over the rear axle,or were the rear drivers side seat used to be is a good spot.take a few washers tie it to a foot of string,swing it around,now take the string and make it a couple of inches long,swing it around.feel the differance?the futher behind the axle the weight is, the heavier the car THINKS the weight is.you can thank sir issac newton for that little bit of physics.speedway sells a really killer rochester,with holley jets for 250.00.hope that helps.

if you don't have the money to buy a good carb you can get a tap at a hobby store for gas powers r/c car spark plugs and use that to tap the holes and you can put in holley jets thats waht i would recomend. you can buy a whole set of jets from like 60-99 for somewhere around $30. i found a good deal on one of those speedway carbs myself haven't put it no yet but the price was right

I would be glad to help you in the carb dept. If you like, email me directly at kineticperformance@thedirtforum.com, or at dumholtz@claritas.com, or call me in the evenings at 607-277-6462.
I can save you money, time, and hassles with the Rochester 2G carb you are running, and gain you significant performance over ANY other 2bbl out there of that type.
Each of our carbs are custom-built for the particular application they are being used for, and no carb of ours has ever failed a tech inspection.
Hope I can help.
