Hey kjtosco,
Great to see you're enjoy the 'experience', I'm only 2 months into ownership and loving working on the little car.
I also have this issue where after a hot journey the carb would kind of wee over the engine from the spout sticking out of the plastic housing at the bottom.
I have in the interim run a small tube (not air tight as to create resistance or a siphon) from this spout, down the air intake to exit just behind the rear wheel so at least it relieves itself on the road after a journey!.
I'll try and get a pic tonight if it helps.
Ozza
