have an 8 hp Tecumseh engine on my 1986 ariens 924 and need to know what I need to install to mount a light on the unit? I thought I read in the book that an alternator needs to be added under the flywheel. how expensive and big of a job is it to add and what parts do I need? after all these yrs I finally think I need a light! thanks mike.

   For the alternator part you can get a view of what the alternator looks like and how it mounts from the link below.   The engine is to a HMSK80 from around the mid/late 80’s.   The alternator has a wire about a foot long that runs behind the flywheel and cowling.  It’s got a connector on the end that would plug into the wire connector from the light.

>>how expensive

   The alternator above is $55 new.  A new light would be pricey also.  Used parts off Craigslist would be much cheaper. 

>> and big of a job is it

   Not so difficult.  Remove cowling, flywheel, install the alternator, mount the light which would involve some minor fudging, if needed install matching connectors on the alternator and light wires.

>>parts do I need?

   Not sure if all HMSK’s have the mounting holes for the alternator or if all flywheels have room for the alternators but they probably do.

The flywheel for the alternator is different from a standard flywheel. It has magnets built in to it. There are several different versions. You need to get the one that is designed for your engine.
