A month or so ago I bumped the side of the blower housing against the corner of my Johnny Bucket and the round Stihl logo badge came off. I looked at it, it had what appeared to be little plastic 3 attachment "dowels" that went into small holes in the housing, "simple fix"... Yeah, right!

I didn't think I needed to disassemble the recoil/intake side of things so I got out the hot glue gun and proceeded to put glue into the 3 small holes and pressed the logo back in place. "Nuthin' to it!" Until I tried to start the blower! The rope came out about 12" and felt very stiff, it would give a bit but then it would not recoil then it wouldn't go either way in or out.. "What now?"

After taking the housing off the starter there it was... Glue in the recoil spring! Silly me, wanting to have a decent gob of glue in the inside to keep the logo pins from coming back out again I "plain over glued it". The glue was in between the coils of the spring in several places... There was suprisingly little glue, but it was in the exact wrong places... AND it had been quite a while since I had retensioned a recoil spring and never on a Stihl blower. Cussing DOES too help! It keeps your eyeballs from bugging out and pushing your glasses off...

It's OK now though, lesson learned... again!:D.:D

Sorry for your pain!
I hate it when I try to fix something and screw-up 2 more things in the process!

I'll remember to use that hot glue sparingly. Since you had the cover off, did you put some more on the tabs inside?

Very little in life is more painful or frustrating than the "Self Inflicted Repair"

Glad it's all back together & working as it should.

Thanks for the tip. It's always a good reminder to everyone to share mistakes or didn't mean to do thats. I would have done it the same way you did.

That is a good tip, thanks for sharing.

My concern is, how hot does it get there? The hot glue can remelt with the engine heat and turn to a thin liquid. Then it can get to the insides more and then when it cools off, it will harden again.

Yeah, every once in a while Murphy's law kicks in. Though recoil starters are some of the most frustating of all things. Nothings worse than sinking a bunch of time into one only to find out after reassembly that something is still wrong. Easy to do, too.

"My concern is, how hot does it get there?"

So far the repair is good and the "badge" is still tight. It's on the intake air side so it's not very hot until you shut down and then it's still far enough away from the hot stuff to be OK.

"Since you had the cover off, did you put some more on the tabs inside?"

It didn't need any more. It had smeared itself right into a perfect "rivet" and then set up.

"It's always a good reminder to everyone to share mistakes or didn't mean to do thats. I would have done it the same way you did."

:D:D:D It's a darn good thing that J-B Weld doesn't come in a squirt tube! It's usually my first choice for this kind of stuff.:D

When I did the job I didn't realize how close the spring is to the inside of that area of the housing. In fact, that surface is what keeps the spring aligned on the outside so it's close enough to rub. Which may or may not have rubbed off the original ends of the badge pins. Even top notch brands have some "quesionable" assembly practices all in the name of cost control.

Sorry, my mistake, I didn´t explain enough. Pics where u can see, where the glue got in. It might be interesting to see, how he glued the decal... ! Or could the decal be glued extensive (decal directly to the cap). Just like to see, how it looks. :ok:
EDIT

BTW: I´ve a SH55, the older model.
