thanks Alan i know it sounds a daft question , it all started when i was seaching ebay for a hif38 carb and out of the blue up pops a midget eng in really good nick it was a 1500 and was complete with twin carbs ,the lot, with 2mins 30 sec to go it just got me thinking , shall i,sharnt i,in the end i dident but i thought i would ask as it seems everything is the same except there is a sump instead of a gearbox . i also thought that since hearld and spitfires were all bmc they were the same, cheers anyway wal
