[QUOTE="pplblazerdude, post: 679105, member: 5305"] Currently on my buggy I have a impco 425 with a adaptor to quadrajet baseplate on top of a adaptor to square bore. This is the way it was when I got it. I have had trouble with off idle power and have found that I have a vacuum leak around the throttle shaft and can't seem to get all the carb gaskets to seal good. Has total of 4 with all the adaptors. I am wanting to switch to a Holley throttle plate to eliminate all the extra crap. What throttle plate are your guys running? Did you have to do any mods to it to make it work with propane? I have been looking at this one http://www.jegs.com/i/Holley/510/112-118/10002/-1 Only thing I have seen people possibly do is plug the small hole in the center of the ports. Please let me know your thoughts as I'm sick of this mess. Sent from my iPhone using Tapatalk [/QUOTE]
