I bought this a couple of years ago on eBay, only used it a few times and it always seemed a bit feeble and sounded a bit rough. Today I pulled it out of its corner and it wouldn't start, so time to give it a proper going over.
First things first, make sure nothing major is knackered, if so it's probably not worth the effort.
Removed the plug and laid it on the head, pulled it over and a good strong spark.
Removed the pull starter, put the compression tester on and spun it over with the drill, I got 120 psi on full throttle which sounds not too bad for such an old machine.
Fuel line looks OK and not perished. What I emptied out of the tank looked fairly grotty, so hopefully a clean and rebuild of the carb will have it running.
Last time I used it there were some nasty noises coming from the gearbox. The seller said it had been 'serviced' but this obviously didn't extend to replacing the manky old grease or the broken shims.
The nameplate is missing from the gearbox cover so I only found out what model it was once I started stripping it down.
The silencer is made of ally and comes apart for cleaning, but there are no gaskets between the two halves, or between the silencer and the port on the cylinder. None shown on the parts diagram either. Does it just rely on a good surface finish to seal it?
Cosmetically I'm not fussed about the missing nameplate but part of its function is to stop the grease weeping out of the far end of the bush the large gear runs in. The old plate was riveted on but there is the remains of some double-sided foam tape or similar as well, to seal it. Nobody has these for sale so I'll just cut up some 1mm ally sheet and make one.
Stihl have no mention of this model on their website, so no idea how old it is or what size engine etc. There are a few places still listing spares.
The lever that operates the brake band had corroded and seized its spindle, then stripped its pressed-in fit in the plastic handle. I managed to punch the spindle out, clean it up and re-attach the lever with Araldite.
Blades stripped and cleaned (they were stuck together solid with tree resin). They will need re-grinding - anything special needed for this, or will a flap disc / powerfile (on the bevelled edges) do the job?
What do people use to lube hedge trimmer blades? I've only ever had cheapy electric ones before, those got slathered with 3-in-1 after every use.
So the shopping list doesn't look too bad:
- Carb diaphragm kit
- Gearbox cover gasket
- Gearbox shims
- Filler cap (some numpty overtightened and cracked it)
Hopefully have it back together for next weekend.
