"I can't use two mowers at once"....ha!
Also I didn't know that lawnmowers were still carbourated. I pretty much know nothing about small engines. Because idiot.

It's barely a carb. Has no moving parts. Basically just a siphon.

There's actually a new small engine Kinja blog: pullstartmyheart. I've sort of agreed to write a thing or two for it.
Also, lawn mowers are still carbureted because nothing else is really as simple or adaptable for a single cylinder. No good way to do electronic fuel injection at low cost, and mechanical displacement fuel injection won't idle and is temp-sensitive.
The one in his ad is a 4.0HP vertical shaft Briggs, which has a diaphragm (not float bowl) carburetor of a design Briggs has been making for ~50 years. It's solid, we'll leave it at that - though if you were to be a dumbass and run ethanol gas in it and leave it sitting, there's a little pre-fueling bowl in the top of the gas tank in which there's a screen that would clog with scum. Not fun.

Well, there's one semi-moving part - the diaphragm. I haven't worked on the 4HPs that often, but the 3.5s? Yeah.

Yeah I saw the new blog. I just didnt think I have anything to contribute. I don't own any small engines and have no knowledge about them really. Thanks for the information though, I appreciate it.

I would have mentioned power-to-weight ratios. 4HP on a 50 pound mower means a p/w better than an FR-S or Mustang V6.

Yup, that ended up being the problem, the diaphragm. Once I put a new one in, fired right up.

Damn, you're right

Generally, they'll get to run if not well with a bad diaphragm as long as you pre-prime them from dry with a little sniff of gas down the throat. The reason being, the little bowl in the tank has to fill, and a dead diaphragm doesn't have the stones - in my experience. The other killer is funk *in* that little bowl clogging the pickup screen.
Less prone to get funked, in my experience, but a little less obvious to un-funk than the float-bowl verticals.

Yeah, before, it would catch for a few cycles if I primed the hell out of it, then die. Didn't have to even prime after the fix.
The kit came with a new spring and filter, so that may have helped as well.

I totally mis-read the title as "Troopers", hence the following video.

maybe they're for spares. The pushmowers and stuff I can sort of see...but how does on accidentally acquire a 2nd ride on mower? lol.
