Salut drivers, after some work on other projects, I had again a look at the tomos who is used by my neighbor. It starts perfectly but it doesn't turn high enough. I assume maximum 6000 rpm, then it starts stumbling. Maximum 59 km/h on the meter, maybe 45 real. Carburetor is clean, new Dellorto 15 mm...
Update I fixed the exhaust somehow. The original screws from airsal are trash. Also found that valve for the tank. Some problems with the fuelvalve. Difficult to reassemble. But got it finished. Filled fresh gasoline. One kick...... Running :wink: nice engine. But the seal between cylinder and exhau...
Update - the tank is clean, the motor is installed and has a nice, strong spark.
Only the exhaust pipe has to be installed to be ready for test run. I am very interested how it will start.
To be continued...
Hi shadowranger, finally the nut gave up after plenty of heat with the heat gun.
Could remove the three wheels and replace the sealing. I also saw the famous vraagteken veer. Looks good.
Hi Fons, thx for the link. Describing exactly my problem.
The bad seal on the ignition side is out. But on the other side the M10 screw of the crankshaft cannot be removed. I fixed the piston with the stopper but the screw doesn't move at all.
Thanks fons, I have to order these seals now. I realized that the leaking came from the seal at the bottom of the airsal cylinder. The seal in their package doesn't fit with my block. I have cut now a new seal...
Adios wolfram
Update. Cylinder and head cleaned but the piston looks bad. So I ordered a 38 mm Airsal kit, which I know from my Peugeots to be reliable. The kit is arrived and needs to be finished a bit by dremel. Perhaps I'm going to put another head on the unit if it fits. That's also from Peugeot. To be contin...
Cylinder and piston are removed. One screwbolt has been fixed by welding and instead of M7 it has M6 on the end... :( I hope that I can use a bolt of my Peugeot instead. One of the piston rings is also blocked and needs some ultrasound in a bath of RME. The cylinder head looks as big as a bath tube....
Salut,
I used a screw M6 with the corresponding nut on the other side of the reduction ring.
After heating the manifold with a heatgun from all sides, one clash with the hammer and the incrustation came out.
Now I'm going to inspect the cylinder...
Update: the manifold has been removed after cutting the screws without head with the dremel. Now it comes to remove the reduction ring inside of the manifold...

Thx! The workshop looks a bit funny but they got it done.
Seems to me that the reed valve has the same dimensions like those from my Peugeots.
Ciao wolfram
Update: The motor is out and I wanted to replace the seals. But there are two screws at the manifold that looks weird. How can I take those two things out w/o making damage to the cylinder? Do they need to be drilled out? This manifold is much too small and I want to replace it to inhale a bit more ...
