Water damage, air filter, carburateur, magneto and pont.
Energic motoculteurs when left outside for extreme lengths of time water will enter various parts of the motoculteur. This causes damage to different degrees depending upon the penetration of water.
Initially, water enters through the air filter, causing the surrounding metal element to initially corrode and then disintegrate. The water pools in the filter. See below an extreme example:
This outer element can be replaced, and the inner metal filter possibly saved – No I do not think so!
Very difficult to undo the carburettor from the air filter as it is normally a tight fit but with rust virtually impossible.
The water damage can extend into the carburettor air inlet and cause the following corrosive problems:
This rust can be clean up and out, But it will leave corrosive pitting on the affected surface!
Yes, it can get worse, if water/moisture transfers to the inlet valve/air intake this causes another set of problems.
In fact, if the inlet valve is fully open then you will get moisture into the combustion chamber which will intern transfer to the valve stems and springs and so on.
Look inside the pont/transfer box. Invariably there will be a mixture of oil and water resulting in sludge. And in extreme cases just water, with no visible sign of oil. You must evacuate the water/sludge and clean. Then dry outside on a suitable hot day before replacing with oil in this gearbox.
Here is some sludge I had the misfortune in discovering in an Energic motoculteur C7 B4L, stood for 36 years in the same place – outside.
Another weak spot is the magneto inspection front cup. As you can see from the rust tide mark water got into that level!
Here it is better to dismantle the magneto, clean and replace the contacts. Re-assemble to be sure of effective long term results.
