The Ultra XP 2bbl carburetors feature all aluminum construction for nearly 50% weight savings over their zinc counterparts, contoured venturii inlet for unobstructed airflow, screw in air bleeds for easy fine tuning, black anodized fully adjustable billet aluminum metering block and baseplate, high capacity fuel bowl which features 20% more fuel capacity to eliminate starvation, integrated fuel shelf to minimize fuel aeration and internal baffling to control fuel slosh and a centered air cleaner flange for improved airflow and performance. Other notable features include wedged floats, knurled hand adjustable curb idle screw and down leg boosters. Ultra XP 2bbl carburetors are approved for use in NASCAR® Mid-West/West Coast Late Model Divisions and utilize the same venturii and throttle bore dimensions of the classic 4412 2bbl carburetor.

Ten Stars
I only use the left two colors but I expected that since I wasn't sure which one(s) would work. They are a great concealer of dark circles. I use the lightest one on the bottom and then touch up with the darker of the two. They don't look caked on and, in fact I can wear them alone without any foundation or powder on my face! And, they lay on top of the fine lines, hiding them somewhat. The brush is great for applying. I have tried many concealers and this is the the best by far.

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating. Why I gave it 5 stars: Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin. Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn. No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners. Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind. If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!

Great value and very practical
Style: SPF 50, Size: 8 Fl Oz (Pack of 6)
This sunscreen is a great value for the price. The SPF 50 protection works well and the lotion applies smoothly without feeling too greasy. It absorbs nicely and provides good coverage for outdoor activities. I especially like using these bottles to refill the sunscreen dispensers at my Airbnb for guests. It’s convenient, reliable, and affordable when you need multiple bottles available. Overall, it’s a solid everyday sunscreen and a very practical option if you need good protection at a reasonable price.
