BUG-ER.....
To fit my K&N filter i had to thread three holes on my carb, two i did by hand (pliers) as with the first one i used the drill and drilled the
hole bigger not threaded.
So... how can i rectify it, is putting some steel putty in the hole drill and re-thread a good path or is there a tried and tested way!
help!!!
Regards Matt

what about tapping it at the size you've drilled it (too big) and then fitting a helicoil to reduce the thread to what you want?
just a thought

how about just re-threading the larger hole and then just use a bigger threaded
screw
just another thought
I love Pinto's, even if i did get mine from P&O!

place a nut instead of thread??
make a pic sow we can advise better
i think that welding a nut or refilling with weld will be the best option saying that you have to be lucky with the material your carb is from..
else i would just go to the scrapyard...
many times a bad repair can be a week spot...
but in this case maybe it isn't
make a pic it judge better...

p.d. the best option sow far!!
make out of 2mm stainless a gasket! weld on its back the nut round of the nut place it in the hole drill the holes of the rest of the holes etc.
etc.
and you can screw!!
but it will depend a bit on distances...

Just fill the hole with DEVCON and re-drill it the correct size.

JP Weld, works wonders, can be drilled and tapped. I used it to repair a chunk out of a boat prop, still going strong. Regards Ray.

Drill and tap bigger.
Screw in an ally bolt with thread lock, e.g. bike bodywork bolt.
Flush off and drill and tap the right size.

Use a nut & bolt, or just use the two that are OK, ignore the third. I've only used two of the three bolt holes for a K&N on a TLD carb,
perfectly robust.

There was some low temp (blowtorch)alloy welding wire at a few of the shows. Can't recall the name but it certainly looked ideal for this job.
Flow it in and drill & retap again.

lumiweld/technoweld is the stuff.
it requires a fair bit of heat though - so you'd best strip the carb of any bits that can melt and do it onn top of a cooker tpo aboid
distorting the body.
apparently in the instructions I have, you can stick a bolt in the molten metal and have a threaded hole.
agian without pic of your problem, I cannot know for sure but to hold an air filter you don't need much strength so I would try this chemical
metal stuff - supposed to be able to drill & tap and is meant to be as strong as metal

I wouldn't even think of warming it to repair it, chance of making a small cock up into a big one!
They are about M6 size aren't they? few options, small bolt, nut and washers (plus loctite!) or a big self tapper and some loctite!
Its a bodge but then its not doing a lot!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I agree with NS Dev on this, so long as none of the repair will end up being drawn into the carb if it fails, nackering a whole lot more than just the
carbs!
