Getting these old tools going

[Keitai]

Just bought these two tools at local auction £62 each. The hedgcutter doesn't start and the blower works but goes off when left on tick over. They are unclaimed stolen tools from police station. I'm guessing the petrol is stale? Anything else I should do to get them going ?

Not used to the buttons/choke etc on hedgcutter, any advice ?

Shall I get a service kit and service them both?

The first thing you do with any two stroke unknown engine is to check for compression.
Pull the recoil starter and you should feel resistance as the engine cranks with a pop - pop sound.
If there is compression it will run again, so dump the old fuel and refill with fresh 50:1 mixture.
Post back for more excitement!

They both pull with resistance.

Which is the choke , do I put lever on left or right when starting? (In pix)

What about other knows?

 

[Burnerman]

Choke lever, move to the left for ON.....the symbol designates a tube that is blocked by a flap.
LA is the idle screw, HL is the main mixture screw. That one may only turn 3/4 of a revolution, depending on the age of the machine.

Should I fiddle with LA or HL?

 

[Burnerman]

No, not yet....let’s see if the engine will start!
Those engines seem remarkably clean......give them a good chance by checking the air cleaner foam, and cleaning the spark plug first.
Can you see any primer bulbs on the carburettors? The blower definitely has one, not sure about the hedger.

I should have said....Stihl screws are TX 27 on older stuff, TX 20 on some of the newer gear.

Put the strimmer head into combi unit but it's not strimmer head is not turning. I just screwed it on. Have I done anything obviously wrong? How do you take the head off out of interest?

The blower which started the day before I bought it the cord now doesn't work, I took case off and the metal coil pinged off how can I repair it?

Okeydokey, a bit at a time!

Strimmer wise (actually it's a brushcutter....genuine strimmers have a curved shaft and a flexible drive shaft cable. (I know this is a combi tool though).
Take the allen screw out, and see if the drive shaft is actually spinning. These machines have a centrifugal clutch so the engine has to be running reasonably fast for this to happen.
At the same time, see that the drive shaft is long enough to engage with the strimmer head......is it a Stihl one? Also check that when you manually turn the head, the part that engages with the drive shaft is turning too.
To expose the strimmer line, squeeze the white lugs inwards to release the spool outer cover.

The blower ( an elderly BG 55 or something?)
If both ends of the spring are whole, you'll need to rewind the spring into a tight coil and then engage it in the recoil unit....that's on the plastic cover, not the engine. You can then engage the starting pawl and it's retaining spring.
Forget about the starting rope for now - that can be rewound after....the rope sits in that notch as you wind the unit to tension the spring.
Horrible jobs I agree but we've all been there!
Maybe the springs are available in a pre wound cassette - I don't know.

Have fun!
