Baffled!

recently rebuilt engine, it ran fine for 30 miles then died, ran briefly, then died again. I stripped the carb and it ran ok for a couple of miles then died again. Another (serious!) carb strip, this time it will only tick over, now it fires when kicked over but will not run.
Today i changed the coil, ht lead, cap and plug, no change, I turned the engine over with a drill, only very slight arcing around the points, no sign of leaking oilseals, comression fine, spark seems fine. Timing is a worry as i set it at 19btdc but to get it the stator is fully rotated anti-clockwise, apart from that im at a loss as to what to try next
Any ideas????
ps its a sr175 barrel, 18mm ma18bs5 carb and standard series 2 exhaust
