It's as per this photo.
I've taken to loosening the bottom tri-lobe nut sufficiently to pull the spool far enough down to disengage the six lugs. I then turn it 60 degrees anti clockwise and pull on each of the two line ends to lengthen each by an inch or so. Repeat this far too often...
Thanks for your reply.
If I lock the circular part above the arbor with a drill bit through it into the hole below, do I just then put a spanner on the square section and turn? If so, is it CW or CCW to loosen? If I do manage to get it off, I take it I can look for a replacement arbor (e.g. a...
A further question if I may. What is the thread designation of the head end of the strimmer? I tried a M8 LH thread but the pitch was incorrect it seems as it bound up within a turn. Any help gratefully received.
Do you know the designation of the left hand thread on that, please? I'm looking for a replacement nylok nut, if possible (my strimmer is an SRM250 but the head looks the same).
Got the machine running now (a little intermittently at time) - thanks for all your help.
As you can see from the first set of photos, I have this sort of trimming head; yellow with six drive lugs on the spool.
Can anyone tell me how you are supposed to advance the line feed on these heads as...
Thanks for the heads-up. Unfortunately, they don't ship to the UK where I am.
Will take a look at European suppliers though. Nothing on ebay.co.uk...
Cheers
Forgive my ignorance but, in general, is it possible to replace a carb that is no longer available (in my case, a Walbro WA163) with a newer model with a bit of 'fettling' or once they're gone, they're gone? It seems such a shame to have to scrap a whole strimmer because the carb can't be gotten...
Thanks once again. Tried this this morning but it had absolutely no effect on the fuel level in the feed pipe - didn't budge a jot. I closed the choke, pulled the starter cord repeatedly and could see the level in feed pipe rising slowly so can tell that there is some connection between the carb...
Thanks once again. I have replaced all the diaphragms and gaskets in the carb along with the needle assembly. Sprayed carb cleaner everywhere down every visible hole while doing this and so am fairly sure it's as clean as it's going to be. So to draw the fuel up the feed pipe I need to run the...
