Another good looking premium guard made filter, thanks!

It’s a Purolator L20195. Now, I never usually use Purolator stuff (even though I actually like them aesthetically and some of the older stuff they made), but for $4 and available locally, it’ll do just fine. The L in the model number is kind of the lower mid tier filter. It’s above the white...

Efficiency and build quality is probably very similar between the two 😂

I upped a buddy’s lawn mower to the only filter in stock around me, coincidentally also the biggest filter it can fit. Hood just kisses the filter when closed, perfect.

I think we have a winner for most beautiful stash! The HPL 😍.

I would just vacuum or blow out and put it back in.

It ran quite rough. Seemed like it was running on about 1 1/3 cylinders, with one being incredibly rich.

Yeah, it's kind of a crappy design, but o well, rebuild time.

Welcome to the site!

I'd agree with that sentiment. I need to go back to just running every machine I have dry at the end of the season rather than using fuel stabilizer, it never works in carbed engines IMO, only EFI. This engine gets treated like a queen with a really early maintenance schedule in a mild climate...

That's about what I've read about these Nikki carbs. I thought about replacing w/ aftermarket chinesium, but I would rather just rebuild with a decent quality kit. I hopefully won't have it that far apart, but will run some Valvoline R&P if I notice any oil burning after its all said.

From what I’ve read and seen, there’s a small gasket that allows the gas to split off into each cylinder. Over time, it swells or becomes clogs and then the flow gets diverted to mainly one cylinder.

Aslong as the head gaskets come off clean with no tearing or anything like that, they can be reused.

Looks like I will be replacing both head gaskets along with rebuilding the carb and replacing the fuel pump. Carb has one cylinder running very rich, an unfortunate result of a bad double barrel Nikki carb design.

I’ve been thinking this. Motor was swapped on two summers ago, only 5 hours on motor, cooling good.

Engine is a 20HP Briggs V-Twin Intek. Model #407677. I brought my mower into service a few weeks ago. Changed the oil, oil filter, and air filters. Mowed my yard, ran a little rough. I checked the plugs, one looked perfect, the other one was black as can be. Swapped out the plugs, right...

Looks good. I was not aware HPL did oil analysis.

I agree, it’s a very good price for their top shelf oil. It makes it a very hard decision between Castrol Edge EP and Valvoline EP with the pricing being so similar. Before, the Valvoline EP was my go to for top shelf oil for the price. Hmmmmm, decisions decisions.

Found the 25k variant on rollback at Walmart, good price. Valvoline EP was the same price.
