concentric carb problem

Hi guys:

I recently inherited a fully restored 71 Norton from my dad, who passed away. After putting some fresh petrol in the tank and tracing a few things electrically(probably a joke from my dad or his idea of a security system) it lit. After about half throttle, though, I'm getting fuel coming out of the tickler vent on the left carb. I've cleaned the bowl, needle and seat and the banjo fitting and filter assy as I presume this is an indication of a stuck needle. I can't seem to get it.

The other problem I am having is going over a curb at any speed faster than a walking pace the front forks bottom out quite violently.

Any ideas?? Thanks in advance.RR

Make sure that the float chamber gasket is not interfering with the float or the float spindle. Trim the gasket a bit. Change the oil in your forks.

Hi Diego,

going over a curb at any speed faster than a walking pace the front forks bottom out quite violently.

In which direction are you going over them-there curbs ??? :shock:

Curbs

Diego,

Either way over the curb, why are you doing this with a Commando especially "at speed."

Usually I try to go over the curbs on the rear wheel only, then it's no problem! Anyways, I was able to get the bike purring. The problem with the carb, I found, was somebody had cut the bowl gasket and the float spindle? was able to ride up and open the needle... flooding the bowl. All is well and thanks for all your helpful criticism on the curb jumping. I meant going over the small curb off the roadway into a driveway or such. I hate to have to spell it out so clearly for you guys. :lol:
