I've tried to breed Commandos, maybe thats why it didn't work ?!

"Causes damage to organs. May cause damage to organs (liver, kidney, lung, brain) through
prolonged or repeated exposure. Suspected of damaging the unborn child."

It is not recommended that you drink (or breath) any hydrocarbon. !!
As a cocktail, thats a doozy - race fuel, paint and fibreglass thinners.

GASOLINE GETS THE SAME WARNINGS....

But doesn't clean carbs as good, must be the mixture of them that dissolves everything...

The warning about keeping away from fire is probably more important, it is extremely flammable.
Cleans carbs well if you spray it down the throat while the engine is running....

To the person that provided the original feedback that AMAL Mk 1 carbys were difficult to keep clean:
Beware using "Clean-R-Carb™ Carburetor Cleaner" and utilise all precautions recommended in the MSDS (link below) for this product, especially be aware of page 10:
"...US. California Proposition 65 WARNING: This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm..."

Grubby carbys may be the preferred option!

How is it that California is the only state in the Union that "knows" a certain chemical causes cancer? Are they that far ahead medically of the rest of the world? As Rohan points out, California says that about pretty much anything that's man-made.
The bumper sticker seen around my parts on a regular basis: "Don't Californicate Idaho!"

Whew! I think someone just pushed one of my buttons. Shutting up now...

Californians know because they care to know. Some rural folk probably still think lead and asbestos aren't that bad either...
 
shit, everything causes cancer, including gasoline.

Just maybe a little common sense could be applied...regardless of state.
 
meanwhile, there is the reality of every toxic soup breath inhaled in big city smogtowns, ....head for the hills, but,

good bet there are scenarios there too altho with way better odds
https://en.wikipedia.org/wiki/Smog
Modern smog, as found for example in Los Angeles, is a type of air pollution derived from vehicular emission from internal combustion engines and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog. In certain other cities, such as Delhi, smog severity is often aggravated by stubble burning in neighboring agricultural areas. The atmospheric pollution levels of Los Angeles, Beijing, Delhi, Mexico City and other cities are increased by inversion that traps pollution close to the ground. It is usually highly toxic to humans and can cause severe sickness, shortened life or death.

Heck, the ingredients of spray on starch add to that too, maybe ironing should be banned ??
along with literally thousands of industrial processes. etc etc etc.
Why have you suddenly gone all old grandmotherly like over having clean carbs ?

Err yes, sorry if there was any slight confusion amongst readees there !!
 
OK, lets take a quick poll here to see who is serious about this breathing toxic stuff.

How many wear a mask while filling up at the gas station. ?
How many others do you see doing this.

Needing Air
 
How much toxic material do you think a paper mask would help with ?

Having said that, the air in some of those parts over there is pretty bad.
In Tokyo 30 years ago, it was quoted that the catalytic convertor in cars breathed out cleaner air than the engine breathed in.

Bottled medical grade oxygen anyone ?

Heck, a Commando could make 4 or 5 times the power on oxygen.
300 brochure bhp ??

I've been out in the 'clean countyside', and the air at night from slow combustion wood stoves was pretty evil.
Almost need a gasmask to sleep at night.
Population outta control ?

P.S. Does Calif EPA allow slow burn wood stoves.
Analysis of the smoke would be a seriously toxic brew ?
But we diverge, it wouldn't clean Amals...
 
Perhaps google has missed that chook flu brought out a lot of masks......
 
further googling shows russia is similar to china with the masks, yanks on the other hand are quite bashful in comparison, at least for now, but,

too much of a thread drift at this point for me, i'm back to needing's norton needing air :D

and covering that, needing's way, from a to z with dyno runs :shock: 8)

including some mild diversions, that are somewhat related

Owen started the thread 'drifting', with talk of Calif regulations on substances commonly found in all sorts of industries.
But happened to be found combined in a very effective carburettor cleaner.
So he can hardly complain... ?

So, back to regular programming.
 
I have come to the conclusion that the stepped spray nozzles in the AMAL Mk1 carbys fitted to the 850's are a nonsense. It seems they were developed to meet a legislative requirement of the 1970's. At best, they were tested on an engine dyno with infield proving trials to meet the above requirements. I suspect they were not exposed to constant road testing by Norton test riders nor was low throttle air:fuel ratio testing possible as oxygen sensors were in their infancy during that era. Their effect is to excessively enrich the mixture during the fully closed to about 8mm throttle slide opening.
I recommend replacing them with the flat top version to reduce the 850's plug fouling concern at around-town throttle openings i.e. less than 3500 rpm.

Can we see the dyno A/F ratio graphs that support this conclusion please ?
Last we heard your readings were all over the shop, and getting richer ?

Dear rohan.
Please keep up. Perhaps go back to page 25 of this thread and actually read the graph specifically regarding richer and leaner. I identified the y-axis and mark the limits to aid your 'we?' interpretation.
As previously mentioned to you, the dyno a:fr is only gives a snapshot of the ongoing dynamic data I observed and utilise for tuning (using oxygen sensor and A:F ratio gauge fitted to my bike). This technology was not available in 1967 or even 1973.
I will be happy to interpret any original data you collect to support retention of stepped spray nozzles. Data-mining this forum for secondary data (search: plugs foul) has 15 summary pages of this concern.
Ta.
 
Keep up - with what ??

Your final words on P25 are these -

needing said:
These are not easy to acqire at short notice but coupled with 105 needle jets and flat top spray nozzles should be the last items needed to bring the A:FR between 12:1 and 13.5:1 throughout the entire throttle range.
Click to expand...

Is "should' supposed to be read as the final word on this,
it seems like the testing hasn't been done yet ???????????

No graph to show the results either ?
Nor a low rpm graph to show the A/F stock stepped spray tube results.

Or are we supposed to guess how this might show on A/F ratios graphed ??
If this is your idea of 'scientific', I wouldn't like to see what mere opinion looks like .....
