I got an 81 we run at a local track. It is a stock class and I'm looking to do some tuning on it. I seen a post about the weber 32/36 carb, wll this help out the stock motor? Also what is a good timing to run on a stock motor to get the max power from it? The car handles pretty goos the way it is now with the stock 13 tire's on it but looking to go to a 14 tire low profile to help with sidewall roll over. The rear has been moved 1 inch on left rear forward and has stiffer spring in rr and softer in lr.I do have spring rubbers in the rf. Sway bar in front unhooked off left front but am thinking of relocating it under the lf a arm, will this help with rf bite? Shock on the rf is relocated on a arm and there is some camber in both front tire's, just not sure on setting.Also thinking of going to a stiffer left rear shock to help with forward bite, what is a recommended shock? And the left rear rim is spaced out about an inch and a half from stock rim. Sorry for all the ? just looking for some good info on it. Thanks, Slowone.

THE 32-36 IS A REPLACEMENT CARB, IT IS A VERY GOOD LITTLE CARB ITS NOT MUCH BIGGER IN SIZE THAN WHAT YOU HAVE CFM WISE,IF YOU HAVE TO RUN A STOCK CARB THERE IS A LOT OF MODS THAT IMPROVE AIR AND FUEL,IF YOUR DIZZY HASN'T HAD THE TIMING ADVANCE BLOCKED OR WELDED YOU'LL NEVER GET THE TIMING RIGHT

Can you post the rules for your division?
Like rad15e posted, the 32/36 is a good replacement carb. I think you would be better off with a 5210 Holley - Weber with modifications, if you're running a stock intake, cam, and exhaust manifold.
As far as setup. Tire temps is the only way to really tell what the chassis is doing. You can get it close by the "seat of you pants" setup, but you can get it even better by studying tire temps.

Thanks guy's. We really don't have rule's set in place other than a stock class and a modified class. It's just a bunch of friend's who get together to have some fun. We run street tire's, with a little work done to them. I have raced karts for about 20 yrs and understand tire temp's but the track change's alot from the first outing to the last. We start racing at about 5pm and finish up at dark being that lights are not in place yet. I am thinking of overhauling the engine this winter and doing a few mods as well. Just looking for some advise before doing so. If you guy's are on facebook look for Tabitha Wilcher Phillips and friend us. We have a video of the track on our page. We are the beige 81 chevette.

Will the 5210 carb bolt straight up to the stock intake or will I need an adapter?

The 5210 is a factory carb from 1979 - 1980 or 81. I believe 81 was the year they switched to the computer controlled 6510. The 6510 is easily identified by the electrical harness coming out of the top center section of the bowl. The 5210 does not have that harness, and has a mechanical secondary.
If you have a 1979 - 1987 intake, then yes it will fit. 1976 - 1978 had a different intake for the 1 barrel carb.
There's several modifications that can be done to the 5210 to increase airflow, fuel flow, and overall performance. Let me know if you need one modified, i've done around 30 of the 5210's over the years.
