Band S 5 hp tiller want start

If it is old and isn't running without pouring gas into it I'd say the carb is dirty and needs to be cleaned. If you don't want to do that, you'll have to serve as the carb and continue to pour gas into it to keep it running. Your choice is obvious.

took carb apart changed seal emptied gas tank an d cleaned it out sprayed cleaned everything with carb cleaner put back together still want start plug is good still starts by putting gas in carb what else could it be

Clogged fuel line/filter???
Clogged cap vent???
Pinched, cracked, broken, fuel line???

What kind of engine in this machine? Did the carb have a float? Was it very dirty when you cleaned it? Sometimes carbs need to be soaked to get old varnish etc to breakdown.

yes i did change the diapram your right corb sits on gas tank ccleaned out tank cleaned carb put it back together still doesn t work on its own

how do u check if the vacumm is working on carb
