Time to invest in a $50.oo rebuild kit and clean that carb out good with laquer thinner and a blow gun after a good soak. Take everything you can out of it before soaking it in laquer thinner. Blow out all of the ports as soon as you take it out of the laquer thinner. A flux brush may be needed to dislodge some of the stubborn crud. Make sure you have a clean place to reassemble the carb. I like the dining room table. Great to have an understanding wife. Just don't bring that dirty carb in the house and expect the wife to be so understanding.

yeah especially at xmas supper time

35 you can go online and get the manual for that carb and run through the adjustment of the floats and other aspects after you clean it up as mentioned, check the fuel pressure too, no more than 5.5 psi, 5 is plenty.

Just looked back at the #1 post and see that the OP is 17, so I guess we'll have to say, "mom wouldn't be understanding"

When you do get it all cleaned up and ready to reassemble, you can say, "But mom, Big Al said to reassemble it at the dining room table ." I'll be happy to take the heat.

From another thread, but you might find it helpful:

Edelbrock Owners Manual covering 1403, 1404, 1405, 1406, 1407, 1409, 1410, 1411, 1412 and 1413- HERE. With the info from it and from Edelbrock Performer Series Carburetor- Complete Guide to Set-Up, Tuning, and Performance Jetting you can go about adjusting it for better performance.

If all you need to do is pull it apart and clean it, the basic p/n 1472 gasket set is about $10.00.

The whole rebuild kit is p/n 1477, shown It includes new needle and seats and accelerator pump piston along w/other parts not included in the basic gasket set.

Finally, you can get a p/n 1479 recalibration kit if the carb needs serious tuning. It does not contain gaskets or the parts contained in the rebuild kit.

This is a simple carb, easy to rebuild if you go about it carefully and take notes and/or photos and refer to the links above. I'd bet there's a video online that shows a rebuild of the Edelbrock carb so you might want to check youtube, etc.

Good luck.

If you are not using a ethenol treatment what you do is all for nothing.That stuff kills any carb and some gas lines, just eats it up. A lot of club members are all of a sudden having trouble with there carbs. They clean them and run a treatment and no problems. Any thing I have with a carb ( lawn mower, snow blower, weed wacker) gets an additive. I'de tell what to get but your not supposed to recommend any products on here. There are some good ones out there. Good luck.

Recommending a product isn't a bad thing here, unless you're tied to it in a commercial or financial way, making an endorsement for profit.

Whether or not the OP's problem involves Ethanol after effects, hard telling, but here's a picture of what you might find from long term Ethanol use, this is a marine carb, not one of mine.

In that case I bet blue Marine Stable would have helped.

Stabil has an Ethanol specific product I use in my skiboat, in Texas I get it at Academy and probably any auto parts store.

My grandpa worked at GM by day and repaired cars at night... he swore by Q-jets. LOTS of settings and such, so they take patience to get tuned right and can be frustrating, but when they're good, they're gooood!

I've never actually found a Q-jet to be frustrating. It just takes a cool head to take the time to run through all the 14 or so adjustments that are detailed on the sheet that comes with a good rebuild kit. It is time well spent.
