I've got an 85 Z28 305 w/ teh stock 4bbl rochester quardajet carb. Lately, my carb has been hestitating very bad when I push in the gas from a dead stop or anytime I have low RPM's. It only does it when the car is hot. When I start it in the morning, the choke keeps the carb running fine. My mechanic told me I probably need to overhaul the carb. I've never rebuilt a carb before, but I'm willing to try. Do you think I should do it? and, do you have any tips?

 

I rebuilt my carb on my 84 camaro about a year and 1/2 ago and right after i did it ran real crisp and nice. They say you should rebuild your carb, putting new gaskets in and such, every 3 years. Heard that somewhere.

But it's like this.... you should put in to your car what you want to get out. It's really not hard, more like a little puzzle than anything. It takes TIME, you MUST MUST MUST keep track of all the little parts bc if you don't it won't work or will run very poorly, and you need to make sure if you are going to clean it, clean it well bc you don't want to have gone through all that hassle and then have it run exactly the same as before. It's a good process if you've never done it before as far as a learning experience. Thing is it's going to run better but not new simply bc it isn't new. The bad thing with carbs is as soon as you rebuild it and make it all nice and shiney and clean, the first thing that happens when you start it up and begin driving it again, it starts the process ALL OVER haha. Kinda frustrating but ya gotta deal with it.

Back to your original question though, yeah it probably just needs a good cleaning and it'll solve your hesitation problem right up. When you're done and you got it all back together make sure and lube up all the moving parts real good too. Should be real nice and crispy afterwards. Hope this helps and motivates you some. Good luck. :lala:
