The only carb monkeying around I do is jets and mixture screws. Be the carb on a bike, a chainsaw, one of my truck engines... if it needs more than that, it's a paperweight and I replace it. I don't even try to synch them myself anymore on our multi-carb toys, ears aren't what they used to be... and neither are cheapy chi-com carb sticks.

Messing with the enrichment valve guts? Um, no thanks.
