Two-stroke lover!
Tonight i got the Puch VZ engine finished. It took a while before i got the right light coils for the ignition. The new crankshaft also gave me some problems, the tapered end for the flywheel was a few millimeters misplaced. So the cooling fins hit the ignition cover, i had to do some annoying grinding.

Yesterday i got some new parts so i could get this engine assembled. The gasket was a little thick, and the crankshaft a little narrower, so it took alot of shims to align it and get the end play right.
More pictures are in the gallery here: https://12v.dk/puch-vz-50-jps/ – on page 2 & 3.
Just to make sure that i don’t get bored, i promised to help “JPS” with his Puch VZ engine. JPS is a very active member of the danish forum billig-scooter.dk.
The engine had knocking noises and leaked oil, so i’m going to change all bearings and seals. The crankshaft is also worn, so it will be changed to a new one.
There isn’t anything other wrong with the engine, all mechanical parts look good as new.
This gallery will contain all the images i take while doing the repair, remember to look for photo comments:
A short video of the noises, it was worse and visible in real life:
