The 112: regular orange, black & White,
the silverstar black & Grey and black yellow Red for the Belgium market.
The 116 is a Small amount in Gold color limited edition.
I have a few 153.
They are well build.
Ignition can be a problem on these saws. Easy to fix.
Always control the crank threads on flywheel side.
Is the flywheel removed before with a incorrect puller, the crank threads could het damaged.
Those shims keeps the needle bearing in center.
It depends on the width of the Small end from the conrod.
In those ipl you wil find different partnr for the crank.
Look for a makita dpc7000/7001, 9500/9501 or for a dolmar 309/343 concrete saw carcase and swap the ignition parts. I have spare coils and flywheel over here in Europe.
