Solution to the carb blowback problem
This has been doing my head in since i got i built, it would run fine upto around 2500rpm, but anything above that, it would blow all the petrol back out the carb. I tried everything:timing, mixture, exhaust, lifter pre load,coil, condensor, distrubutor.Turns out i got the Cam timing wrong. Picture shows how its supposed to be, I timed it against the wrong dot.

Home made Carb spacer
The carb tends to get very hot because there is no heat spacer between the manifold and carb. You can purhcase proper spacers, but i just made my own. Most companies sell "phonelic" spacers, but i found some nylon in the shed, and machined it following the gasket as a template. This is the prototype spacer,To improve airflow, we radius the two small holes. (That's Dad!).
The outside is then shaped to follow the outline of the carb
