Yeah you need to stay away from mower shops unless you know you can trust them Byomarimba , a lot are scammers ,I went to a shop close to me and he tried to sell me an old Victa 18 that he said only 3 were ever made and said Victa had offered him $3000. for it as it was a very rare model but I could have it for $2000. I just said that's strange I already have one and I know another guy up the road who has one and your mower makes 3 , he just shut up then.
My brother just went to his local mower shop with a newish 2 stroke Hitachi chainsaw that had done very little work, all that was wrong was it was idling too fast ,they told him the chainsaw was beyond repair and parts are no longer available and said he had to buy a new chainsaw ,there was nothing wrong with it, just adjusted the idle .
I know of lots of stories from shop owners and Mechanics making up rubbish and over charging.
If you search on eBay " briggs 3.5 carburetor diaphragm kit " you will find the kit for $2.65.
Good that the mowers working now and I've had lots of mowers on 50 psi last many years cutting grass , time wise it's always cheaper to buy a working mower but then you don't learn much about them.
