Carb tuning - Starting

[redefined]

Ok guys so this is my first carb motor I've owned other than my karts that I race, heh!

So there are a few things that I've noticed and maybe it's in the carb tuning, wrong carb for the motor, or something unrelated to the carb all together. Any input into the following things would be appreciated.

1. Cold starts. In the summer, 2 pumps of the gas it it seems to fire up just fine. When it's cold outside or sometimes in the summer weather it takes 5-10 and it takes a while to crank over.

2. Hot starts. Drive the car for 20min, say to Subway to get some lunch. Now just run in to grab a sub and when you come out it's not really wanting to crank. Or it will, but you just gotta crank it a few times and give it a little gas.

3. The smell. This is also my first classic car, it's a 68 Camaro. Now this might not have anything to do with the carb, maybe it's just the exhaust but a 5min drive and anywhere you walk into they'll be able to smell the fumes.

Are these all normal things that you just have to deal with in a carb motor? A couple of these reasons are making me really want to do an LS swap and go fuel injected haha

The car is going to be used for weekend/nice weather, track days/time trials, and autocross. The wife loves it too and would like for us to take it out more but we don't always want to smell like exhaust at dinner! haha

Thanks in advance!
