Pull out the slide then lower the clip on the jet needle one notch. Then try two notches. This will richen the mid range response. Give this a try before trashing the carbs.

Go to the site below and you can download a free service manual PDF. The one you want is 47th from the top of the Suzuki list. Yes, I know that it is for '93 to '95 models. It is the closest I could come to '89 and 90% of the data doesn't change and it is free. For an exact match Google " service manuals suzuki " or go to
Also try your local library. Often guys will donate manuals to the library.

How to adjust a carberator on 1979 datsun 310 gx

Whoa. Classic stuff here and a definitely dying art.

The true scope of your question is above what you're gonna get from this forum. While I am familiar with and have done carb adjustments each carb is different. Too, this being 1979, this was in the early days of emissions ....there are going to be adjustments unique to maintaining low emissions least for 1979 standards.

To do this right you will need to lay hands on a "Dwell/Tachometer". You may need some feeler gauges and or properly sized drill bits. You will also need a copy of a service manual for your 310 in order to make sure you have instructions and specs on *all* the adjustments. The manual will also show you what tools you'll need (like feeler gauges and drill sizes ...they are often used to adjust a choke pull-off to get the proper opening). You may have to bend linkages and/or tabs to adjust settings. You might be lucky and find a copy of one online for free (usually a .pdf). Do some online research.

A BIG concern: if this carb is the original unit there is a *very* good chance it has worn out. What wears out on a 35 year old carb? The bushing areas the throttle plate pivots in. These "bushings" are simply holes machined in the main casting of the carb ...the throttle body ...and the shaft of the throttle plate rotates in these bushing areas. Over time, after thousands (millions?) of small back and forth motions of the throttle plate shaft aided and abetted by the tension of the return spring, the bushing areas wear and get ever so larger. As the bushing areas get larger they allow play to develop but more importantly they allow excessive amounts of uncontrolled air into the carb. And this will royally mess up the functioning of the carb by creating an overly lean fuel mixture. It will also make it all but *impossible* to correctly adjust the carb. Before you go off spending time and effort trying to get this engine to run right, you need to evaluate the throttle plate bushings. You can remove the carb or do this with it mounted on the engine. Remove the throttle linkage and any return springs. If there is a choke coil (spring) disconnect it's linkage. You want nothing to put tension on the throttle. Usually the throttle cable connects to some type of arm connected directly to the throttle plate. While holding the arm try to move it back and forth and in and out ...if there is any discernable movement then you have worn bushings. A new or properly rebushed carb will have no discernable movement or just the absolute *slightest* when you do this.

If the bushings are worn then you either purchase a rebuilt carb with new bushings or, better, have the original carb "re-bushed" by a carb shop specializing in this procedure. What's normally done is the carb is disassembled, the bushing areas are re-drilled larger and bronze bushings are pressed in. Cost of this service varies and it may include checking the mounting flange for trueness and/or a rebuild.

Unless you have some desire to keep this 310 as original as possible and given the cost of a rebuilt/re-bushed carb, I would take the rebuilt route.

Runs slow

In California the new blowers have sealed mixture adjustments and you need the have your carb. mixture adjusted be a qualified shop. If your carb. HAS mixture adj., turn the high speed mixture so it runs best at high speed, then turn another 1/8 turn counter clockwise to be a little rich. Then at idle adj. the other screw till it idles best.

Honda snowblower, starts well, and runs smoothly on idle, however on max throttle it cuts out; the choke part of the throttle seems to work fine too. Any idea what the problem is?

give it a little throttle, just before it cuts out. and adjust the carb, screws for best performance. if it will not run good after the adjustment. then the carb needs rebuilt, it may have dirt in it! good-day !

When you give the motorcycle a littlethrottle it wants to shut off. If you give it throttle fast she will go. Carbs were just rebuilt

what bike? what year? without anymore information, i would start by checking the fuel screw at the bottom of the carb....if this is a yz you'll want to close the screw all the and then back the screw out 2 full turns, or it could be the excel pump....when you took the carb apart, you didnt loosen the ssrew that holds the TPS on the side of the carb did you.....because then you have a throttle position sencor problem. but, i need more info...what was done, or changed when you rebuilt the sure it is something minor

How to tune the carburator on a 87 chevy caprice brougham?

An 87 Caprice shouldn't have a carb from the factory. As far as I know it should have a throttle body injection system. But if it does have a carb the idle screws are sealed with caps that have to be removed before they can be adjusted.They were preset at the factory and the carb would have to come off and be rebuilt. The best thing to do would be to find a good shop that can do it or buy one rebuilt at the autoparts store. Then you only have to set the curb idle, which is a spring loaded screw the bumps against the throttle linkage. Hope this helps.

I have a 1982 Pontiac Trans Am, everything is basically stock on the car besides my K&N filter, magnaflow exhaust, and edelbrock valve covers. It is equipped with a 4 barrel carb. My problem is that...

That carburator most likely has vacuum secondaries, meaning that the secondaries won't open until there is enough vacuum for them to operate, usually mid or full throttle. You can try to operate them by hand to confirm that the shaft isn't stuck.
