Subject: Re: 2L engine problem
Oakley, can you please keep us notified how you get on? I have the same symptoms with my 2L, though it has just a single SU in the normal place. The cams I've inherited have the flat-topped profile you describe and are timed symmetrically with about 40 degrees of overlap which seems OTT to me though it is, I understand, a recommended change to the very conservative Lagonda setup.
