Does anyone happen to know what size jet came default in the 2150 carb on my 77 F250? 400 engine, c-6 2wd, blah blah blah. and before anyone says to go look at this spot or that spot on the engine, I can't. I'm on the opposite side of the world from my truck right now. But I'm ordering a rebuild kit so I can work on the truck when I'm home on leave in two weeks. So, anybody?
Yeah, jets are tuning, not rebuilding. Things like accelerator pump cams, squirters and jets don't come in a refresh kit. That's part of the reason people dislike Holleys. They don't know how to tune them. They put a rebuild kit in it and wonder why it still has a flat spot or is still too rich.
I have a drawer full of such items. When you get back, let me know and I'll try to walk you through the tuning end of it.
well, I'm figuring I "might" have to do some tuning as well.... that well be seen after I've replaced the timing chain and got it timed right. then to rebuild the carb (pretty sure it's never been cleaned, much less rebuilt). So I'm fully expecting to have to try my hand at tuning as well.
