Trouble starting a Victor

seattle##gs · Dec 10, 2023

Twice now, Victor & a B50, they've been very difficult to start after a fresh top end. After a lot of trying this and that I finally put a socket on the rotor nut, used a large corded 1/2" drill and spun the motor over (no plug) for 5 one-minute intervals. Now it has good compression and started on the second kick. This has happened twice with the big singles. Twins are never a problem. So here's the cure for a Victor or B50 after a top end.

Be sure the cylinder walls are oiled and that you don't flood it. If you flood them the oil is washed away and the unseated rings do not seal. You spinning the engine corrected both and started to seat the rings. B50s are very prone to washed cylinder walls at first and I assume the other BSA singles are as well.

Your mistake was the hill upon which you live is not steep enough!
