Great improvement in the Looks department

Thank you   

The gears as supplied have a 3.2mm bore (for 1/8” motor shafts?) so in needed to open them out to 4mm to suit my bearings and oil seals. They were held in a 14mm ER collet with a second gear at the other end of the collet to keep it balanced and concentric. The hole was bored out to ~3.8 mm using a Proxxon 3mm end mill as a boring tool (I made a holder for these when I made the CD carburettor) and then reamed 4mm. In days gone by I would probably just used a 4mm drill but now I am chasing every micron.  The bosses were then parted off. The finish is not very good but the gears will be skimmed again later in the build.

To test the new purchased pump I needed to build a simple test rig to hold a fuel tank, the pump and a support for the pressure gauge. A chance to drill big holes and not worry about the microns, +/- half a mm will do 

Having the flywheel so far away won't help as any tiny error in the shaft will be magnified the further you get from the bearing. Can you move it closer?

I can't really say for sure why the flywheel is wobbling. However, one possibility would be to drill a larger hole in the flywheel and then fabricate a suitable bushing for the crankshaft thread.
The engine refurbishment turned out well.

Second pedestal completed with its brass bearing and I think I'll move onto the trunnion bearings next ....
