After only replacing the diaphragms of the su carburators the engine started.
Due to some accident damage which had been repaired badly, the Healey has some structural problems on the front end. I need to replace the front part of both chassis rails. Both upper engine bearer struts are damaged and also need to be replaced. I found another Healey chassis which can be used as donor. It’s not a BJ8 but BJ7 chassis. Luckily there isn’t much difference between the BJ8 and BJ7 front end of the chassis.
