mine has got to be one of the worst. if i dont start it for two or three days, it doesnt want to start the first few times. if it is under 70*F or over 80% humidity it doesnt want to start. i have a carb rebuild kit on the way, have replaced fuel filter, plugs, cleaned up distributer, it has good everything else, it just doesnt want to start. i give it plenty of gas. any recommendations? is anybody else's like this?

What carb?

Sounds like the fuel is evaporating from the carb, or leaking out the bottom.
Mine does that, so I JB welded the well plugs on my Q-jet. I forget if it kept doing it. I just made sure to start it up more often.

The humidity and temperature thing is another matter. The choke probably isn't working right. What type of choke is that carb outfitted with?

yea, im sure it will get better after i rebuild the carb, but thanks for some ideas. im sure the carb is leaking or something because it had about 13 psi of fuel pressure running through it for who knows how long. more ideas are welcome.
