    • Works great!
Model: 1901R
I had to write a review for this because it's still running after a year. I'm new to carbeurated engines and the install was straight forward. Truck fired right up and is still running, was pretty easy to adjust and I'm sure there's more ways of getting it tuned even better with the included jets .But that's for someone who knows what they're doing so I won't mess with that yet. The price was a steal for me in comparison to a name brand carburetor, I'm not saying it will outperforms the name brand ones but if you're looking for something to just get your car/truck going, then this will work , for a stock engine at least. ... show more

    • Best carburetor ever !!!!
Model: 1901R
Thought that is was a lemon and then relized that I didn’t have the distributor advanced vacuum hooked up , and it is the best carburetor I have every had, works flawlessly you can let it set for 5 hours and come back and turn the switch and it’ll crank up with out idling down one bit !!!!!!!!!

    • An affordable replacement for sure
Model: 1901R
Linkage wasn't an exact match but could work around it. So far so good especially for the price.

    • Faulty Carburetor
Model: 1901R
Carb is faulty. Bought because I didn’t want to rebuild my old one but after installing and having 2 mechanics diagnose my 69’ Chevy I’ll have to have it rebuilt anyway because the float sticks and the bowls fill will gas
