Stihl repairs and restoration thread

[JOEPRO]

Another installment here. I sold my other MS201 and kept the newer mtronic one.

But it had started a squealing noise from the brake. I traced this to a broken part I'll call the "dogbone"!



Cleaned and reassembled



Then i remembered the saw Also doesn't turn off with the switch any more.

So on testing it, there was a break in a wire so I took the handle etc apart (bit of a puzzle on these) and installed a new wire.

Tested and working great again. Sharpened the chain so it's sitting ready for work next time I need it.

Not another one! Yes. This time a rough TS410 that I bought from fb marketplace about 8 months ago. Seller didn't mention the mount was snapped. I also tried to start it at the time and had no luck.

Fast forward to now and it's in my way in my garage. With the success of tig welding another TS410 today:



I decided to pull this one out too. Why won't it start. Has it got air? Wow look at the state of this



With spray it would fire up which was a first! A compression test showed it was 150 psi. So whilst rough looking it has the bones of a good saw for someone.

I stripped, ultrasonic cleaned and rebuilt the carb as I had a kit on the shelf.

In the morning I will tig weld the broken bracket on this saw and put it back together as is. I'll have to wait on a service kit to arrive before I can advertise the saw on FB.



It's rough looking as I said. And I won't be restoring it, can't restore them all! I'll have it running very well and serviced and advertise at a competitive price and someone will be glad of it. Better than breaking for parts and it sitting here forever in bits.

If you haven't lost count yet, and for completness - this is the other TS410 which I welded today. It was one I bought seized for £20


The seller had it all in bits. And had snapped a bit off in one of the head bolts then he gave up.



I sprayed in oil and heated the bolt from below with a torch until the oil was boiling. Then I turned it upside down and with a couple taps with a copper mallet the offending bit fell out



So I got it apart without destructive methods and the original cylinder and piston appear OK. The main bearings were seized solid.





This TS410 I am going to put a full rebuild kit in, including cylinder kit. And full service kit. It will be a really clean one and I'll also sell it locally to get it out of my way and some £ towards my front garage upgrades. Will have to wait on the parts to arrive to rebuild it.

Likely to take 2 or 3 weeks with them being shut iver xmas..

Do remember the valve cover gasket must be totally sealed as it's a 2 stroke sealed crankcase. So really I'd replace the gasket or leave it until you have the kit in hand

Yeah Im aware of that, looks like cork so no chance of reuse. I could likely make something suitable from O ring cord as that wont get excessively hot.

I have spare Stihl feeler gauges I could send you one in the post.

I also have spare 4 mix gasket kits. What's it for? I may have one here if its a km131 or BR600 line

Update I welded the rough TS410 "Parts saw" and turns out I had enough spare parts to build it back up to a good running saw. The rebuilt carb means it now runs fantastic - much better than it looks anyway! Will be sold off shortly and that's a parts saw that is in my way now headed for a new home all being well.

Are the housings you welded aluminium or magnesium?

Stihl engine housings are made from magnesium I believe and it was magnesium rods I used for the filler.

Ah I see. Can I ask what type of rod, like what grade/number? With the amount of small engine repairs Im doing atm it's likely I'll need to weld some mag housings at some point!

It says the type of magnesium alloy stihl use here https://blog.stihl.co.uk/magnesium-in-stihl-tools/

For the rods I purchased them from @hotponyshoes he may be able to help you out. (I don't have the original package to advise on what brand or grade they are)
