Trouble shooting carburetor issues


after cleaning and rebuilding carburetor issue = [ The engine will only run if the choke is on problem] = Trouble shooting step #1 - Make sure the low speed idle mixture screw is open wide after starting the engine before turning the choke off, If there is no verification that the low speed mixture screw is allowing the engine to run rich or lean at low idle after turning the choke off, than this usually means that the low speed idle passage way still has a contaminated fuel block that is not seen while rebuilding or cleaning the inside of the carburetor. This low speed passage way problem lies under the welsh plug located on the side of the carburetor near the low speed mixture screw on most carb's, some of the new style carburetors do not have a low speed idle mixture screw and are pre set or pre fix from the factory and only have the welsh plug.


Step #2 To clean and repair the low speed idle passage way - you must carefully remove the welsh plug then use a wire drill along with some carb cleaner to poke threw the epoxy like contaminated fuel block in this small Chanel that feeds the mixture screw the gas on the side of the carb. under the plug, after this passage is poked completely clean threw, a new welsh plug must be pressed back in then sealing the welsh plug with nail polish to stop leaks! nail polish is vinyl acetone base and will not melt or brake down with gas once dried out.


Most of the time when the low speed idle passage way has a block I will take the carburetor and throw it in the the junk and order a new one and do not recommend step #2 in less you have good mechanical skills.


[ The engine will only run if the choke is on problem]

The resound the engine will run with the choke on when the low speed passage way is blocked is because the choke creates a large vacuum and pulls the gas up into the hi speed jet inside the carburetor, the engine gets just enough gas to allow to run but, not run properly, so I hope this helps.
