i am going to be swapping my 998cc mini engine for a metro 1275 engine, the engine was in my car before (before i bought it though) so it has the right mounts and everything. i am a little confused because of the starter motor/clutch.

both engines have a verto cluch (small lever out side the casing), the 998 has a pre-engaged starter, but the flywheel on the 1275 has 107 teeth, which is common for a pre-verto....

anyone give me any advice? i would like to keep the pre-engaged starter, but i could fork out and get an old inertia styled one

thanks

Finch,

Normally pre-engaged starters have a chamfer on the flywheel facing forward. The inertia starters have the chamfer on the rear. The chamfer is to help the pinion teeth mesh easily. If the flywheels are not swappable then fit a new ring gear to the flywheel you need but with the chamfer reversed.

hmm is it hard to fit a new ring-gear, or would it be easier to fit a new small gear to the starter?

The pre-engaged starter meshes with the front of the ring gear but the inertia starter meshes from behind - so changing the only starter gear would not be enough.

in my mind (i am daft though), the verto flywheel from my998 should be the same as the flywheel from my 1275 (also a verto), the only diff being the ring-gear. could i not take take the flyweel of the 998 and put on the 1275?
