Hi,
I am in the process of modifying a couple of 29ci Vanguard V twin engines, one is model 290442, type 0361-03. It's a 1991 vintage and rated at 12hp. The other is 294442. type 1171-A1, It's of 1997 vintage and 14hp, I want to get these to rev a little higher than the standard engine, but only up to 5000rpm max to prevent the flywheel from exploding.
I've sorted the inlet valve push rod bending issue by using exhaust pushrods on both valves, but now want to sort out the valve retainers, keepers, and valve springs issues, does anyone know the EC part numbers of the modified parts I require, so that I can order them please?
