Did a compression test 2 weeks ago while trying to get truck to start after it ran really rough the night before and wouldn't go at all the next day.

9 to 9.5 bar across all. When cold.

Spark was intermittent and weak looking, so I cleaned the rotor, cap, plugs ect. Still no start, bought a new coil, still no start, voltage to coil was 7.5 vt after resistor, resistor 1.5ohm so I bypassed, voltage 9.5 at coil, still no start. Cracked it, had a coffee, watched some telly, came back out to pack up tools tried it again, started no worries. Seemed to run OK after that but trips where less than 15 min long.

Don't know when carby last serviced, only had the car 4 weeks. Autopro mt gambler were servicing the truck every 5000, not due for service for 3000 more k

Not sure how it could be the carby causing my issues as the problem is identical on gas and petrol.
