Project Vespa Smallframe - First Start DR130 + LeoVince

 After overcoming all the overhaul challenges I had my son help put the engine back into the frame.  We learned a few tricks along the way to help it go better if we have to do it again.  1) Put a short bolt or screwdriver in the opposite side of the pivot bolt to hold things aligned. 2) Put the drop-tail plate back into the lift after the engine is under the frame.

 Other than that the most fiddly part was stringing the cables back in.  I highly recommend fluxing the cables and soldering the tips so they don't splay out causing challenges with reassembly.

 The original main jet was a 74.  We started with a 90 Main Jet based on advice from friends with the same engine + exhaust combination.  The anticipation is that this will be rich and we'll have to move down.  Our close friend has an 85 main jet in his with the same setup as we are running.  We will see where we fall once we get through the break-in phase.

There is a smallframe build database, that I will consult.  http://sfs.alexander-hepp.de/

 And that's about it.  It took half a dozen kicks to get the gas back into the chamber, and now it starts up on the first kick like it always did before.  I'm genuinely pleased so far.
