Hey everybody,

I just started my rebuild 2.4t engine for the first time. The engine is all original except for a Piston/Cylinder Set with 9.5:1 compression – quiet a step up from the original 7.5:1.

The idle advance for the original engine is 5° ATDC @ 900rpm. I tried this but I did not like the engine sound so I stopped at this point for now. I’m aware that the more important setting is the 35° BTDC @ 6000rpm but this will have to wait until the engine is run in.

Now I’m wondering if
- My distributor is even safe to use with this compression ratio.
- There is a recommended initial setting you guys can give me.

Also the carbs have not been modified until this point. I was planning to run the engine in with the original settings and to the proper tuning after this point.

- Is it safe to do this or am I risking a lean condition or similar?

Thanks!
