what if the carb i haz 4 the lawn mower seems to not hav any screws on it at all?

@megaman5043 If your carb. appears to have no adjusting screws then you have what is called a preset or nonadjustable carb. . All that you can do to it is clean and or rebuild if necessary . Follow my other videos to clean or rebuild it . On some of these carbs . though while there is no adjusting screws for high and low settings , there is a screw at the top of the carb that adjust the idleing . It's located on top of carb. next to where the flap where the governer rod hooks up.

@ESRepair - Will a WD-40 or a Liquid Wrench work as a Carburetor cleaner ???

[ESRepair]

@MrMilitantviper not to my knowledge. Those products are oil based lubricants and shouldn't be used in the carburetor. those can be used to lubricate the linkages connecting to the carburetor. there are alternatives like gumout but WhizKid should be on here later this morning after work. He'll have a better solution for alternative cleaners.-MrFixit

hi i need help not cleaning it but exaust is blowing out the carb and making lots of noise but i hear its to rich but i dont even think the neddle workes and i even checked the valve timing and the spark. please what can i do

[ESRepair]

@pimprock23 Hi , sorry that it took so long to reply , but I've been extremely busy. Read bottom post first. As I said make sure that carb is clean and working properly. Check for carbon build up behind valves. If all else fails , pull motor off machine and take oil pan off and make sure that the crankshaft gear that works the cam gear isn't broke , stripped , or key isn't sheared . If these problem exist then it will get valves out of time and cause misfire .

Thank you,

@ESRepair thanks for the tips but it turns out i make a custum exuast muffler and there was to much back Pressure

@pimprock23 Pull the top off of your lawnmower motor and get down to where you can see the flywheel key . If it's sheared any it will cause the motor to get out of timeing spark wise and this will cause the spark plug to fire at the wrong time and cause this problem . Check to make sure that both values are opening and closing right .Especially, if it's an OHV . Make sure valve seats and guides are alright . If OHV make sure that valve clearance are set right . Make sure that carb. is clean .

@andy42x You must have an older engine , since most newer engines today don't have the bowl screw . The screw under the bowl is the fuel adjuster for the main jet . The more that you open it up the more fuel goes in and the shorter you adjust it the less fuel goes in . Gad t hear that you got it going .
