Vintage Alvis Maintenance
Never dilute your spirits too much! - 2015
I was preparing the car for a Concours and everything was clean and lovely so I pressed the starter and although the engine went round, nothing happened.
This seemed like a good opportunity to try my spare magneto - it’s a BTH and has slightly different fittings but nothing that should delay me too much if it happens on a wet winter’s night in a country lane…
Well, after 4 years of sitting idle in the Doctor’s cubby hole behind the seat, it worked!
So I went for a 5 mile drive and it was great as I’d also taken the opportunity to change the 115 jet for a 120. I came back home and took the magneto off as it needed some padding for the mounting strap…and just for the hell of it I put the original magneto back on…
Well, it worked!…so I left well alone and put the car in the garage ready for the Alvis Owners Club South-East Alvis day.
I repeated the previous day’s routine and two hours later + two changes of magnetos + an emptying of the carburettor + exchanging the 120 jet for a 110 jet and I was back home…sort of convincing myself that it was water in the petrol.
So I put four gallons of Esso in it, went off for the AOC meeting, drove about 40 miles and she ran almost perfectly - I still think the 110 jet is slightly too lean
