Yes I've probably already spent more than the mower is worth with the carburettor and magneto. (roughly $175 AUD)

I had an idea Briggs and Stratton were quality engines but it's not what I'm hearing from a lot of repairers.

Some unkindly refer to them as Breakem and Scrapem

Anyway the "free' market is drying up as the costs of parts (particularly the freight) makes for some expensive "gems"
