Need help identifying Quadrajet

I have a quadrajet carb off my 86 4.3liter truck that i took off years ago for an Edelbrock 600, but gas is too expensive to justify that size carb these days. I need help identifying my qjet so i can get rebuild kits and throttle shaft bushings. The first number is 17086046, and following numbers are 2265 jpj. Mine has dual capacity pump but not computer controlled. Could someone please help me out

170 is the prefix, it started in 1976, not sure about the meaning of it
86 is for 1986
0 is the emission code
4 is the GM division of buick
6 is for the trans type. Even numbers are usually for automatic odds for standards

Take the 17086046 number to NAPA and let them look you up a kit.

The Buick part threw me a loop because the carb came stock on the truck, a Chevy? Some sites say Rochester doesn't always follow those labeling guidelines? Thanks for the suggestion about Napa, i'll be showing my face in there pretty soon. If anyone can tell me if its M4M or E4M or one of those i would appreciate it. Thanks!

After about '80 the numbers got pretty skewed. Your carb is original to that engine.

I have a similar carb, 17086047 from a 1986 4.3L V6 Sierra w/MT, 800 CFM. Date code: 0226, and “JPK” build code. Came w/74 jets x 55A primary rods; EH secondary metering rods on a “J” hangar.

Just use the carb number (17086046) you posted to get a kit (the other codes aren't needed to order a kit). The carb kit for it if using a Walker kit (sold at O'Reilly, etc.) is 151097.

Short wiki page on on the dual capacity accelerator pump Q-jet is HERE, other Q-jet carb info HERE.

Thanks I really appreciate it! 2 years ago, the Edelbrock was the best decision i made, i loved the power but now that fuel has reached 4 dollars in Florida, im going to love those tiny primaries alot more on my Qjet

I have purchased 2 QJet rebuild kits. Each from a different company. Both kits will rebuild all versions of the carbs (you just end up with a few parts left over and gaskets that don't work on yours). In fact I bought one today from O'Reilly's for $18. Have fun!
