Cliff Ruggles:
I would replace them with new jets, and new metering rods. I quit using used jets decades ago, pretty rare to find a set that will not be worn some from the metering rods sliding in them for many years.
It will need different metering rods as well than the stock ones. I've built hundreds of those here and we use a lot of those for our custom electric choke front inlet units. They are a bit too lean on the primary side so we use a different jet/rod combo in them with perfect results.....Cliff
Hotrodssnova:
I will build it to the recipe #2, I forgot it listed the rod sizes.
Hotrodssnova:
I got the idle tubes out. The restriction measures out to .051. Now this is where I need some help. I have been all over the book and can't figure out where the idle down channel is.
Also, the small end of the idle tube that is necked down, is that what I want to enlarge? #2 is calling for an idle tube of .037 to .038.
77cruiser:
It's the restriction to the outside of the idle tube, about a 1/4 inch away. It's recessed a bit.
Hotrodssnova:
Thank you for the picture. I was assuming that was it, but, you know.
