Hi fellows:
The Polski (aircooled) is not running smooth at and above 70km/h. I've noticed that when I change from 2nd to 3rd gear, if I do it faster than usual, the engine does like is running out of gas for a sec, but immediately it recovers. Above 70km/h, the engine is like missing sparks, so it is not running smooth. If I accelerate further, it gets worse and start feeling like jumping. I've been suspecting of air in the gas lines, but yesterday I changed to an electric one. I have to say that now it goes a little better, and since my hoses are new (transparent silicon) I don't see any air on them.
So... I don't know where to start looking:
- Spark plugs
- Anything inside the distributor
- TIming
- Carb
Any suggestions?
All the best!
