I've done that before. Not much there to "rebuild" fortunately. Tuning sans-dyno and O2 gauge is simple. Consult carb's manual for procedures. If it doesn't run great as-is the first variable you'll want on hand is the step-up spring assortment. If the buddy is using a mild cam and displacement of 350 CID or less, the stock config is a winner most of the time. Mine is 750CFM and cruise mode was very lean on my cam, 2 jet sizes and different needles. You will need the table in the manual (available online) for making jetting changes. I did not make it as far as the secondaries, WOT was OK for me so no change. Pump shot was fine as well. Idle screws on mine like to be out 2.5 turns, doesn't like 3 or 2. Yours should be similar, Q-Jets use 5 turns as start point but thats no good on these. However those step up springs work in Q-Jets!
Dad has a down tree waiting on me. Man I hope it ain't a pile like that diddlevine bunnywhip pic bcuz wedge n sledge after 16" electric. Nifty! Not near as hot here but plenty muggy of late.
Almost got all my injury and wreck papers done. I used the long rainy weekend for it, just now to a point where I can look at any of that stuff and not get mad. Spent like 20 hrs on forms and such learning new printer and all. Then another that long at one sitting, writing out the entire experience and trying to edit out all the personality so its all relevant. Harder chore than a guy might think. I know I got 3 meals and sleeps in but its kind of a blur. Paperwork looks good though, lol
Work was kinda a circus today... I started a couple days' gentle and well documented teardown of the blue/white 67 Ford pickup. Its not too shabby but sure shows it's age. I'm just glad they pressure washed the majority of the moss off it beforehand and kinda scraped the twig layer off the top of that ancient mill.
