With my RP, which has a (replacement) mechanical pump and a Zenith carburetor, I have found that the float chamber tends to drain if the car is left standing for a day or so. Since I have a ritual for starting from cold which involves checking oil, water and priming the carb, my car starts usually within a couple of revolutions of the engine every time, even if the battery is a bit 'iffy'. Keeping the point and plugs in good condition tends to eliminate ignition problems.
