Re: eska 3.5 hp
Well, it's a 1974 model. I know that much. It has a Tecumseh 642-17b engine as a powerhead. The carburetor is a Tillotson.
What was your specific question about it?
Eska parts are available from
www.certifiedpartscorp.com. With the model number, call them at the phone number on their website. They have parts lists and service manuals available for purchase as well.
