Hello all I'm back, it's been a while but I'm OK now.
 I still have not finished my engine project but it's back in progress now and getting close to needing the carb done again.
 I did pick an older carb that I might use but that's for later.
 It's good to read up on the projects and posts that are here, as well as all the tech stuff.
 Till next time,   Kenn

Hello again
I have a 72 C10 that I put a 355 in. It has a comp XE 268 H cam, 202 intakes and a performer on top so its just a mild rebuild,
The carb that I was trying to set up was;   17086047
I was having fuel delivery problems during set up that caused me to rebuild the engine.
During the rebuild I was given carb;      7041208
I plan on rebuilding one of these carbs but would like some help deciding which one.
I will be buying the kit here like the last time and using recipe 1 this time, unless that will be to lean for this set up.
thank you for the help.  kenn

myself i would stick with the newer carb (unless ite been butchered ) i dont like the old castings you have to be so careful with the plugs etc. i think the top of receipe 1 will work for most of it but i think your going to have to go to at least 2 for the idle. .what kind of vacumn and compression do you have . that will make a big difference . fwiw

Hello
I don't think I did any damage the last time I rebuilt the newer one and it's probably close as it is. I do have notes as to final sizes and I did install bushings and sealed the bottom plugs. All will be checked at tear down.
Thanks    kenn

Hi all.
I checked my notes and I have 16" vac and about 9.2 comp.

I took apart the older carb and found that there are some differences in the two of them.
I haven't measured anything but it looks like it's only had the parts changed. The plugs look stock and nothing else looks like its been touched.
I guess maybe I should stick with the newer one. That's the one I decided on in the very beginning of this journey down carb rebuild road.
