Magnum II. Done by that Washington dealer.

Hadn’t seen the 034 in one to date. 😎👍

Just in case someone else runs into this down the road. RK-23HS didnt come with the short needle for this carb.
I had to use the needle from RK-28HS kit. Only thing I found different between these 2 kits was the needle and pump diaphragm. 28 came with both needles.

Dealer said he sold 385's =  I just looked, I sold some 385s that were built 2009 week 26.

So that goes with some info earlier.
