Stromberg oil usage

[Donkey]

Hi guys,

It appears that one of my carbs. is using more oil than the other. After a run out I have to top one up whist the other seems OK, though I'm not aware of a performance drop off.
Is the problem a worn needle "O" ring and if so, is it fairly easy to replace?

Thank in advance for any pearls of wisdom.

It is the 'o' ring on the needle adjuster. The adjusters are held in with those star washers, so you need to tap them out with a suitable drift.
New 'o' rings and star washers are available from Burlen.

Thanks for that.
Three questions follow, sorry.

What is a drift?

Burlen don't specify Stromberg, are SU parts compatible?

and finally, can a "non mechanic" attempt this?

Thanks again, when your passing drop in for a coffee.

You need the Zenith parts section. The part number for the O ring is B18532 (I think).

A drift is a suitable piece of material which can be used to push on something down a hole. In this case, I used a piece of brass rod and a small hammer.
The link above shows you how to do the job, it's not hard, just follow the instructions! The only goofus thing in there is that he doesn't know about Pozidriv screws!

That would make him American,

Not Many Posidrive screws over here,
I work for a German company that does use them occasionally, but most of my fellow service engineers don't even know how to identify them.

Even for phillips and flat blade screws I always buy german screwdrivers as they fit the german screws better (really!)

As always chaps most helpful, I will investigate.

And don't forget if you're passing, you're always welcome for a coffee.

Kind regards,

Brian

I am the author of the bowtie6 blog, I hope you all don't mind me taking the liberty to post a reply. Thank you Mark for adding the link and I am happy to know this has been helpful to you all. I don't normally reply to posts where my blog is mentioned but I've made an exception this time...

Nothing "goofus" at all "there"; for the record I know all too well the difference regarding Pozidriv screws. That is why I went out of my way to document that fact, otherwise it is very easy to bugger up the screw head. I have worked on numerous Triumphs (including Stags), Jaguars, Healeys, MG's, TVR's, a couple of Rippons, and others I can't remember and the great majority have had ruined Pozidriv heads. Hmmm...

Thank you Terry. Indeed I am American. And yes, we don't see many Pozidriv screws over here. This reminds me of a certain MG I worked on: I had to special order a set of Whitworth wrenches (bugger! sorry about that - Whitworth spanners), that come think about came in handy on a certain Triumph Bonneville too... Whitworth fasteners are also not used much over here.

Cheers!
