Long time no see, Dave!
Does ASBO 19's engine still run on points ignition?
Assuming it is carb and not ignition-related this might not help, but I do have a very low-mileage Pazon Sure Fire kit (Better than the Boyer, it only came off ASBO 12 because I fitted the magneto, it worked very well), this is up for grabs if you are interested.
I also have the Dell'Orto PHF32 off my old Electra-X (worked fine, it was replaced by a bigger Mikuni!), if the TM32 really won't play ball.
Drop me a message if you're interested, I assume you're still local. Both items will be **cheap** if they're staying in the family.
