Definitely do them yourself. I sell complete Viton O ring kits as all yours will need replacing. Use the existing brass ware. There are guides in tricks and tips on the forum of how to bench sync and set float heights, there are vids on Facebook and we are all here to help with advice. You can send the to Gerben for a full recondition / overhaul but it's not cheap. Have a go, you have nothing to loose.

Hi amx1992

post look good, think i will try JB Weld Steel stick once i get to rebuilding them.

I stripped the carbs further tonight, just that one tank float pin to get out...grrrrrrrrrrr

Though they look they are just chucked in a cutlery draw, they are all in order ;D

I had a full set of 400 carbs with broken float posts, I used an m3 grub screw and made some posts on a lathe/mill

On my 750, I use a piece of plastic tubing as a mould into which I pressed steel putty.

I had to put a little extra above and below the join as I wasn't happy it was strong enough.

It worked and is still working 30,000km later.

I have used a piece of cut down / shaped  curtain rail  bracket  as source of nylon to repair  a gearshift detent spring mechanism on an imported Nissan. I used fast setting Araldite to sort of coat the finished item - part was not available except as a  complete modified gearshift lever at crazy price from Japan.The fix lasted a good 4 years plus and was ok when I sold the 4x4.

Since then I've used Araldite for lots of repairs though I would not use it on a Carb due to the fuel etc. It did worry me when I dismantled my 400/4 carbs - fortunately they were okay.

I love the inventiveness shown here to repair the broken posts.

great idea, I might just steak that. I don't have a lathe and probably the easiest way for me to do the repair

Go for it; all you need is a Dremel or similar to trim the post. But it occurred to me that I might have used Quick Steel and not Steel Putty; it’s quite a while back now. The products were made by Pratley down here.

I see you’re doing a 400F2!

The difference can be stunning! :) Good luck.

What you've done looks good.

I took the poorer man's route and had the chrome parts powder coated - not the rear mudguard, that was isopon :) It looks OK; not brilliant up close, but good from a distance.

Keep at it.
