Mornin' everyone!

I have about 1500 miles on a new engine (ZZ4) when I am driving and the engine is warm if I stomp on it there is a delay (maybe like 1-1.5 seconds) before she busts out and flies. Is this normal or do I have issues with my carb. After the delay she will roar to life and fly!

Bare in mind that I am basically dumb about mechanics and if I'm not using the correct terminology I apologize.

I was thinking it could either be the throttle cable or problems with the secondaries on the carb. Maybe this is normal though...someone help me out!

Thanks a ton guys!

It is because it is so cold here in Central Fl lately. :lol: :lol:
It is probably just in need of a fuel/air mixture tweek. Check your timing also. I am sure it is something simple. Mine was doing the same a couple weeks ago I leaned it out a little and it is running great. After I warm it up. Don't we live in Florida???

Sounds like the accelerator pump and shooter is not setup properly for your engine. What carb?

76RED - It was chilly this morning! Supposed to be in the 30's this weekend from what I heard...COLD. Hopefully none of the guys from the Great White North read that! :lol: Hey, maybe my blood has thinned out after 20 years in FL.

I have an Edelbrock/Carter. I have no idea what fuel pump I have and no idea what the "Shooter" is! I swear all you guys make me feel so dumb! :yesnod: I need to learn more about my car!

Dan those Edelbrocks are pretty easy carbs. It has been awhile since I have played with one. I will let the guy's that like them chime in. I had one I could not do much with it probably needed rebuilt. I ended up with a Holley.

I have been like that since my first winter here. I thought you could swim all year here. :confused: :confused: I need to replace my heater core and that is not just for the defrosters like I keep telling everyone. :lol: :lol:

I had the same problem with my car. 76 L-48.
I took it in and had a friend of mine rebuild the q-jet (while Lars lent me another).
The car has run better ever since.
I would look at the carb.
Good Luck!

I heard it. Chilly ? It was -5 yesterday morning - all the way up to +3 this
morning. A few more degrees and I'll be ready to open the pool for the season.


BTW - what intake manifold are you running. A high revving single plane intake
will cause symptoms like you describe. Also - I agree - look at accelerator
pump operation and timing to help adjust it.
:seeya

Ooops! Sorry to complain about 30 somethng degrees, that's the low by the way. The high will probably be around 50-60 degrees.

I'm running the stock ZZ4 intake (don't know exactly what that is). I don't even know how to adjust the mixture so I'm reluctant to mess with it oo much. Another guy I work with agreed with you guys and suggested looking at the accelerator pump. Maybe I'll take it to someone to have that checked out. I hate to think I'll need a new carb...~$300 buck sure would look better in my console where the stereo is supposed to go! :lol:

Thanks for all the info...NHVette: STAY WARM! My sister lives in Goffstown and I know she's cold!

Haha - my brother-in-law lives in Cocoa Beach (USAF geologist).
Don't worry about me - I'll be the one out in the yard getting firewood -
at 6AM - wearing just shorts (or maybe less) :p:
