I have a 65 herald and I’m in the process of fitting the third 1.5 engine first two were midget engines and both had bottom end problems, so I found a low mileage 1.5 dolomite engine ,I fitted it without any problems , now when I tried to start it the starter motor wouldn’t properly engage the flywheel, me thinking it was the starter motor gone bad I got another one only to have the same problem at first it just hit the flywheel like the teeth were not lining up so I added 10 millimetres to the spacer which got it engaging but wouldn’t not turn the engine over quick enough to start it , I shipped the car off to a mechanic mate of mine and he is baffled but he does think the flywheel (which came with the engine is the wrong one so won’t match up to the starter motor,the gearbox is from a spitfire non overdrive any ideas will be appreciated as I’m totally baffled cheers
