Different carb types for B+S 5hp model 130202

[oldbeagle]

Can someone provide some info on the different carb types for the standard flathead B+S 5hp engine? My model is a 130202. My engine has the pull-out slide choke and used the flat mostly square metal air cleaner.

There was a later type that used a lever for the choke and used a cylinder type air cleaner. This seems to be the best model because it appears to be less restrictive around the choke area. The gas cap also angled out a bit to make it easier to fill.

Then later, there was the carb that uses a plastic big gas cap and IIRC nonreplaceable jets. It also uses a flat box-type air cleaner that uses a paper filter.

Are there model or series numbers for these carbs? I'm looking for the second type I described.

Give me the rest of the engine numbers and I will see what I can do for you concerning carb types.

The tank mounted ones?

they're called PULSA JET carb, they come in two flavours..
rotary choke (the one you want) and slide choke.

But the airfilters are interchangable so you can mount the flat tin can filter on a slide as well as on a rotary choke..
(that's what I have on my 1302)
and vice versa.

Fig C is what I currently have and what I've seen on pretty much any old 5hp engine with points which mine still has.

Fig B is what I call the 'better' series and is what I'd like to upgrade to.

Fig A is the newest nonadjustable type I think and uses the flat paper filter. I dont think this carb is good for modifying, no?

This is not exactly what you asked, but here is what I did with my Daughters 4hp briggs after giving up on the pulsajet. It is a pz19 carb, $16.95 total from ebay, with a custom made, wood intake manifold. Wood because i don't have a welder yet. Runs really good, idles nice with good response.
