I posted before about my Eska. I thought it was a 3.5 hp but I thoght I should check the numbers and it turns out the emblem on the front of the tank say 3.0 hp. I then read the metal tag and it reads 1973-A 57-000275. I cannot find anything online that matches these numbers. What year is my motor and what fuel mix is it. I probably need to rebuild the carburator but what info do I need when I order parts? Thanks
