Small engine primer bulb. The primer bulb draws additional fuel into the carburetor to help start the engine.

Walbro primer bulb. The primer bulb draws additional fuel into the carburetor to make the engine easier to start. If the primer bulb is leaking, replace it.

Champion spark plug (RCJ6Y). The spark plug ignites the fuel and air mixture in the engine's cylinder to power the engine. If the spark plug is has fouled (if the tip of the spark plug is burnt or damaged), the engine may not start or may run rough.

Fuel filter. If the fuel filter is clogged, it will restrict the flow of fuel to the carburetor. As a result, the engine may not start.

Tanaka leaf blowers are built for reliability, but like any gas-powered equipment, they need maintenance and occasional repairs. When your Tanaka blower won't start, loses power, or runs rough, the culprit is usually one of a few high-wear parts. Carburetors are the #1 failure — ethanol-based fuel gunks up the jets and float, causing hard starts or no-start conditions. Recoil starters, fuel lines, and spark plugs round out the most common repairs.
Repair Clinic carries genuine OEM Tanaka parts for carburetors, recoil assemblies, fuel system parts, and engine parts. Find your exact model number on the blower housing, then browse our catalog to get your Tanaka back to full output with the right OEM replacement.

The most common reason is a dirty or failed carburetor. Ethanol in modern fuel causes the carburetor's tiny jets to clog and the float needle to stick, preventing fuel flow. If the blower has been sitting for more than a month, drain the old fuel, refill with fresh gas, and try starting again. If that doesn't work, a carburetor rebuild kit or replacement carburetor is the next step. Check that you have spark (pull the plug and see if it sparks against the cylinder) and fuel flow before replacing the entire carb.
If the pull cord is stuck, won't move smoothly, or snaps during pulling, the recoil starter assembly has failed. The internal spring or pawls have broken. The entire recoil starter housing must be replaced — individual parts aren't serviceable. You'll need your model number to order the correct OEM starter, as the cord length and spring tension vary by Tanaka model.
Fuel lines on small gas equipment are typically 3/32" inside diameter for line between tank and carburetor, and 1/4" ID for fuel filler hose. Always reference your model number and owner's manual for exact hose diameter and routing. Using the wrong size can cause fuel flow restriction or leaks. Tanaka fuel lines degrade from ethanol and UV exposure — if your line is cracked or hardened, replace it with OEM tubing.
Not usually. A fouled spark plug is a symptom, not the cause. If your Tanaka blower has a clogged carburetor, the engine runs rich and fouls the plug quickly. Replacing the plug alone won't fix the underlying carb issue. Clean or replace the carburetor first, then install a fresh spark plug. For starting issues, always check carburetor condition, fuel freshness, and spark before assuming the plug is bad.
