No clue about working on carbs

thanks a lot. that makes sense. the guy who helped me put it on told me i wouldnt need that because the carb i put on already had something to do that????? i dunno.. but id have to buy a new one because that one was broke. which if thats the problem then thats why my single bbl probaly didnt work. will the choke thermo work the same way with the new carb b/c it was set up different from the single bbl. i had to change the position of the throttle cable. i will go look in the morning to see if the old choke thermo will at least match up. just to clear things up, is the choke plate the flap thats near the top of the carb?? remember I= carb retarded. thanks for the simple explaination 65val....this is kinda my learning project so dont feel bad if u have to break it down like i was in kindergarden b/c i probaly need it that simple.
