54 fordson major timing mark petrol/kero

[christojo]

Hi, Another Question re timing. If I was to use a timing light to time the 54 fordson major petrol/kero as it is running a little bit rough and when it is hot it will not start untill it cools down, do I time it dead on the timing marks or guess 9 degrees before timing mark. Thanks

Time it dead on the timing mark in line with the pointer that is bolted on the dynamo bracket.
