I bought a 1976 moped. It has a variator, so the engine always revs automatically when going downhill. However, the engine is lubricated by fuel. No gas = no fuel = no lubrication.
Do you have to accelerate downhill because of the lubrication or does it not matter?
I don't know much about the topic yet, which is why I'm asking such a strange question.

Loading...Good morning, I got myself a used Kymco Super8 2-stroke today. We overlooked something. The license plate light is missing the "glass" that makes it shine downwards. Now it shines at the rear of other vehicles! I can't find this part for sale. Perhaps you can help me?
My air filter was saturated with mixed gasoline. Now, on the advice of a friend, I flushed the air filter with brake cleaner. Was that correct? Regards (please don't reply so harshly 🥹)
How many kilometers is the distance?
Do not have to be just mopeds, also normal motorcycles with gear shift I'd be interested to know how long it took you to be able to drive reasonably well and whether you found it easy. LG
There were two other girls there. I insulted the ones who kicked me. They turned around and saw that I was standing and hadn't fallen over and then quickly moved on. I shouted after them again that their mother is known as the Penny Woman of Pleasure because they are so cheap and they just…
Unfortunately I threw the key in my Piaggio Fly 50 4t and accidentally closed it. Now I can't get to it anymore. What can I do to get to it again?

The problem is all 2-strokes. There was a freewheel at the time of the 2-stroke cars, so that the engine turned only with idling and lubricated enough. However, this had no engine braking effect and had to keep in mind that the brakes did not overheat.
With a spoon you can give a gas shot every 20 meters short, or, as I did with the cars, insert the choke a bit far. And don’t let the Töfflis turn excessively high, so brake beforehand, so that the speed does not rotate more than 50% too high.
In order not to overheat the brakes, I recommend that the front and rear brakes be used alternately. So the other brake has time to cool down.
I have been here in Switzerland often in the mountains with my MZ with side cars. It’s going to be a real challenge.
Enjoy your tours

This depends on whether you use mixed benzine or whether the part has an extra tank for the two-stroke oil.
It is better to always give some gas in the mixture.
In severing lubrication (extra oil tank) comes whenever the engine turns oil into the engine. Whether you give gas or not.
But since the oil does not burn, there is a nice smoke cloud if you give gas again.
that doesn’t matter because always some fuel gets into the engine otherwise would go out at any downhill engine
Okay, thanks for the answer.
unfortunately wrong. It is true that in old engines the “standgas” is always supplied – but this is not enough when the engine is turned up externally when it is driven off.
And in the case of more modern engines (with injection), no fuel is actually injected during the thrust operation. It doesn’t matter how they don’t have a mixture lubrication.
