Setting up the new carb--pointers?
Cliff Ruggles:
Those are main airbleeds, and have nothing to do with idle fuel, or idle air.....Cliff
73 Z28:
From your pictures, it looks like your idle tube is missing, did you remove it?
F250 Restorer:
You must be referring to the top photo. At the time of the photo they were prob. out. I bought replacements from Cliff, and hopefully they are back in. That would have been a real goof, ah?
CLIFF, besides drilling the mix orifices, what should be the next step to make this idle right w/o the surging?
Thanks.
F250 Restorer:
Cliff, can you please help me with this carb. I was advised to plug the bypass holes in the t.body completely. Now you state it may need more bypass air and/or be lean. Where do I go from here? Please advise.
Cliff Ruggles:
Reading back thru the thread, it appears that you had high idle issues, and couldn't get the engine to idle down. Now you have "nozzle drip"? Sounds like it doesn't have enough idle fuel to the mixture screws for what you are doing.
I'd back the mixture screws out to see if you can get the idle to smooth out. If they have no effect I'd open up the idle tubes, or close down the idle airbleeds, or both. What size are the holes under the mixture screws?.....Cliff
