Powtol Mckin D140 D130 L120 LA145 Tune Up Maintenance Service Kit fits John Deere LA135 LA120 LA130 LA140 LA150 Lawn Mower Parts

What It Is

This Powtol tune-up kit bundles a spark plug, air filter, fuel filter, and oil filter (or equivalent) for routine maintenance on select John Deere 100-series lawn tractors. It’s designed for owners who want a single, low-cost package to refresh engine performance and extend mower life.

Fitment & Compatibility

Before buying, verify your mower model and engine type. This kit is listed for John Deere D100/D110/D120/D130/D140/D150/D155/D160/D170, plus LA-series models (LA105/110/115/120/125/130/135/140/145/150/155/165). It also fits L100/L108/L110/L111/L118/L120/L130/LA145. Not all models in these series share the same engine – for example, some D100 variants use a different spark plug or filter. Check your engine’s make (Briggs & Stratton, Kohler, or Kawasaki) and compare the included filter part numbers (commonly air filter AM125424, fuel filter AM108733, oil filter AM125424 – but verify). Measure your existing air filter and oil filter dimensions. This kit is an aftermarket alternative to OEM parts; it may not match the exact OEM fit for every engine variant.

Key Things to Know

• Quality is decent for the price – components are functional but not premium. Spark plug gaps may need adjustment (typically 0.030″ for most engines).
• Installation is straightforward – swap filters and plug following standard procedures. No special tools required beyond a socket set and a plug gap tool.
• Common gotcha: The oil filter may not fit all engine brands. Some users report it being too small or having a different thread pitch for Kohler or Kawasaki engines. Check your current filter’s thread size and diameter before committing.
• Fuel filter orientation matters – ensure the arrow points toward the carburetor. Replacing it without draining the tank can spill gas.

Should You Buy It

This kit is a solid budget option if you own a common John Deere 100-series with a Briggs & Stratton engine and want a quick, affordable tune-up. It’s not ideal for picky owners who demand OEM-grade components or for mowers with less common engines. If your model lists multiple engine options, verify compatibility first – otherwise, you may end up with a filter that doesn’t fit.
