Engine Filter – Part Number: 298090S
$6.40
In Stock
Engine Filter
Part #298090S
This is a round, inline fuel filter with 0.25-inch nipples, used in a variety of lawn and garden equipment. It is sourced from the original equipment manufacturer and has the capability to filter out particles as small as 150 microns in size. The filter is designed to remove any dirt or debris in the fuel to avoid contaminating the engine. Over time, it is common for the filter to become clogged with dirt/debris or damaged, resulting in less fuel entering the engine, engine misfiring, stalling, and overall lower performance from your equipment. To replace the faulty fuel filter, first disconnect the fuel lines with pliers or a clamp tool and then pull out the old filter. Install the new filter into the housing and reattach the fuel lines to complete your repair.

Bad governor

Look on YouTube for video's on how to replace a Briggs governor. There are several there. My favorite, with best explanation, is, "Easily Replace Briggs Governor Gear (V-Twin Intek Engine) with Taryl". https://www.youtube.com/watch?v=wn3eanGxSEA&t=152s.

Taryl (probably not his real name) does a very good job of showing step-by- step the whole procedure, along with some additional hints/tricks/techniques of value.

Not including oil and filter, I spent less than $50 for a new governor, gasket, and drive shaft seal. That's all that is really necessary to replace is those three parts. That is, unless pieces of the old governor tore up a gear, valve, or something else. Inspect everything! {I was lucky and only the governor was destroyed}

One word of note. Be sure to clean out all of the debris from the blown governor. Be sure to remove the spark plugs and carefully rotate the drive shaft while looking for nooks-and-crannies where debris can hide. I tried to use a magnet to help, but it didn't help much, even though the block is aluminum.

Good luck.
