tuning secondarys

Here is my question i recently installed a pony carb i had gotten from blue_zuk installition was a breeze after pulling the stocker. i have tuned the carb so idles great had it idling almost 400rpm, 825 is real smooth hardly know thing is running, after soon test drives it bogs when you stop the gas off idle(it does both when reving and mashing gas on the road) so i took it for run oh the freeway, it seems to lack power under wot(wide open thottle) has less power than the stocker, also it seems to be running lean under a load, also its running hot on the freeway at WOT(another sign of the carb running lean) i was wondering if there is way to either rejet the secondary or least une it i am familar with 4barrels. i had read several posts claiming the carb just needs cleaned or rebuilt. i was just curious if i was overlooking something simple been toying with adding a factory vacuum restriction (those little pastic thing on vacuum hoses that slows the secondary opening for emmisions) to see if it helps.any idea would be greatly appriated.

Re: tuning secondarys

I don't even have my secondary working. I used a tie strap and strapped it so that it won't open. The only time I notice a power loss is when I'm offroad trying to go up steep hills or bogging through a mud hole.

Re: tuning secondarys

about the best thing to do now is take the carb off and take it apart for a good cleaning. while it is off we can use a dremel and "match" the ports better. when we reinstall it, use a very small dab of grease to make sure there is not vac leaks at the carb base.

if this doesn't help it, i guess the rebuild kit will need to be used. any other suggestions????
