What's on your bench?

[Stump Shot]

Nice. Where did you find a case gasket? I've thought about finding one for my dad's L77 so if I ever need to go into it that far. Parts are getting hard to find

Found the gasket in the case. Cleaned up and re-used with some Hi-Tack for a little insurance. Yes, parts are hard to come by, so you have to mechanic as much as possible.

 

[ANewSawyer]

Unless it is something special, why not cut your own gasket, or reuse it with sealant, like stump shot said.

Thanks, I would make one if one couldn't be found. It's a occasional use saw that's more sentimental than it is used

Carb swap went great, my 42 loved the 346 carb.
Left to modd those two part:

Donor crank in, 2nd time was a charm, somehow managed to put it in backwards the first time. Doh!!! After I specifically told myself to pay attention, I blame being in a rush to press it in while the case was still hot, and old age. Recovered OK though.
Smoozed up the exhaust port after cleaning this KS "B" P&C . Ever so slowly coming together as 1973 meets 1983. Should be a real thumper.Haha

Original Piston and ring from donor saw, tank and cases were crushed so the logger did not wear it out. Which is unusual for where it came from. This logger's signature is whip a dead horse. Here he tried welding the bar studs to the case. Fence wire wrapped around saws holding starters on, duct tape everywhere, you name it, when this guy gets done, it's flat lined. I don't do any work for him, but get a lot of his old bones.

Ahh. Tanks are not easily found used yet. I have a cylinder for one sitting here.

I found one but, he wants just under what a new one is.

Currently rebuilding a smoked MS460. Poor saw...running lean, plugged air filter, and a dull chain.

MS250C that had been sitting for 3 years. New carb and full service. Ready to work again.

 

[jeepsnchainsaws]

Zip. Just had to make sure it still cut.

your 154 oil pump, is it big enough for the plastic worm gear?
If its not the big hole oil pump its just to Dremel out, its the same way we have to do on those older 42/242 also.

Was at the local Stihl shop getting a part and while I was there they handed the other fella in the shop this Echo and told him it was stuffed and he would be better off buying a new saw as it wasn't worth fixing.

I bailed him up in the carpark and offered to fix it for him.
He dropped it in my truck and we exchanged business cards.





He told me it has never run right and after a couple expensive trips to a couple local shops, it still wouldn't work.
Said it would run and just cut out mid cut, or would not idle properly.
Then it died completely and that's where I ended up with it.
He took it to 2 shops to see if it was fixable.
One charged him $30 to look at it and told him $600
The other charged him $44 to look at it and told him to buy a new saw.

Piston was scored up at exhaust port but the rest of it was like new so I figured it had been run lean and got hot.



A bit of cylinder porn. Quads that are located noticeably closer to the intake side.



I ordered a new piston from USA and when i checked it, the ring pins had been put on the wrong side.
This meant that part of the lower transfer port was blocked by the piston window. You can see they extend further towards the intake port (left) but the new piston was back to front.
I ground the intake side window out about 2 or 3mm so that it would feed the lowers properly.



I also found it had almost .060 squish with a gasket so it got a gasket delete to drop this to .040 and it ended up with 150psi

Got it all back together and it refused to run properly. It was either a bad air leak or bad fuel delivery.
The carb had been cleaned and rebuilt so I added some motoseal between the carb and the intake boot as it looked like it may not provide a good seal being very thin at the edges.

Off she went!
Runs like a new one!

Just need to cut some wood and get it nice and hot to fine tune it and make sure it is all good.

Its going to cost old mate $150 for my repair all up so he should be happy with that.

That's a good looking jug and slug.

The worm slid on and its head fit nicely into the pump but not touching, it oils, pump and worm came off a 254.
I may take it apart and now make sure the plastic has no strange wear, seems to be a lot of combinations (oiler /worm) for the saw.
I take it the worm is held tight from the pressure of tightening the clutch down. There is a large thin flat washer inside the clutch,,,not sure if its needed or not,, I put it in?? My 1st 154.
I could not believe how hard the old seal was.

Was cleaning up the rust off of a 394 muffler to get some paint on it last night. Was using one of those wire wheels that go in the drill...that thing works great...takes skin off in a hurry too!! Yowza

if it came from one 254 around 90-92 or newer you probleby has the big hole oil pump, even IPL only show 1 oil pump Husky had two different oil pumps.
The easiest way to seperate them is to study the oil channel, the one who is bolt on for plastic worm gear has a "H" on the channel.
We find the same issue with 42/242 also, they never thought about plastic worm gear when they started to produce them, and when they first came with a new worm gear Husky never came with a new part number

The drum has no notches to drive the gear, the gear has no slots for the notches,,so I guess I have the correct combo,, just luck,,,
I read where you need the drum and gear as a set with drive notches,,,on both
I dont have that but seems to work,,,,oils like the exon valdez

I'm 100% sure that you have the H pump, the one I sized up now had a diameter on 19.5mm, plastic worm gear is 19.0mm. The older oil pump was something around 17.0mm if I remember correct.
Btw, those 154/254, they are kinda famous in Scandinavia.
