125 for cylinder timing question?

[gat2013]

I have a 125 but have 0435 anglevalve cylinders on it. My question is the timing going to be the same or should I have it set at something else. A guy told me to set it at 25 degrees or is that what it should be at with the 125 cylinders on it. Any help would be great.

I think most all Lycoming were at 25.
The 0360 book I has says that some models noted were to be set at 20.

The 200 we have is one of those noted.

Perhaps they wanted it set at 20 for the higher compression engines.
