LT-1 Replacement Carb Suggestion

[GaryH]

Eric, I just got done pulling the carb. I took out the 8.5's and installed a 6.5 in the front and a 7.5 in back. That's the only ones I had laying around. I studied the floats and they look great. The hangers are square and do not appear to have ever been bent for any reason. I reassembled and reset the floats. Something is definitely amiss there. I have to crank the needle down almost to the point that it's flush with the top of the carb in order to set it correctly. That's both front and rear. I took it out for a ride and it's better. It likes the 6.5 in the front. I have better response and it pulls better at light to medium throttle. For the first time since I've had the car it had a consistent idle every time I came to a stop. Skies were threatening so I didn't go far but it is improved. I'll pick up a set of needle and seats tomorrow and see if they are any different. If not, I'll take it back apart and replace the floats and adjust as you suggested. With your help maybe I can get this squared away Thanks for taking some time out on this Easter Sunday and helping!

Gary;

I'd still replace the needles & seats as well as the floats just to eliminate them as a possible cause. If you can't find them locally for a decent price, let me know.

Glad to help.

The project is complete Eric. I installed the floats and needle & seats this morning. I took it out for a quick ride and it seems fine. I will know better after I can put some miles on it on a warm day. I don't know what the deal was with the floats. They were the same weight as the new ones and had the same hinge angle but now my needle & seat height is correct. Looking at it before I took it apart, the float drop had to be way off. They were both screwed down to almost the bottom of the bowl.

Gary;

I had a hunch that would clear it up. Guess we'll find out for certain once it warms up and you can take it out and hammer on it a bit.

Keep me posted.
