Hi Speedy, Tyler,

is that Victa base 18"? It looks it in the picture. I would try and swap bosses if it looks to be viable. Disc with swing blades are better and it will be original spec again.

I don't know how you fiddle with those springs. I had a lot of trouble attempting to swap a governor spring on my B&S last time. They are fiddly to remove.

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