The twin build

Looking forward to your ideas on the oiling problem, there's been quite a bit of chat on the forum on that topic.

Actually I found the twin much easier to time than the single. I used the #2 piston with the WOK timing method and found that provided easy access to the insert the gear wheels, primarily because number one was at the bottom of the stroke and out of the way.

Good work Butch! First start can always be a challenge, all the little unknowns come into play. We startup and test a lot of engines here and sometimes they just don't want to come to life. Patience and a methodical approach generally win out unless there is an error of some sort with the assembly.

What a beauty, and a lovely smooth runner.  Thanks for sharing your work! The issue of intake and exhaust manifolds alignment on the twin was very interesting to me...I can see now why that is a critical issue.

I was also interested to note the movement at the raised oil pressure gauge- showing very slightest rocking of crankshaft end to end- though invisible elsewhere.  That would inevitable due to the long crank and separation between cylinders, right? The lack of any other visible movement was very, very impressive. The value of your flywheel matching/adjustment method is well proven again.

Where's that link/thread to set valves by timing, vs lash ?  I've got enough hours, I need to adjust valves and would like to try the timing, maybe clean up the fluffy carbon that blows through my exhaust.
