Review on 🚗 ALAVENTE 1 BARREL Carburetor Carb for GMC Chevrolet Chevy 292 L6 Engines 4.1L 250 and 4.8L 292 2007-2016: Reliable Automatic Choke Carburetor for Car Restoration & Garage Repairs by Jay Lee

UPDATE: 11/15/20 Waited over 30 days for parts to arrive, emailed the company and they 'lost' the shipment and they had no delivery information . They then suggested that I contact Revain and ask if Revain would send another carburetor as a replacement. I feel like clowns. UPDATE: 9/28/20 I contacted the company through Revain and asked if I could purchase replacements for the damaged parts in my photos. They responded to my inquiry within about 20 minutes and very generously offered to send replacement parts after confirming what I needed. This is outstanding customer service, especially for an item under $100. After countless fiddling and adjustments, the truck's engine is still throbbing. This happens at all speeds. Loaded, empty, all gas conditions except coasting, which seems to reset the cycle, and seems like it wants to do it the other way around too. I'm not saying it's the carb that's causing the pulsation, it's the clutch and flywheel that are the next likely culprits, but they're only a few years old and have less than 10,000 miles on them. I will update again if anything is needed. Update I'll preface this review by saying I'm not a mechanic. I have owned and worked with Chevrolet 292 in line engines for over 10 years and I have no idea how many miles the engine currently has on the truck but I do know how it is supposed to work and this carburetor is very close to being picked out of the box to become . I really need this thing to work so I had to make it work. It's got a lot of stuff I never had on my old Rochester Monojet. It has an electric choke and a vacuum tank that looks like it keeps the choke open while the engine is running. It has holes, a manifold and, I suspect, an auxiliary vacuum line that has a constant voltage of about 10 in/RT. It looked decently packaged, the box was lined with thin foam rubber, but the mixture idle screw bent on arrival. It was bent so badly that it became unusable as it hit a pin directly above it and would not turn. This is not a genuine Rochester Monojet carburetor but is a very decent replica. You cannot get some items very easily. The idle mixture screw is one of them. I had genuine Rochester parts on hand and substituted them. It seems to have worked but I'll try to contact the company anyway to see if they can send me a replacement screw. After replacing the idle mixture adjustment screw, the engine started immediately, then fuel began to flow. So, float level adjustment, huh? no This thing that looks like a hand typed all over is holding a ruler. It's called the Power Piston Block and is another part that cannot be replaced with a Rochester. I'll ask if they still have one of these. I would even pay for it. I was able to very carefully take a small hammer, some needle points and a good deal of luck and shape it. As long as it works The truck moves but the idle doesn't drop below 1000. Not that it's really necessary, it would be nice. Not sure if it's because the recently removed power piston assembly doesn't have the exact same geometry as the one that came out of the sweatshop. intake manifold. I think at some point I'll try converting it to a manual accelerator, but for now I just leave the electric accelerator with no power and the truck doesn't look like it's going to choke, but it could be the vacuum tank holding the accelerator . open, i'm not sure yet. He doesn't feel stuck, he just feels kind of held back. Maybe I need a bigger plane? The size is not stated on it. This carburetor has no specs or specs so I can't decide where to go next. I don't know how to accurately describe the pulsing of the transmission. It happens at very light throttle, like you're just maintaining speed on a flat road, and there's a little ripple. It starts out small and can escalate to a harsh tug, a throbbing clank if I don't do anything. When I accelerate I don't feel like it's happening. For example, I haven't ridden higher revs in 2nd gear for a long time, but we have a lot of steep climbs here and it seems to pull pretty smoothly under acceleration. I'm not sure if it's a fuel issue or a transmission issue. I also think I may need to adjust the accelerator pump cup size. It feels like I'm not getting what I'm supposed to get when I hit the ground. Again without technical specifications, only barking in the dark. I bought it thinking it might be better than rebuilding Rochester. I can still drive, but it took me a bit of tinkering and struggling. If anything else happens I'll definitely update
