I had a McCulloch 484 and it was made in Italy by another company. The 610 wouldn't happen to be the same deal would it?

The cheapest Ryoby bent shaft whipper snappers sold in the late 1980s were as consumer grade as they come and even they had a clutch as standard! They had the torquey, relatively low revving 31cc reed valve motor made by U.S company Ryan with your usual Walbro or Tillotson carby. I still have one that I use today as so many were sold in their heyday that you can't give them away now.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
