Another Smallframe fix

One of my buddies, who I had acquired a Smallframe for some time ago, experienced some trouble with the scooter recently. A bit later he took the liberty to drop the scooter off by my house to fix.

Okey, a small test ride revealed a motor willingly starting, but having no momentum when revving up. Nothing had been adjusted; Ignition OK, Carb OK, fuel OK.

My suspicion was either damaged reed valve or carburettor issues. In other words, surgery needed.

 Off with exhaust and rear wheel...

 

 ...revealing the Malossi reed valve...

 

In order to get to the one bolt not showing in the picture, I had to manufacture a shortened hex wrench. But that did the trick.

 

On inspection and breathing through the reed, it felt "different" than the reed I have lying around for the Ferdinand project. The reed blades themselfes were not damaged, so what could it be?

 

Turned out that the screws holding the blades and the metal flaps were loose... and that was all that it was to it.

 

 Torleivs Smallframe will be on the road again after a quick service to a very saggy gearing mechanism. (Wires need to be tightened I believe.)

Lesson learned: Check that the screws on the reed valve are actually fixed before installing.

Yellow fever

Once upon a time early this summer I promised a new Roughnecks member to help him with his yellow smallframe. The scooter had been standing in his basement for quite some time, having problems with staying alive when warm. Typically capacitor problems, so I'd already sourced a new capacitor and spark gap for the scooter. The owner himself had a new coil. 

My "scooter trailer" is very versatile... 

 Ok, surgery...

 Dismantle and exit old capacitor and spark gap...

 Inserting DRT capacitor and new spark gap... 

The coil was also replaced with a new one.

The motor now works, but I am not totally satisfied with full throttle response. I might have to adjust the ignition timing a bit.

 

 Again, 5 scooters in the garage... 

But the yellow fever will soon be gone. 

New toy in workshop

New toy added to workshop this week; a pneumatically driven part cleaner.

That pretty much sums up doing DIY parts restoration up to painting. I am still struggeling to find a decent way to paint top coat of parts. A small spray booth is on my wish list, for now I will have to rely on decent, wind still weather.
