The VB is in my opinion a pleasant and very reliable workhorse! As long as your magneto is sound and your carb is not worn out, it will go for ages to come! I once had a 1933 557cc VB, it never let me down. If you are interested I have original (with oil hole on top of the cases!) VB cases in very sound condition with engine number EJ 3141X (1949) I want to swop these (if sound) for 1947 350 OHV cases starting with number BKxxxx to make my 1947 OHV number correct for that year. I also have a timing pinion, a camshaft, two cam folowers, one tappet, a crankshaft with wornout bigend (tapered model the same as all 350’s models, some VG’s etc.), inner timing case, oilpump, new piston rings. All in good useable condition so all in all a complete bottom end. Will visit next Annual.
