Thanks. That may help. The tractor would originally have had 7.25hp. Is it possible that I'm dealing with the original carb for the tractor?That appears to be a Briggs and Stratton flow jet carb.
They are called large two piece flo jet or small two piece flo jet. The are expensive now days, but kits can be obtained reasonable. (from ebay)
May not even need a kit if you can get the bowl removed without ruining the gasket. Just give the carb a good cleaning.
Look at this link and if you are going to kit the carb take note of the disassembly/assembly instructions. The carb can be easily damaged if the procedures are not followed in steps. Hint a jet tube has to be removed before the bowl can be removed. (and they have to go back together in a step sequence. (for the jets) I've re-built them with good results.
Start at the top of this link page a scroll down looking at the pictures to get in the ball park and to ID you carb.
Those carbs were quite common on the older Horiz shaft Briggs 3.5hp and up. the large flo jet was for the larger engines at about 8 hp and up.

I've thought about that but I'd really rather keep a vintage motor in it. I'd love to find one of the bigger Clinton engines.I have 2 flow jet carbs,both were unmolested with functioning govenors,Got rebuild kits on amazon,very happy with them.Yours,i would be a little lost if stuff was missing.It might be cheaper and easier to install $99.99 6hp Predator motor .
Thanks for the info. I'm learning something new here. Although, now I really don't know what I have. There is no auxiliary PTO so I'm really wondering about the possibility that the blower housing has been replaced. I'm going to measure the bolt pattern on the carb to see if I can maybe pick out a new one that way. Beyond that, maybe I should start looking for a different engine.I have a few old B&S engines that were similar to what that tractor had factory..
Old model 14 die cast ones,I think the model numbers were 142302--they are about 5-6 HP,and they have flo-jet carbs,but both have air vane govenors though,which they only used one year on those tractors,then switched to engines with mechanical govenors,which respond quicker and better to sudden load changes..
Many old Briggs like yours had flo-jet carbs factory,some did use the pulsa-jet ones with the carb mounted on top of the fuel tank,but most tractors used the float style carbs..
I have swapped flo-jets on engines that had pulsa-jets,you just need the right one,there are "large" and "small" bolt patterns and the venturi is bigger on the large ones..
I "think" 3 to 5 HP engines use the smaller ones and the 6-10 HP ones use the larger version..you can determine what carb came on the engine factory by the model & code numbers..
Going by one of my service manuals that engine was a 5 HP ,originally came with a pulsa-jet carb and it also states it should have an auxillary PTO that runs off the camshaft,for reverse on a roto-tiller or snowblower ,so that is likely what it came off of,and someone swapped the flo-jet carb onto it..
There is also the possibility someone just stuck a complete blower housing off another engine on it when the recoil failed ,that often leads to getting the wrong parts,as those housings fit a lot of different engines..it wasn't the best idea Briggs had,to stamp the numbers on that part for that reason..
