You might not believe it but I put timing marks on the balance shaft drive gears and a key for each bob weight. Because I did assemble the assembly wrong one night, and did it shake. Hence I stupid proofed it
No, I'm sure it's an ignition problem probably haven't stupid proofed that yet. Twisted crank is a consequence not a cause I think.
But yes the press fit was a bit light also.
Ok, more searching, seems the problem is self inflicted, one of the push fit plugs from one of the ignition triggers was only just (or not, depending on how the engine moved) in. Now it's fixed the engine runs much better, still rattles around a bit but not harsh. I need to stupid proof all the electrical plugs. Yay.
Fly you bastard! And it did.

I'd love to say it was me flying it but no, my test pilot.
He won't let me fly it yet, airspeed indicator is not working so a new one is on order. Old one was a freebie from a crashed gyro. Thursday might be the day!
Did he say if the power to weight ratio was a big improvement?
Strokers Galore!
He loved the power!
Congrats!
And the lawn looks to be nicely mowed as well.
Good work Fletto..

Neil, what shrinkage factor do you work to for your general LM25 equivalent patterns ?
I'd better make up patterns for the Lyster calipers while I have some here...
About 1% / 1.5%
My old alloy shrinkage ruler was about 4mm in 300.
I must say it was a dangerous ruler to have just lying around the workshop.
