Carby Walbro Carb idling

[Fabian]

It appears to be a Walbro replica WT series, with a throat diameter of 14mm and a venturi diameter of around 12.5mm.
The carburettor is fitted with a choke and does not use a primer bulb system.
I have no idea what the model/serial number is, other than that it appears to be a WT replica.

Knock off wt-257 looks like. I like the throttle linkage setup. Very different from the two styles I'm familiar with.

You have the parts you need to convert the 813 to single feed. You will either need to tap a very small thread into the fuel outlet/ pulse hole on the carb body and use a small set screw, or a tiny bit of JB weld. Then use the diaphragm covers from your knock off to have a single feed. Or tap a return fitting into your tank.

Your very welcome!

And I need to know where to get that v stack with built in throttle cable holder, and the linkage arm on the throttle shaft. This is what I'm familiar with carb prep kit

I just looked real close at your cylinder head...
What the hell! There's two coils and three spark plugs!?!?!

Please elaborate or point me to where you have before.
