I don't recommend using carb cleaner. It will damage the plastic parts. If you must clean carbs use Gunk Carb and Parts cleaner Kit and soak the carbs stripped down.
Check that the choke is closing fully. Check that the carbs are all getting fuel. Of course if you only have one carb. You did not state which model you have.
Use a spark tester and check the sparks. If you have old plugs then replace them. The throttle should be opened to get the start condition.
Try disconnecting the stop button to ensure that that is not causing your problem.
Old gas or water in the gas can also be an issue. Fuel treatment wont help. When you fill with fresh fuel don't add it to old fuel. Use Stabil in the tank to keep the fuel fresh and to minimize build ups in the carb/carbs.

thanks james

i oppen up the carb when i use carb cleaner, i have one carb my motor is an 80s model suzuki its a pull start i think the problem i have is from the oil fuel mix

its my first engine so i dont know much about mixing and what to do before starting the motor,

my fuel tank is a 25ltr tank portable, so what i did the last time was i pumped a litle fuel and puled the choke and gave it a few try's and it started well someone told me that the small motors are always like this , sometimes it runs even i i pull start with my teeth lol ( i call it hendrix style ) and sometimes it just takes time till it starts

i rebuild my 1979 glastron i replaced everything on it , stringers, transom, gel coat, did some fiber work , paint, carpet all lights and hardware, so now its engine left i hope after doing all this it will be fine.

all is good now thank you guys alot
