Craftsman 917384370 lawn mower Parts

Yes. For a Craftsman walk-behind mower model 917384370, the right gas helps it start easier, run smoother, and avoid carburetor and fuel-system problems. In most cases, regular unleaded gasoline is the correct choice; avoid old fuel and minimize ethanol when possible.

What gas to use (best practice)

• Use fresh regular unleaded gasoline.
• If ethanol-free gas is available, it typically stores better and helps reduce varnish buildup.
• If you use E10 (10% ethanol), keep it fresh and do not store it long-term in the tank.
• Do not use “race fuel” or high-octane fuel as a fix for starting or running issues.
• Never use gasoline that smells sour, looks dark, or has been sitting for months.

Quick fuel guide

Fuel type	OK to use?	When it makes sense
Regular unleaded (fresh)	Yes	Everyday mowing
E10 (fresh)	Yes	Common pump gas; use quickly
Ethanol-free (fresh)	Yes	Best for storage and fewer fuel issues
Old/stale gas	No	Drain and replace

If the mower runs rough after refueling

• Drain the tank and refill with fresh gas.
• Check the air filter and spark plug condition.
• Inspect for water in fuel (surging, sputtering, won’t start after sitting).
• If the blade hit something, check for vibration and stop using it until inspected.
• For seasonal storage, follow a proven storage routine like how to winterize a lawn mower.

Why it matters

Fuel quality is one of the biggest factors in walk-behind mower reliability. Stale or ethanol-heavy fuel can leave deposits that restrict the carburetor, leading to hard starting, surging, and stalling.

For a Craftsman walk-behind mower like model 917384370, the model number is typically printed on a product ID sticker on the mower deck. On many Craftsman decks, that sticker is on the rear of the deck near the lower handle mounting points.

Where to look on model 917384370

Check these common sticker locations on the mower deck:

• Back (rear) of the deck, between the lower handle mounts
• Rear-facing surface of the deck just above the discharge opening area
• Side of the deck near a rear wheel height adjuster bracket
• Top of the deck near the engine mounting area (less common)

What the label looks like

Most Craftsman walk-behind mower ID labels include:

• Model number (example format: 917.XXXXXX or 917XXXXXX)
• Serial number
• Sometimes an engine model/type/code (engine label is usually on the engine itself)

Quick ID tips

• Wipe dirt and grass off the deck; the sticker is often hidden by buildup.
• Use a flashlight and look at a low angle to read faded printing.
• If the sticker is damaged, take a photo and zoom in to read it.

If the sticker is missing or unreadable

Use these practical workarounds to confirm the correct parts list:

• Match parts by deck and handle hardware you can see (knobs, bolts, brackets)
• Compare your mower’s blade mounting setup (adapter style, bolt pattern)
• Start with common deck hardware and confirm fit by diagram placement

What you can still identify	Where to check	Why it helps
Deck hardware	Handle mounts and rear deck area	Confirms chassis family
Blade mounting style	Under the deck at the blade	Confirms adapter and fasteners
Handle knobs/bolts	Upper and lower handle joints	Confirms handle assembly version

A common part tied to blade mounting is the lawn mower blade adapter 581547901, which helps connect the blade to the engine crankshaft.

Why it matters

Using the exact model number (like 917384370) prevents ordering the wrong Craftsman mower parts, especially for blade adapters, brackets, and handle hardware that can look similar but mount differently.
