It warmed up enough yesterday. Fitted carbs but still running rich. I have swapped air jets several times, but I'm happy that they are the correct ones.
I tried without air filters. No noticeable difference.
The bike starts with the choke on, but runs without straight away. As the bike warms up, after a few minutes unburned fuel starts coming out of the exhaust. Similar to ticking over with the choke on a vehicle that has warmed up.
I'm wondering if the needle jets are worn. I've fitted new o rings. I think maybe the po had similar problems. I've attached a photo of the piston when I stripped the engine.
I set the timing with a strobe. Full advance was difficult as I had to chase the bike around the garage. It seemed as though full advance was past the mark on the stator. I need to get someone sat on the bike.
I'm thinking maybe condenser or coil. The cost to replace the original ignition components isn't much less than the cost of a Boyer Bransden system.
I think I will be changing to electronic ignition. If that fails I'll rebuild my spare set of 1976 linked carbs, and try them.
Thanks again for all the input, it's really appreciated
