quick fuel slayer carb

[pacman350]

im new to the site shout out to everybody. my question is i recently put a new quick fuel slayer 600 on my car and it runs good revs good but when in park if you just hit da gas hard its almost like it will die down or cut out wih more of a sputter then pick back up really quick. but when in drive when mash the gas and pull off it almost wants to die down but once it picks up it fine while your on da gas after dat.
thanks in advance for your replies.

When u open the throttle quickly it takes in a great amoutn of air and there is not enough fuel because the squirter is too small. Check what number squirter u have and chenge it to the next bigger one. The go in incruments of 3. So if u have a 25 try a 28 and so on. U will have to adjust yer acc. pump overide as well.

Just a thought here .... but why does it matter how it responds when its in PARK :| If it performs well while driving, I would consider it to be tuned well :idea:

im new to this style of carb but it has that sputter in park or drive and once it picks up in both park and drive its fine. it only do it when i pull off in drive or tap the gas in park. and both times its below 2200 rpm

You have to be sure if its getting too much fuel r not enough. If its a flat spot u get when u hit the throttle quickly, then it needs more fuel. If its a lazy bogg then u have too much fuel. First thing is check the fuel level. U have a 31 in the primary already ya might need to change the throttle cam. What color cam do u have? Another thing to do is hook up a vac. gauage to manifold vac, stick it under a wiper blade go for a drive. Check yer vac at cruse and go two steps lower on the power valve. If yer cruse vac is 10 install a power valve with the hg of 8.

thanks pontiac455 about telling me about the accelerator pump cam but right now i cant buy the assortment so i googled it and one site said you can flip the cam around to give it a bigger shot so i tried it and what to you know it actually improve drastically but im still going to get the pump cam assortment pack to fine tune it and thanks for all your help
