     I got an old ariens 724 from my grand father and in runs ok but the carb needs a rebuild and it needs a new float. the tag on the side of it is gone and i need to figure out what the number was. It is an ariens 724 7 hp model #924075 ser# 001301 # on carborator reads 283 9J25. Any help would be great. thanks

The base engine for that model was 130210K so anything close will work.

You can use any generic kit for an H-70

Float 631023 or replacement numbers 632019  632019A

I get lots of those older engines with carbs messed up with "varnish" and lots of sunken floats.  Rarely is a full  kit needed.  All that's usually needed unless it was rusted or white rot is a float gasket, O-rings, and a needle seat.  Better to put the money into a can of solvent for an overnight dip. 

i know the float has a crack in it as it was half full of fuel. I had the whole upper half sitting it carb cleaner for a while and cleaned out all the pasages.  I was just looking for a kit with new seals and gaskets and then a float. hopefully those numbers you gave me will do the trick.

the was vertually no rust in the thing, but i know he used to use a really old metal gas can to fill the thing so that probibly didnt help things.

baadlee! make sure you inspect the brass nut that holds the float on,this is the high speed jet and has small passages that need to be clean.use a small wire and plenty of carb cleaner along with compressed air .once you have it back together and running put the appropriate amount of sea foam in the fresh gas,start it up and run it at high speed and spray small amounts of sea foam into the carb. the engine produces the draw and the seafoam supplies the cleaning agent to help clean all the passages that the cylinder is drawing fuel thru. this will really clean it out.you can also take the plug out and turn the engine over by hand till the piston comes up on the compression stroke.leave it at the high spot and dribble about 1/2 oz of seafoam down the sparkplug hole.put the plug back in and let it sit for a couple of minutes and then start it up.you will see smoke like the dickens till everything is burned out the exhaust.seafoam will really help clean things up and is much better for a running engine because it has some lubrication qualities that choke or carb cleaner doesn't have.seafoam also has fuel stabilizing ability and can be added to your fuel can everytime you fuel it up.

Thank you guys for all your help. I was able to find a rebuild kit and float and it now runs great.
