Has anyone tried this - Bultaco Pursang, Matador, 2 stroke fuel stabilizer?

Hi,
I stumbled on this on ebay and seems like a dream come true for petrol users!
Has anyone tried and used this - or I am really only dreaming?

I have a 400ml pack of StarTron petrol fuel additive purchased in error. Didn't know there were different diesel and petrol versions.

First offer over £15, including postage, and its yours!

What it has to do with a Pursang, which hasn't been made for many decades, heaven only knows. My guess is that the seller was duped and would like to defray the cost.

Just keywords. If the seller put "Snake Oil" he probably would get fewer buyers. Or not.

When in business as a Classic, Vintage and Veteran motorcycle dealer I used to sell and recomend fuel stabilisers for long term storage of motorcycles-IE over the winter.

Customers who took my advice saved a lot of hassle when they came to use their pride and joy's in the springtime.

The prefered product was the Swiss Motorex fuel stabiliser.

This completely solved the jet blocking problems many encountered before using it, and the fuel still seemed to work OK after five or six months storage.

We also sold and recommended the "Fuel Cat" which just dropped into the fuel tank and was advertised to compensate for the lack of tetra eythyl lead in modern fuel.

We sold hundreds and never had one back-it worked as stated or our customers did not cover enough annual milage for valve seat recession to have been a problem.

Many Scientists told me it was snake oil but our customers were very happy with spending £20.00 instead of a £200-300 cylinder head job.

A Bultaco Pursang is a single cylinder two stroke with large jets in the carburettor-it should not require a fuel stabiliser to stop jet varnishing.

On the other hand the fuel will lose its volatility after a while as the lighter elements evaporate off.

Drain the tank and carb. and all will be well.

Hi,
Thanks for the info. I am going to try it and see how it goes. A small ammount to lose if nothing happens. I didn't realise that Bultaco Pursang was an engine, I thought it was part of the products name!!!!! There is a fuel cat on ebay that I may try as well - http://www.ebay.co.uk/itm/181158211915?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l264
Is this similar to what you sold?

Thats it-changed slightly in shape.

Apparently developed in South Africa during sanctions against aparthied. The fuel they were getting was not much good so an idea from wartime Russian organic chemists was developed further.

In the early days of WW2 we supplied Hurricanes to Russia. The Merlin engines required high octane fuel which the Russians did not have much of.

The fuel catalist developed in Russia was a more sophisticated in-line unit that allowed the Hurricanes to be operational but at reduced power.

Interestingly enough, one of the Russian fighters they built for themselves had a striking resemblance to the Hawker Hurricane

Pursang and Matador were model names of bikes made by Bultaco in the sixties (or seventies?). In my foolish youth I had a Bultaco Sherpa trials bike, which I used to go to school on between trials. I think the Pursang was a 250 motocrosser, and I can't remember what the Matador was.

Enduro version-a Pursang with lights.
