Re-fitted the cylinder head after new guides fitted. Connected everything up & checked valve clearences. Started on 3rd kick but only on 1 cylinder. Checked plug - no spark. After examining the wiring I found I had put a negative wire to a positive terminal on the coil on the side that was firing. Corrected this wire. Now both plugs sparking. Kicked for eternity with only backfiring from carbs & exhaust. Then lo & behold it started & ran for approximately 10 -15 seconds beautifully. It then just stopped running & no matter how many times I kick all I get is backfiring with the odd teaseing splutter. I noticed a loose spade in a block (2'' x 3/4'' housed behind the steering head - this has 2 spades coming out of it of which 2 black & white wires connect to) which duly fell off. However, am I right in thinking that this block is part of the old ignition system & is no longer required as it has boyer ignition fitted?
I still think its electrical although the symtoms are similar to fuel starvation. I am flooding the bowls on start up although the plugs seem very dry. I've stripped the carbs & cleaned them but to no avail. Any ideas?
