Aluminum 4150 Carburetor 850 CFM Double Pumper Mechanical Secondary

Here's some more details, only complaint is the booster are not all evenly installed. Other than that I'm impressed. This 850 dp has 30cc pumps, down leg boosters, low speed and high speed bleeds, even the metering block is tapped for bleeds( think the block would have to be drilled if want to install jets) , progressive throttle linkage, brass floats, power valve up front, plug in secondary.4 corner idle. 14mm x 1.5 fuel line threads, If you get one take it apart and clean it, I found a few matching chips inside. None of the jets are labeled for size, and make sure every jet/screw is tight. Adjust all air screw's evenly( some were 1/4 turn some 3/4 out.and set the idle screws.all said for the price if you can do the basics I think it's ok for the price.

The media could not be loaded. I have purchased 2!! I was excited how they were “supposed” to operate out of the box but NO? Leaking from boosters and needle/seat! Float levels way too high. I’m retired disabled veteran who has been scrimping/saving and trying to finish my father’s tribute for 13 years! I read about these and rolled the dice instead of buying two “big name” carbs, now I’m lost?

not good for me carb looks good idle ok but linkage loose .

Youre not going to find a better ChinaCarb with these mods and parts. From what I can tell all Holley stuff will screw/bolt on to it or viceversa. If you dont know how to tune a Holley or watch videos you may not want to go here or go ?X the price with EFI.

Needs better description on what your getting

Nice to look at
