Default Re: whizzer clutch

I'm having difficulty with all the variables on the clutch adjustment. I have a WC-1 but just did a conversion to the NE-5. It's not quite up and running yet. Before I did this, the bike had little ability to move me except on flat ground with serious pedaling at the start. I suspect that the belts were slipping even then, though I never seriously investigated them.
Now, here are the issues I'm trying to balance.
1. Keeping the large belt tight when the clutch is out (not pulled).
2. Getting the engine oriented so the big plastic belt shield clears the back pulley.
3. Keeping the belt shield from being ribbed by the pedal cranks.
4. Although i don't have a spark plug to install yet (elusive little guys!), I am concerned that the plug its cable/connector will clear the arched lower crossbar. The plug angle looks like a problem. I guess I'll have to see when I have a plug to install.
So far, I've loosened the motor mounts and leveraged the engine to different positions, adjusted the position of the clutch cable bracket, and gotten as much as I can out of the rear wheel position. I keep ending up with a loose back belt or a severe rub on the belt shield...or some of both.
I can relieve the belt shield problem by dropping the clutch cable bracket to put some tension on the back pulley, thereby dropping it 1/4 to 1/2 inch. Essentially keeping the clutch partially pulled. This doesn't seem the ideal solution though. I suspect I'll lose some necessary clutch release potential.
I don't want to go shieldless since I value my inner thigh. I've read Motormike's instructions...but still stimied.


Ideas?
