Solexes in summer

For a couple weeks now my car has been "gurgling" and jumping around when i put the foot down and i need to feather the accelerator SO lightly just to get it rolling i can barely hill start any more. A while back over at http://forums.toymods.org.au/index.php?t=msg&t h=46332&start=0 Joe suggested advancing the timing a bit... But then tonight it's raining and a lot less hot and the car was pretty much fine. Is it possible that the heat/humidity affects the way the Solexes are running? Is there a "proper" solution besides advancing the timing? I don't wanna get stuck rolling backwards on a hill because the car won't move

bit of a stretch, but my '58 beetle does exactly the same thing, has a solex also.
tune up and timing always helped, but never completely cured it.
cheers,

the temperature plays a big part with the solexs, during the mornings i try and start my car up and it wont idle, i have to have my choke open for a while before i can even start touching the accelerator, because if i try to accelerate it just chokes and wants to die.. after about 5-10mins then i can start playing with the accelerator. my method works though, its enough to get the car running anyway. if you want man, bring it over to my place i can have a look at it for ya?
cheers.

Solex Mikuni sidedrafts have no compensation for differences in temperature. As soon as the temperature changed, they are out of tune, (or more in tune, depending on the initial state). Currently, mine tend to go better with warmer weather, and run lean and fart around if its too cold.
If it gets worse in warm weather, maybe they are running too rich. Tell us your jet sizes and specs, and I maybe able to help.

Thanks for the tips guys. So now i'm sitting here waiting to see if the theory was right, and it hasn't gotten warm again! Sheesh. Joe, might give you a PM once it gets warmer again... As for knowing jet sizes, that's way beyond my knowledge of engines

Sure there's a proper solution; EFI!

True that. Still, i took it in to the mechanic this morning because the last few days of really bad heat/humidity in Brisbane was making it chug along like a Harley with no torque... Turns out 90% of the problem was the old coil. I guess the humidity was making spark go through the air to ground instead of to the plugs. It still has very minor gurgle in the heat, but it's sooooooo much better.

What I'd do is buy a brand new dizzy cap and very good quality leads as it appears (as your mechanic discovered) that the spark may be shorting in the dizzy cap due to moisture or dirt build up.
With extra thick and better quality leads, a better coil or even a booster for the coil you'll soon see that the strong spark will not only a produce a smoother drive but a boost in the power and more money in the pocket from better fuel economy.
The best you can do is re-jet your solexs for your climate or buy an EFI manifold and a cheap computer for similar price.
...just my 2cents.
Good Luck!
