W/NG Carburettor

Post by simon.holyfield »

Folks,

I swapped my float bowl to the nearside of the carburetter. I expected it to be a cranked float bowl, and for it to end up vertical; actually it's not cranked at all and is still not vertical. Is this normal?

There may be a prize for the most inventive suggestion for the loop on the tappet cover!

Chaps, I now have a 15 degree Amal 1J float bowl. Can you advise what the float height should be set to please?
cheers

The original float needle only has one groove and the mixing chamber nut you have at the bottom of the main carb body is the correct one also. Barring a lot of wear it will be OK. The tickler should hit the float about 1/2 way depressed. Nev

According to the parts lists, this 1J Amal float bowl is correct for all but the very earliest W/NGs:

Secondly, it looks like the pipe attaches directly to the bottom of the float bowl using a nut & nipple, rather than a banjo. Is this right? The banjo appears to be for the very earliest top feed float bowls, Amal 2N?

Simon, as far as I know thats all correct. The fuel pipe on the carb. of my W/NG is also atached directly on the bottom end of the float bowl with a nut and a nipple. If you want I can post a photograph tomorrow.
Regards, Paul

You can still buy the bowls bare or complete, new. I think SOME W/NG's had top feeding bowls. Most seem otherwise with a straight nut and nipple with a bent pipe. I don't know what exact shape they were. I'd guess a curly bit half way down ( a coupla turns at right angle and a "U" bend at the bottom, similar to 30's models. I have to make some so I'd like to know. Mine currently have a piece of fuel line rubber with copper pipe ends. Nev
