Matchsticks dont work mate, believe me!!

[Yetanotherbike]

My first bike was a Yamaha RD200. As I recall the dyno starter was similar to a design Villiers patented many moons before. Starting was almost instant.

Not sure but I may have a homemade one of that special tool. Was it shaped like a flat letter U? You held the weights open and inserted the legs of the U into small holes in the weights?

[Bryanj]

Sort of Ken, my homemade one was made from braking rod and bent in a bit in middle of straight bits of U to give it some "springiness" mate.
Still got the Yamaha dti in box somewhere

While it is chilly,and windy I am sitting and planning ahead,

The tank has rust inside,

Looks intact, but I would like to remove/neutralise it, any advice for   doing that?

Next I have ordered a wheel  rim,so  into the unknown, having a go at wheel building, all the spokes and nipples have been loosened and  checked, will be stripping the brakes and overhauling lubricating the cams etc,

Advice welcome

Hi John, just seen this part of your post. I used white vinegar, fill tank to brim for a day or so, clean with presure washer. came out like new inside, just put some oil with diesel in the tank to stop any flash rust appearing.

You could try steaming it, wallpaper stripper ? If it's gummed on the pin, that can free it.

Or boil it in water in an old saucepan.

I would try and gently heat the carb with a hot air gun, being careful not to loosen the soldered parts on the brass float. Maybe fashion an old beer can to direct the heat away from the float?

Your tank looks good, wish I done that with mine 10 years ago instead of the sealer which is starting to lift now.

I think I'd try the more gentle hot water method first in an ultrasonic bath with some carb cleaner fluid added.
This could be followed by a good dose of carb cleaner on the pivot and then another hot bath. You'd have to really careful if using a naked flame with the solder on the float being so close by.

For lower risk heating I use one of Wendy's old hair driers.

Upgrades include a Bosch Paint stripping heat gun,
lastly my Plumbers Calor Gas Torch.

None of the above worked on the seized center stand pivot on my 400, I had to resort to a hack saw and impact tool.

Thanks for all the help


Another option

A Chinese copy of the carb is online at £25,

So it might be worth a punt to see how good it is,

But, no rush, a little later I shall be making carb broth,

Don't fancy the taste!!

John,

good luck with the Chinese carb, I've never had one yet that I've been able to make work properly on two stroke engines.

They're now in a box under my bench marked "junk".
