Alternative to mixer ring??

[lister]

I found this on ebay, it seems to work on a similar principle to a bike carb, has anybody any experience with it??

The problem I can see is what happens when you run out of gas and you want to switch to petrol, 'cos I can't see where the petrol would go or another carb for that matter. Good idea in principle though.

In the vid its on a car with a throttle body further down.

Basically its mixing the gas and air at the beginning of the inlet system, you would still have carbs further down close to the head.

It looks fab in princable, no restrictive mixers or unstable idling.
I was just wondering if anyone had any first hand experience with it, or new of a reason why it wouldn't work??

so you'd have that on top of the carb ?
if so you'd have to alter the engine lid and the air box
the ring is proven to work and work well on these engines
