Question about Garden
It will not start,put a new spark plug and fuel filter on,still will not start,i notice the primer bulb when depressed,does not come back to form,i guess it is not getting gas.
Depending on the OEM and Model Number of the Carburetor, it Sounds like the Fuel Filter Requires Changing, the Primer Check Valve is Stuck and Stopping the Primer from Operating, the Carburetor Filter/Screen is Restricted or the Carburetor Metering Jet is Stuck.
For the Fuel Filter;
The Following is a Basic Instruction File I made for Replacing the Fuel Lines and the Filter on Chain Saws and Trimmers. Any Input is Appreciated.
>>The Fuel Line is Pushed and Pulled (I Use Long Needle Nose Pliers) Through the Small Hole Until the Hose is Out the Fill Hole about a 1/2".
>>You can Also Use a Coat Hanger with a Small J at the End to Hook the Filter in the Tank and Pull the Filter and Hose (if Detached from the Carburetor) Out the Tank Fill Hole Enough to Replace the Filter.
>>Then Attach the Filter and Pull the Hose Back Until the Filter Lays at the Bottom of the Tank Just Below the Fill Hole (or so it is in the Bottom of the Tank and will Rest in the Fuel Mix when Turned at Common Angles the Unit May be Turned to During Operation.
>>**Hint: Use Plenty of Spray Lubrication at the Small Hole as you are Feeding in the Hose. It Slides Easier.**
For the Other Possible Causes, Soak and Clean the Carburetor.
>>The Following is a Basic File I Made for Cleaning Carburetors. Any Input is Appreciated. Even though the Carburetor LooksClean, the Internal Passages May be Restricted with Varnish that GasCauses to Build Up over Time.
>>Spray Cleaners Remove this Varnish in Layers, so Soaking is the Only Sure Way to Remove ALL this Varnish.
>>I have Found that Most People can Use a Breakdown/IPL and Disassemble the Carburetor Enough for Proper Cleaning.
>>Remove Any Adjustment Screws that Go Into the CarburetorBody. The Welch Plugs Do Not have to be Removed.
>>If you are Able to Remove and Disassemble the Carburetor and Keep the Gaskets Intact, then Usually these Gaskets can be Reused. The Only Parts you May Need to Replace are the Needle Valve and Metering Pump Diaphram.
>>If you Order a Kit, then Replace All the Old Components with he New Ones in the Kit even if the Old Parts Look Good.
>>Once Disassembled, then Soak the Carburetor Body and Parts in a 1 Gallon Can of Gunk Carburetor Cleaner Overnight. The Can has a Parts Tray Inside it for the Small Parts.
>>Once the Carburetor and Parts are in the Cleaner, you can Replace the Lid for Safety and to Prevent Accidental Spillage.Then Blow Out the Passages with Compressed Air.
>>***(Do Not Use High Pressure Air for the Zama Carburetors, they have Check Valves for the Primer and these
re Usually Blown Out of the Carburetor if Not Careful. Allow the Zama Carburetor to Set on a Drip Pan and Dry)***.
>>****All the Carburetor Adjustments are the Same for LawnMower and Trimmers.
>>If the Main Air and Idle Air Mixture Screws are Side by Side on the Side of the Carburetor, then the Idle Air is Nearest the Engine.
>>****Turn the Idle Air and Main Air Mixture Screws In Until SNUG **Do Not Jam** Then Reverse Both Screws 1 1/2 Turns. Holding the Throttle Full Open, Start the Engine. Turn the Main
ir Mixture Screw Clockwise Until Proper Revs are Obtained. Occasionally you May have to Turn this Counter Clockwise to Achieve the Proper Revs. Now Allow the Engine to Idle. Set the Engine Idle Screw (Not Idle Air) so the Engine will Stay Running if Required. Now Set the Idle Air Mixture Screw so there is No Hesitation when Throttling from Idle to Full Throttle. Reset the Engine Idle if Required.****
>>If you have Questions, Please Ask. The links above Provide Good Directions on Cleaning the Carburetor. Make sure you use an Compressed Air to Blow through all the Carburetor Passages to make sure they are Clear.
