Have a 40PA10 Solex on my 67 SIIA and I have a question for the group. when the truck sits for a while (sometimes up to 4-5 weeks) without being started, I have difficulty starting the truck. I have noted that upon removal of the carb top, the float bowl is dry as a bone. I will fill it with fuel, refit the top, start the truck and off we go. then it sits for a few weeks, and it is rinse and repeat this process. My first thought is that the fuel is evaporating from the bowl, since the truck is covered while not being used, and maybe getting hot, but wondered if there is something in the bowl allowing the fuel to drain out, although I can see nothing that would cause that to happen. Any suggestions would be helpful so I can begin to chase this rabbit and repair it. thanks

check for plugs in the bowl usually lead may nee to take carb apart
Gm carbs where bad at leaking. I use JB weld fast setting on the plugs
clean the area with emery cloth and put a coating of epoxy over them

I find the best info for Series trucks is at www.gunsandrovers.com. Series are about all you find there. My 67 is similar, but I just pump the gas a good bit. Swapping the fuel pump helped a good bit with this for me.
