If it's 5/32 you may find a cheaper one than the one on the link as that was just the first one I looked at.

$8. for a plug you may as well spent a little more and get a complete carby if you can't find a cheap plug.

Thanks Max. I think you're right, it could be 5/32. Looks like that's the right sized welch plug, assuming the missing part is a welch plug. I've been asking over the internet, but getting mixed feedback. Few people say a welch plug, some say a check-valve nozzle, others say nothing should be there, possible because of its age (70s/80s era from my understanding)

I think It's probably better to just buy a cheap replacement and hopefully they kept the same design, lol.

Thanks AVB. Quite confusing when they have multiple versions in 1 diagram lol. I found this more specific diagram for the SRM-200DA

It doesn't mention a welch plug (or main nozzle), but it does have a 'nut' listing in the parts list *shrug* (no nut on mine).

Inly had one thing wrong, ordered a 25mm valve, they sent a 40mm and refunded the money without issues as soon as I notified them

Thanks Norm. If that's the case, I might give them a shot & see how it goes. At this stage I'm unsure if/what part was there, so may just grab a replacement anyway just in-case.

Anyone know what would happen if I were to run the trimmer without anything there (if there was suppose to be something there), assuming it would run?
