Servicing and rebuilding an engine’s carburetors are not difficult. Doing so requires more patience and attention to detail than skill. Specifics vary by make and model, but the principles of carburetor rebuilding are the same no matter the engine brand, model or size. Here are some key points.
The jets must be disassembled. You can modify a screwdriver to do it, but I recommend purchasing the factory-specified jet removal tool.
Soak the carb bodies, float bowls and jets in carburetor cleaner. Use compressed air to clear out passages. Never ream passages!
Double-check the float height and drop measurements when replacing the float, inlet needle and seat. Improper adjustment leads to flooding (too high) or fuel starvation (too low).
