(doesnt need to be perfect if the insert is glued in).

Good old JB weld would be perfect if This route was taken

It is easy Kriss, next time you need to repair something non ferrous give it a go.. all you need is a few basic tools a blowtorch and a stainless wire brush 👍

@Macpherson have used the earlier alloys which didnt flow well , or the part distorted under heating , so may give this new one a try . K

Yep, on very small items and particularly pot metal like carb material much care  is needed not to melt the item your trying to repair.. previous experience of welding / brazing / soldering with oxy acetylene is definitely a big help even although for most of these small repairs you can get away with using a plumbers blowtorch.

 

Filling a hole like the problem the OP has is possibly the easiest application of this stuff but it's worth saying that the melted in material from the HTS rod is quite a bit harder than the original alloy so extra care is needed when drilling and tapping small repairs to avoid unexpected tool breakages.

 

I think that the main reason for lack of flow when doing any alloy weld / solder operations is a combination of surface contamination with oils, ie not even a fingerprint... oxidisation and minute ferrous particles hence the SS wire brush, cheers.

Hi, If this is into Mag alloy it could be a perfect candidate for a HTS 2000 repair without taking the engine apart.
 
I know this method has been rubbished on here before but totally wrongly imo, since finding this method a good few years ago I've managed to save many things that would have previously been unrepairable and scrap... it for sure works on magnesium alloy castings
 
And to the OP... it's readily available on ebay and if you thought it worth a go... cleanliness and following the instructions to the T is the key to a possible easy fix, any questions, just ask. cheers.
 
 

Thanks. That's really helpful. I'll check it out. [emoji106]
