Thanks Simon, your blog is a goldmine of information, and not just for square fours.

So for future reference, I am advised that a 120 main jet and a number 3 slide are the way to go for a 626 concentric fitted to a mark 1.
I will persevere with fixing the Solex, but it’s nice to have it running well. Just need a bit of dry weather.

Thanks Paul. It's fun writing those posts, but it's got a bit of a Honda bias at the moment!

Hi Guys; - wrt the concentric sticking due to suction: - take the spring out then streach it to approx 1 & 1/2 to 2 times the unsprung state, then simply refit... works fine for me! Cheers.
