Float level

[Charles Frodsham]

That makes sense....as Richard described....one choke per bank for a double choke Solex. Hence on the 3B, a triple choke Solex , I assume it is one choke per cylinder pair, from front to rear.

As you have one “starter” choke hole, then it also makes sense then that one bank exhaust gets sooty relative to the other. Is it normally that noticeable? Maybe other owners could comment, or is your starter choke runnng continuously?

Does anyone here know why only one bank of cylinders would need a 'starter hole'. Certainly when my PAAI 'starter' was partially stuck 'on' there was very bad sooting on all six plugs. I suppose if the hole in the photo could be closed off to prove a point. I have reliably heard that not all of the carbs in the triple Weber DCNL setup have a cold start device, but have yet to have a look at these and understand the reason why. I assumed all cylinders need a suitable cold start mixture. Will probably post a new thread regarding fuel injection, but does anyone know what injection system is available, as mentioned in the spec for uprated Aurelias with Flaminia engines which I have seen published?
