I had to make some of these for my kit. Quite easy, but be carefull and take your time when drilling backelite. If its turning too fast, the bakelite will soon start burning.

Here is a fresh picture of the motor, and I think I have solved the starting problems, I´ve changed the needlevalves to some nos ones, it seems that it has helped. But I´m still considering making some plates to isolate from manifold to carb.

great engine in a great car, I looked at your car at the mai kafer treffen in hannover! I am trying to build a engine like that myself. I am in doubt if I build the inlet manifolds myself or buy them at riechert in germany.

Hi thank you for the nice words!

New features for the motor this winther, is the heads have been redone with new seats/guides and new valves.
The inlet valves is Okrasa valves, so they are 33mm instead of stock 30mm.

Next step is bigger venturis.

Yes ofcourse, both lightned and balanced with the flywheel the clutch pressur eplate and the pulley.
And all the rods and pistons is weighed of to the same weight.

Finally it was time to get the Express motor on the dyno again.
It runs really good now, but the bigger venturies were too much for it, so we went back to the stock ones.
But it seems the new heads are working really well.

thumbs up peter, but i think i have mentioned it, the problem is the cam, heads are fine, valves and rest also but now the original cam is on the end of the possibilities... so next step is an custom grind cam, to get more rpm's and than use the bigger venturis.... Wink but good to hear that the heads are working fine... Wink

Hi Andi I allready have a mr okrasa cam in it.
But I´m real satisfied with how it runs now, it has maximum torque around 3000rpm that is perfect because that is were it goes 100km/h.

The first run on the dyno was 44hp, after cahnging the venturies it was 46hp. And then we gawe it a litttle more timing.
But I´m happy Smile never thought I would get over 50hp with it.
