My Scooter is not running correctly.

More and more each day we are spending a good deal of time on the phone with people who are reporting running issues with their Lambretta (or Vespa).

In most cases when we quiz and probe, a comon theme is not using your Lambretta often enough to keep the fuel fresh and new. With more and more ethonal being addded to modern fuels this is causing us two strokers more issues.

IF you are experiencing poor starting, poor running and over heating issues, and you fuel is one to two months older, considering flushing your fuel system and putting fresh fuel in. If it is even older then this, chances are you need to clean your carb out as well.

Adding a good quality fuel treatment is at present becoming a necassity for us, especially as we dont tend to use our pride and joys every day. The more casual rider popping down to the club meeting once a week or month, may not cover many miles and thus fill up a lot less. Adding this fuel treatment will help no end to prolonging the life of your fuel, engine as well as you suffering less running problems.

If you want a more indepth look into the issues of modern fuel, read on..........

Three major facts on why Ethonal affects us:-

1) Ethonal attracts water : This has many issues for us, because ethonal is a hydroscopic, it will absorb water into our petrol tanks, carbs etc. Thus the older your fuel the more of an issue this is. Back firing, running high, poor starting, over heating can be cauased, and when we look further afield, rusting of the petrol tank internally will not be helped with the presance of water.

2) Ethonal has a different octane rating : This can give a few differing issues, but if you have a higher compression head, your timing is too advanced, or you run higher tuned engines it will affect you more. If your engine is set up to compensate for these issues, and the fuel does go off and your octane rating drops, then again the same running issues we have mentioned before can occur. On the other side of the coin, if your engine has not been built with the higher octane ratings in consideration, you might find over heating (usually shown by blowing a hole in the piston, blowing a gasket, things coming looes throug extra heat expansion, can affect you and your scooter.

3) Ethonal is a solvent: Being a solvent can have many affects. We need oil in our two stroke enggines for lubrication, oils protects our moving parts. Ethonal can flush and wash this out, while most modern oil manufactures have compensated for this, some older or lower quality oils offer less resistance. Oil seals, gaskets, seals, and rubber can all be affected by ethonal. Again most modern materials have been manufactured with this in mind, but some parts can be affected.

As Ethanol is a solvent, it can breakdown sludge and deposits in the fuel system, releasing them to flow throughout the engine, but a bigger effect is inside the carburettor. Our carbs have very small holes in jets that become clogged and harm engine performance.
