An old problem, I know, but this one is a bit odd.....( that's the problem, not the writer...!!!). I have built a 1959 A7 from scratch, and have been trying unsuccessfully to get it to fire up. It is a mag model with auto A/R, and I have checked, double checked, and re-checked the timing, so I believe that is OK. B6HS plugs, brand new, and a rebuilt 376 monobloc. Spent weeks trying to get it to go, with some odd results: it will fire up on the left cylinder with the right plug out. It fires on the right cylinder with the left plug out. Each plug gives a healthy spark when earthed on the engine ONE AT A TIME........put them both against earth, and the spark is reduced to a feeble, yellowy-looking thing. I rebuilt the K2F mag, but the only thing I wasn't able to check was the dreaded condenser - does anybody think this might be the cause of my problem ? Has anybody ever come across these symptoms in the past ?
I built my A10 about three or four years ago, and I use it every week with no problems, so this really has got me foxed ( ..or sounds like that, anyway.....). Any help would be most welcome.
I am thinking of buying one of those Brightspark gadgets, which would at least give me peace of mind, depending on replies and advice here, and will of course report back.
