Evie: Valve Lapping

 First time lapping valves and was surprisingly straight forward.

The suction cup was fine on the larger intake valve, but would never successfully stick to the smaller exhaust valve.  But just by keeping downward pressure on the valve while spinning, was able to get the lapping done.

Thought this was going to be the magic fix, but after getting the head back together, the psi hadn't budged at all and was still down at just 35.

 

 

Evie: Ain't Got No Compression

 Not getting anywhere on 30 psi.

 

Evie: No Compression

Stole the points with the nice new white wire from the model engine.

Also got a new roller from eBay to replace the very worn one.  Got that installed along with the new points plate.  Added 650mL of new oil, got the aux gas bottle and battery hooked up and everything was going swimmingly but then...

No compression at all.  Absolutely nothing.  Feels very much like it did when Ivy had the valve stuck open.

Really should have caught this sooner when I first installed the kick pedal... but oh well.

Suppose it could be something with the rings themselves but given that the Early Head is entirely untested, kinda thinking I may as well do that leak test.

 

 

 

Astrid: The Final Stretch

Some odd jobs, but this pretty much gets us to the final point.  The only thing left to do is rig up the killswitch and secure the wiring, and also decide how to hang the gas bottle.  From there, it's just kick and cross your fingers.


Carb gets mounted and air hose attached (which was a pain to fit).

700 mL of the Castrol 20W50.

Something odd - if you attach the kickstart lever flush to the case, it won't clear the exhaust on the way down.  I'm not sure what's out of whack.  Maybe it's the wrong model of kickstarter, or maybe it's the wrong exhaust.  But either way, I had to mount the lever out at the very edge in order to get a full rotation.  I think for the short term it will have to do.

And the big moment - 120 lbs on the compression test!
