A bit on the side.

Here's an interesting one.

This is prompted by the carb placement thread, but I don't want to tread on anyone's toes with my meanderings.

What's to stop you, in principle, having the slide and needle laying horizontal. Sideways? With a seperate float chamber.

Wear on the needle? Or does the needle get pulled forwards anyway?

Just a thought.

Probably before your time but Amal did produce carbs with horizontal mixing chambers (but of course these had separate float chambers).

This is the only online reference I can find after a quick google: http://members.home.nl/roelofengrietje/specs.htm

Every glow motor I have seen uses a horizontal needle and throttle barrel and a lot of big ww2 aero engines used a horizontal barrel throttle, didnt have  a needle though, cant see anything wrong with fitting one laying on its side except there would be higher wear on the underside of the componants

A friend had a Yamaha 550 Virago with twin carbs with horizontal slides.

I've some experience with remote-float carbs, which were once used on racing bikes. Stupid idea. If the float bowl was aft of the slide (as it was on the bike I fettled), it ran lean on acceleration and rich on overrun, so was never right. It took a bit of engineering to get the float where it belonged. And even then it was off to the side so the thing had to be ridden with the imbalance in mind.

But if it's a solo off to the side shouldn't have any real effect. Different with an outfit of course.
