Linkert floats???

45OZ!

At $4.20 a gallon for gas, you might consider your brass boatanchor in another light.

A fellow from another Indian web community carefully logged his mileage for many miles with first his original cork, then a brass float, and then one of mine.
The cork must have been soaked, because his mileage actually increased to 27mpg with the brass, with no other variables involved.
With a float of proper buoyancy, however, he logged an average 35 mpg.

Folks,
These things are just like toilets.
They "cycle", meaning they open up and close down to accomodate the needs of the carb, by restoring the reserve of fuel in the bowl. "Reserve' is why there is a bowl.
Light floats' cycle has a very low amplitude and a high frequency, as the lack of mass makes it sensitive. It is as close to a straight line as possible.
A float that is three or four times as heavy, however, is sluggish, resulting in a high amplitude and reduced frequency, thus extended periods
of time when the carb is fuller (richer) than ideal, and below ideal (leaner).
There goes fuel economy.

Besides controlling the mixture at steady speeds, the reserve is also critical for refilling the Schebler (as used by Linkert) "accellerator sump", which is the void carved into the main nozzle that holds a charge to be expelled upon sudden demand.
Brass floats are inflated in volume in an effort to make them buoyant at all. Plus they must be set significantly deeper to achieve the same fluid level in the bowl, thus taking another huge bite out of the reserve space.
Some of you may remember that some flat-trackers actually added volume to their bowls: http://www.beautyofspeed.com/gallery...ert-bowl01.htm
(My ultralight DURABLEs are smaller than original floats, in order to achieve the same buoyancy and setting with less density.)

The bottom line is still that brass floats don't float.

Cotten, Cotten, He's the man. If he can't do it, no one can!!!

I used the Armstrong floats for many years without a problem. My first long term experience with one of Tom's floats was in a M35TP Linkert on my 46FL. While I was breaking the motor in I was consistantly getting 50mpg. I had never been able to break the 40mpg barrior before. After it was wore in and was subject to regular hard use it dropped to 45mpg. I'm a believer in the Durables. Even a 2 or 3mpg improvement is significant if you ride your motorcycle often. But even the Durable didn't help when I was dragging the sidetruck on the Cannonball, I only averaged around 30, despite leaning it out till it rattled a couple of times.

Cotten, Do you have a web site or how do I go about getting info and prices on your floats? Sorry I'm not in this loop of knowledge. If several were purchased for spares, what is the average shelf life? Thanks, Bob AMCA #6738

Bob!

I have no website.
I cannot even browse this forum any longer on my WIN98 computers, and must borrow my wife's.

The shelf life of any float is infinite!
Its when it is in modern fuel that the clock starts ticking.

(Ironically, modern fuels stay stable as well in glass; But in the presence of floats and other test materials, the fuel goes rancid! Not only does fuel ruin many floats, floats ruin fuels, over extended exposure.)

I cut the newest and most resistant material on the planet, and when it is improved, I shall be replacing any older productions that fail with the updated material.

(My competitors seem to do fine with obsolete formulations, except for in the Pacific Northwest last season. Who knows what shall come out of the pumps this season? We are not in a gas crunch yet, are we?)

Please post me direct at liberty@npoint.net for pricing and ordering instructions, as I spam at this forum enough as it is.

Thanks for your interest,
