Trick kits have accelerator pump cams, squirter, gaskets for 4150 and 4160, vacuum springs, 30 and 50cc pumps, Basically 1 kit to fit just about every 4bbl. So you have to be very careful especially if your old gaskets don't live through coming apart.......some of the metering plate gaskets are very similar just a small hole here or there different, same goes for baseplate to main body gasket. Get the wrong ones in and the carb can run poorly. When you order a regular renews kit it's look up by model number so you only get parts for that model. A trick kit has a lot of parts most ppl won't use and is more than twice the cost
I saw the inflated pricing. I recently rebuilt a 650 spreadbore and the kit wasn't nearly as much. Just wasn't sure if you were able to "tweak" the carb with the trick kit to get more out of it.
yes , what ben said . looked up all three kits for a 4150 dbl pump carb , trick kit was $123.95 at summit , fast kit was $42.15 , renew kit was $40.11 . certain single pump 4160 style renew kits are cheaper . I keep a quick fuel basic 600 kit in stock ( about $19.00 ) and a quick fuel "dirt" 2bbl kit in stock ( about $23.00 ) and just add a couple gaskets , diaphragms , power valves etc as needed . the extra trick kit gaskets may never be used ( there are even some spreadbore gaskets included it looks like ) but the extra cams , nozzles , vac sec springs etc could be handy for tuning and may be cheaper than buying them individually . depends upon kit selection and your needs . figure about $10 each for nozzles , $5.00 each for pump cams if ordered separate .
