Stihl repairs and restoration thread

[JOEPRO]

Well no carb kit in the post today so I went ahead and removed the pot for a look see. Exhaust had to come off with it as the bolts were seized. Got them out with no damage by heating the flange with the pot secured in my vice.

Basically if it had if started it would have ran like a bag of nails as there is wear in the small end of the con rod and I don't like the feel of the big end either. So this may be a full rebuild job just checking the parts for the 48mm piston I have. Pot and piston look OK for re use but some light scuffing is visible and if going this far its really a restoration so I will put a new top end on it also.

! tip recycling shop ! youv'e got to jump through burning hoops just to get stuff in the tip here never mind take anything away , you'd think they'd be glad as they'd spend less getting rid of it . The waste system here is so poorly managed it's a joke and they wander why there's so much fly tipping ​

I liked the one in pelaw, Durham. They did let you buy stuff, I never asked the last time (about five years ago) went but I’m guessing they stopped it. In the 90s my parents would take me to get rid of rubbish and I’d buy rubbish to take home.
I’m tempted by some Stihl saws on the bay, 8 for 265! I know I shouldn’t! I buy too much broken stuff.

I think removal from the tip is now punishable by DEATH ! that is of course unless it's quiet and you know any of the tip nazi's who stash any thing of worth away for thier cronies

Few years ago I took some stuff to South shields recycling center, they sell refurbed white goods and such, but not sure how it works, maybe a charity.

I'm glad that are such places I suppose you just have to search them out , I hate throwing tronics in the bin . I but not the charity shops can no longer sell electrical gear , pat testing and legal and such stuff most goes back in the rubbish for the bin men

It doesn't want to start up. Seemed like a faint attempt at one point but overall dead. Fuel was coming out the back of the carb.

it is a Tillitson carb and I took it off as kit should be here today. The diaphragm looks stuffed on it.

So I guess that needs rebuilt first and try again. But there is a metallic noise from inside the engine. Crank bearings feel tight so I don't think it's an issue there. But maybe a small end bearing or it could be something making noise on the clutch side which will need further investigated.

dont look that bad to me but could be the pic

when doing a carb if the inside dont look bad i remove all the rubber bits and the pin and put in fresh fuel for 5 mins to wash it off most of the time unless its hard or realy guncked up it get it to a point that its running and then i dont mind spending cash to buy the carb kit

There are few Yt vids that would appear to say that anything over a 100 psi is just fine , I didn't make them mind if I have time tomorrow I think I'll put the compression tester on the old 400 and the 770 just for curiosity .

Well I did a quick compression on the stihl and the 770 ( I needed to change the filters and plug anyway ) the TS 400 came in at poorish

90 psi , although it still consistently starts 2nd or 3rd pull everytime and the K770

a good 130 psi ish , on the test hits 90 psi by the second pull .

thought when doing compession cheak full throttle and pull as meny times untill it stops this wrong then ?

It's a two stroke , four pulls and it's done two cycles , no matter how many times you carry on pulling it ain't going to get any better . Why full throttle , that's a new one to me . I'm no pro spanner man though so always willing to learn .

dont know just what i heard so all ways done it

 

[JOEPRO]

(Note I did not make any opinion on right or wrong way to do it)

 

[roblane65]

Very informative , I still don't get why full throttle when your testing the pressure in the top of cylinder ? the schrader valve I get '

 

[JOEPRO]

I ordered a quality Italian made crank for this TS350 and will go ahead and order the other parts for it now including the Stihl flywheel puller tool.



I sold some other stuff on ebay today that was lying around my garage so good timing.

just be carefull the max sort of moneys they seam to fetch is 150 great if your doing for your self for years worth of work

Yes that's the problem isn't it, the TS350's arent worth much. So all said and done including purchase price and the new full rebuild parts I'll be around about £150 into it. Which is top price for one. So my time is essentially free and I hope it pays off and I like the thing.

Could the throttle open possibly be to let in the maximum amount air on induction possibly to emulate being under load as such and result in a higher PSI reading . I'm going to do it again tomorrow throttle open and see what I get . although my comp tester is a standard petrol ( no schraeder valve )

only reason id prob not be keeping the one i got is parts and stuff dont seam easy to get for them as easy as the newer stuff

That's why you buy a second one for spares
I could sell the spare one for probably £50 max but if I need a stop switch or air filter housing etc it would cost me £20 maybe just for that so I'll just keep it.

There were 2no Stihl 08 chainsaws (same engine as these TS350s) locally for £90 yesterday as spares or repairs. I did not go for that as I really do not want more TS350 stuff around just now! No space for it all I collect too much other junk gold in my garages.

So I would rather rebuild this one and only have one TS350 to deal with.

 

[JOEPRO]

I went ahead and split the case as far as I could this morning. I welded up an M4 thread adaptor onto my slide hammer and that made quick work of extracting the very tight clutch spigot.





Later I will bag and label the bolts etc before I forget where they came from! And as soon as the Stihl flywheel removal tool arrives later next week I can complete the tear down and begin cleaning, blasting and spraying the parts. When it's this far apart no point not taking a little extra time and re painting the clams etc. If I get the engine itself restored and rebuilt over the next couple of weeks that would be a great start then if running properly etc I can complete the arm and guard restoration after.

75-80 psi hot or cold on the TS350.
Sounds a bit low but it runs
I've been messing around with heating oil this afternoon as we ran out of oil
No time for nice things.
