Our Seagull would only run going downwind. Once we turned up wind to get back to the boat it would die and not restart until we turned downwind again. Limited our exploring with the dinghy as we learned only to start off upwind which didn't get us far before the damned thing would quit. Didn't test it to see if it was bullet proof because I didn't have a gun to use it for target practice. Suggest if you have a Seagull you take a gun with you as they would make a great target 'cause they aren't good for anything else. Found it's unreliable nature was great for fitness, though. Rowing our Redcrest around French Polynesia kept me in great shape. If you want one with little hours but probably a little crusty after all this time ours is at the bottom of Opunohu Bay, Moorea, FP. It conked out once too often and I put myself out of its misery.
Lucas fuel pumps only take a little bump with a hammer to get them to spring to life. That's the reason they put a crank in the MGA's. The crank reached up nicely under the rear fender to oh so gently tap the fuel pump. One good thing about Lucas electrics is you could take them apart and often fix them. Can't even try that with the most other electrics. Actually had very little trouble with the Lucas electrics in my misguided love of Brit. Cars over many years. Started off with a 1960 MGA, then 1960 AH 3000 two seater, 1967 MGB, 1966 Series Landrover 109, 1970 Series Landrover 88 and 1988 Range Rover.
