As no one seems to know how to time the balencer shaft will it be OK to remove it and run without it? Cheers, Geoff

Google knows no balencer. You probably mean balancer.
In German: Ausgleichswelle

You can run the Estrella without balancer shaft. In the simplest way, you just remove the drive gear and leave the shaft installed.

Timing is set based on two markings on drive gears as far as remember.

thanks for your assistance but my crankshaft gear wheel only has one mark as does the balancer gear?
