Shonky new Dellorto choke plungers

Yeah, understand that Piet.  My original problem was not so much the quality of the part but the fact that I couldn't fit my new Venhill-made choke cables.  Anyway, all good now.

Reggie,

I've fitted dozens without the slightest issue.  

Reckon as long as the rubber seals the choke orifice, all is well.  Don't see much of the intake air taking a detour through the choke passage because of the "not so nice" plungers...

Piet,

Probably ok for a daily runner, but I fear the problems may occur down the years when bikes are left for a while. Most of the triples sold on ebay recently were purchased a few years back and left for a while before being sold.  Brass in the carb casting is pretty neutral, so would be fine. That thinly plated piece of scrap may end up having to be drilled out one day.

There was a good reason why all the inserts in the carbs were brass....seems the factory has forgotten.

cheers

Time will tell, Pete.

Think I'll have to sacrifice one and cut it up, just to see what it's made of...

That would be interesting Piet....  Hard to tell by sight though. There were some nasty zinc alloys in the 50s & 60s that just spontaneously degraded. I just hope we are not seeing the reappearance of them being made in the far east.  Had a set of cutters break and go straight through the palm of my hand....the metallurgy was so bad, you could see the crystalline structure.  Dug the box out (they were almost new, so I still had it in the bin) - they were made in the east  ::)

Thanks for sacrificing one to check them out (bigthumb)
