Starch is a carb.
It depends on your skill level, what engine you are replacing with what engine, what vehicle you are removing from and putting in, tools, and how much time you have. Is it EFI or carb? Are you going from carb to EFI? Carb to EFI? It can take a day or it can take a year lol.
There are a few ways to clean a small engine carb. One is the simple way of applying the coke to the carb and spray a small amount of carb cleaner to the carb. Number two is to take the carb off and take it apart and buy a rebuild kit and rebuild the carb.
Turn gas off, remove carb. Take bottom of carb off via 4 screws. This called the bowl. Check to make sure float moves freely, is so, leave it alone. Take the keys out and soak them for ten mins in near boiling water and carb cleaner. Then take small stiff wire and make sure all the holes on the side of the jet tube are not obstructed. Do the same for the jet it self. U should be able to see through it. Also soak the carb overnight in carb cleaner. If the jets can not be cleared buy a carb rebuild kit for $15

Remove the carb and take the bowl off the bottom. Remove the jets and soak in carb cleaner. Make sure you can see daylight through them.
The problem is your carb. Most likely you have an Edelbrock Qwiksilver. The carb is fine,but not for this application. In the case of both the 400 and 620, the carb was excessivelylean in order to make it through EPA emissions. The cure is to swap the carb with a KEIHIN FCR. You can get a kit from sudco.com or rig one from a motocross bike. A 620 with a Qwiksilver may take 12+ kicks to start. A 620 with a FCR may only take 3 kicks to start.
take off the carb. on the botoom of the carb is a bowl take screwsa out and the big jet in the center is the main jet. remove with a flathead screwdriver
adjust your idle screw on the side of the carb its the one with the spring on it. if that doesnt help then take the carb apart and clean it to make sure theres no dirt in it.
I would take air cleaner off when engine is cold and then push the gas pedal to the floor twice and then look unto the carb. and make sure the choke plate on top of the carb. is closed. You should not be able to see into the carb if it is closed. If it is closed then take your finger and open it up and hold it open. take other hand and pump the gas throttle wile looking into the carb. you should see gas spray into carb. if not then the excelarator pump in carb is bad. You should also check the point gap (dwell) in the dist. Could have a bad coil. NEUTZ
If you are getting gas into the float bowl, I would say your jets are clogged. Take the carb off, pull the idle and main jet out, soak them and blow them out with air. Make sure you can blow through them before reinstalling them in the carb. This should solve your problem.
