How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Get your can and spray the liquid on the carburettor. Make sure you don`t go overboard with spraying the liquid as it may end up harming the device. Rest assured that WD-40 is potent enough to work its magic even if it is sprayed decently on the carburettor.
If you opted to buy a chemical dip, you can place your carburetor parts in it to soak. Alternatively, you can spray carb cleaner throughout the various channels in your carb (such as the spots where the jets, float pin, and air and idle screws were). Also spray cleaner through any dirty jets.
It`s like a “VIN” for your carburetor and should be hand-stamped on the front of the choke tower to the right of the vent tube on most typical Holley carbs. The list number typically is four to six digits long and may or may not have a suffix number behind it.
To arrive at the most appropriate carburetor choice, there`s a basic formula: engine displacement multiplied by maximum rpm divided by 3,456. For example: a typical 355ci small-block—a 0.030-over rebuild—with a 6,000-rpm max engine speed would work well with a 616-cfm carb ((355 x 6,000) 3,456 = 616.32).
An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.
Pulling the choke lever provides proper fuel-starting mixture when the engine is cold. When attempting to start a cold engine, pull the choke lever outward to close. Slowly return the choke to the open position as the engine warms. Leave the choke in the OFF/OPEN position when starting or restarting a warm engine.
Lawn mower upkeep is easy with WD-40® Multi-Use Product. Spray blades before mowing to keep them clean, sharp and corrosion-free. Your post-chore clean-up will be fast and simple; wipe down the blades, and your lawn mower will be ready for its next spin around the green.
WD-40 removes carbon residue and keeps moisture away from spark plugs and spark plug wires. WD stands for Water Displacement, so if your spark plugs are wet or you need to drive moisture away from ignition distributors, WD-40 will do the trick.
Tip: Use WD-40® Multi-Use Product to protect lawnmower parts from rusting and keep its wheels turning smoothly.
Use Carburetor Cleaner

Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.

With engine running:

Carburetor: Spray to both ends of the choke valve shaft while working choke by hand. Spray down and around the carburetor throat to remove deposits from the throttle plate area. Do not spray down carburetor throat with engine off.

Spray liberally with carb cleaner – trying to direct the cleaner into the jets – and leave to soak for a few minutes. Use an air line (or a can of pressurised air, sold as an `air duster`) to blow through the jets. Repeat the previous step and this one until you can see no more gunge.
