Flathead Timing

[cubicinches]

I need to know many thousandths from top dead center is 30 degrees advanced on a Briggs flathead. Can anybody help me out with that?

Thank you very much!

I have a spreadsheet that will tell you exactly. If you want I will tell you exactly. Just give me the rod length, center to center, and the stroke, and I'll give you a list from 25 to 35 degrees. Really not a problem. But I need those 2 numbers.

I did a quick check with the numbers I have. They may not be right.
rod stroke
3.3030 2.6772
Piston Degrees of travel
.174 25.0
.188 26.0
.202 27.0
.217 28.0
.232 29.0

.264 31.0
.280 32.0
.297 33.0
.314 34.0

That would be incorrect, Al

Punch through these numbers:


2.437 stroke, 3.875 rod length.

If you’re sure that those are the numbers for a clone, I’ll update my database.

Comments compliments criticisms and questions always welcome.
If the data does not support the theory, get a new theory.

Ummm, NO!

This thread is about the "flathead" by the title "flathead timing", Al. Don't let the old age get to ya -- it happens to us all from time to time.

Thank you Al and Carlson, it does have a stock stroke and rod length. I appreciate the help. If those are the exact numbers, that's even better.
