FWIW, I found this on the interweb, it may be of interest for Commando owners .
 
"At Italianiron.com, we have been able to confirm the factory's claims of the technical benefits of the SmartCarbs as being a 30% saving in fuel consumption, 6 to 14% improvement in HP, adaptability to altitude and other atmospheric changes, ease of adjustment and 80% less hydrocarbon emissions."

Reads like an old J.C. Whitney add.
"but the big oil companies squashed it..."
:rolleyes:
 
Due in part to the pressurized float bowl, the SmartCarb2's have been proven capable of keeping up with the steady, but variable demands of a 2-stroke engine that is firing on every stroke.

Steady but variable, they really are taking the piss LOL

Consumption, maybe. HP, maybe. Altitude, maybe. Ease of adjustment, maybe. 80% less hydrocarbon emissions - ridiculous! BTW, being generous on the "maybe"s

If it can do that on a two stroke engine and reduce the emissions - it would be a new wonder carb! So, why are not the two stroke engines manufacturers falling over themselves to fit it?
Something stinks here.....
I gave up long ago that standard carbs would work on this engine.
 
Ahh, but we are exepecting to see the new aluminium Amal 930 bodies very soon. No more zinc bodies, these aluminium will be the norm.
 
Amal won't be able to complete, as the new flanged carb manufacturer puts a blower in their carbs. . . . . (According to them)
 
The carbs are made by Tecnology Elevated. It's a flat slide, metering rod (no jets) carb that seems to be essentially an improvement on the Lectron design. The company says it is based on a design by the original designer of the Lectron, but that the two companies are not associated in any way. More info on the carbs at their web site here


Interesting outfit, this italioniron/britiron shop. If you check out their website, you will see that they are also dealers in the US for alloy cylinders, crankcases, Norvil racer front ends, and alloy Norvil fuel tanks, all from TGA/Molnar Precision. We've discussed the alloy cylinders and crankcases on the forum recently, but I don't recall seeing anything about the Norvil sliders or alloy tanks. Pictures and info on the italianiron link above, or on Molnar's site here


Lots of cool stuff now available, but really pricey.

Gardner carbs were not all bad. They were flat slide. I think the adjustment at throttle openings between 1/4 and 3/4 were finer. With Amal carbs you have two sizes of needle jets - too rich and too lean. With the Gardners, , the adjustment was by turning the needle in quarter turn steps, it had a flat on it. The only four stroke I have seen with a Gardner was the Henderson Matchless. I think they were mainly used on two-strokes. But any carb which is good on a two stroke, usually has extremely fine mixture adjustment, or the motor does not really go quick.
The problem might be, that for a four-stroke engine , if you get it running lean enough to get really good performance, you have to keep at the jetting every time the weather changes.

Unless I have read their website wrong, there is only two models from the 1980 year that they list, both two strokes, Commando owners need not apply.
 
$700 a carb :eek: , not an alternative especially as they only list 2 stoke off road bikes in their application list.
 
Some carbs which are used on two-strokes do not like the greater vacuum of a four-stroke motor - the slides might hang-up when open. Some Mikunis are like that.
