Cracked again.....
I did do some of the tests - pulling over to see if i can feel the bottom compression....
I felt nothing , but didnt really understand what i would or could feel ?

ANYWAY

The Stihl is now in the menders. They were aghast (or amused) at the number of tests itemized to fix this I had done.
The first thing they asked me was -  "am i ok if they need to buy a new carburetor  "
There is no doubt they think that is the area.

This saga will hopefully be solved soon. Will report.

Update:

The menders rang and some good news.....

They think on this I have bought the wrong coils ....
(Understandable as they were all Chinese stuff off ebay).
I was also told there are 3 types of coil for stihls and I
have the wrong one (even though the eBay part from China
Says it fits .... (not eBay fault)
This could explaind a lot if true.

My original carb is ok which is remarkable after my hacking it and doing
My lemon juice boiling clean ..... , compression good.

Coil 30£ genuine one.

Next week my beloved 2002 stihl strimmer could be back !
Will update

Calm yourselves,  calm calm calm .....

This very week we will know exactly why this machine wouod not start!

Reason is likely:
- possibly simply buying cheap parts , non standard.
The engineer is replacing coil,  cleaned my original carb
(That survived a full force smash to the ground from above my head
In dribbling rage). And replaced the snapped off choke lever
from second hand spares.

To get to this stage took me 2 years , countless hours
of testing, 2 non standard coils,  3 non standard carbs.


We can all await the joyous news to come soon

Success !!!! Its fixed !!!!!

got it back today from the shop. I am seriously impressed even though the fix was what they said (simply a coil)
and if one thinks about it now obvious !

Always fit genuine parts .....

Basically it boils down to the coil. I needed the correct genuine coil (3 possibilities of genuine coil) for my machine.
Clearly every coil i bought (cheap non genuine) clearly was not correct even though it said it would work on a fs55.
It sparked but these things are so tightly tuned it has to be right.

New coil - fitted
Some tweaks to my original carb (remember i had bought 3 others non genuine)
fuel lines that had perished.

Original coil - £25
Labour brought it up to over £100 with other parts but this strimmer is more than a strimmer - i have owned it since 2002.
I would have paid more.
(Unfortunately this bites into the RD restoration budget (sending stuff off to the shot blasters etc) so for another
year the RD remains a wreck. (I think i prefer it like it is. It has a tale to tell. Doesnt impact its running in any way )

All done - thanks for input.
Next project - Hayter 10/30 restoration. Need someone to teach me how to weld !
