Hi folks, welcome to a short clip on a cylinder head modification which was required to allow easy starting of my 350 cc single. Initally, I didn‘t expected it to be mandatory, but there was no reliable way to bring her to life without such a valve. As an alternative EX-timing could have been increased or compression reduced. But that does change engine characteristics quite a bit…
Here is the story about the other #twostroke engine modifications which made the valve a ‘must have’: • JAWA 2-stroke power tu...

Je snadné si myslet, že skutečný chlap tento motor o objemu 350 ccm snadno nastartuje. Ale není to tak jednoduché, milí přátelé. NOVÉ startovací zařízení se po několika dnech rozbilo. Jen ventil opět snížil zátěž na rozumnou úroveň.

Good idea. I see decompressor bought from husqvarna. Very good, because they are durable and used in powerful petrol saws. SUB !

Yes, it works. But it is far from being properly sealed. It is gas & pressure tight, but is surprisingly full of oil dirt…

Why not use one that replaces the second spark plug?

@Quiet.Light.Engineering Жыл бұрын

Believe it or not, the second spark plug increases power in a noticeable way.

Can we use 2 oil injectors on cylinder for lubricat cylinder wall like rotary engine ? It possible ?

@Quiet.Light.Engineering 2 жыл бұрын

Well possible. If you find a way to properly meter the oil, hence have the right control mechanism for it.
