Refitting the timing chain...

[unfazed]

Anyone know of a possible timing mod
Reason being I decided to balance my carbs, thought it best to check valve clearance first
They were spot on.

When I turned the engine for #1 tdc noticed my exhaust cam was not aligned with the cam mark but was in the
One o'clock position
My engine sounds right runs good and valve clearances correct so decided not to worry about it
But it's bugging me so the only conclusion I can think of is that the previous owner had intentionally set it like this as a power mod ?

No power mod, it is a tooth out.
I have seen it before where the owner thought it was close enough, he did not realise it was a tooth out. Engine were running fine before and when we fixed it he did not notice any difference.

Before I changed my cam chain it was over a tooth out because the chain had stretched so much, it was running fine except for the rattle and to be honest I did not notice any difference either.
