How can i find if my engine has advance timing on it, the reason is both companies i emailed came back with option to get newer ignition system with advance timing capability.....

Looks like cost or shipping n repairs will come very close to cost of getting newer type ignition system, if i can find if my engine is capable of hooking up to advance timing system then i'll get that instead.

But pulling out engine from this plane is big job n i don't know how it's mounted in as there are screws going in from sides of the fuselage also, so pls don't ask me to do this....
