Assuming your question is, "How do I set it up to idle properly?" Just rebuilding the carburetor isn't enough to get your bike to idle properly. If it idles high, there is either too much air or too much fuel going through the carbs. Were the jet needles replaced at a level appropriate to the air intake? If you also replaced the air intake, i.e., replaced the air box with pods, you will need to reset the jets at a different height. (More air needs needles set to let more fuel pass.) Hope that helps.

You have disturbed the settings of the fuel air mixture and so there is flooding in the cylinder. Now it is possible that the air screw and the idling screw was turned.
remove plug and pump out all the excess flooding by kick starter. Once all the fuelis dispelled turn the screw fully into and then unscrew about one and half times. This must be done for the air screw . The idling screw can be kept about one turn out.
Now start the engine and use the throttle screw to put the engine idle higher than idling speed. now turn the air screw to give a stable point --it will be around this settings.
once done correct the idling and set to correct ticking of the engine. make sure that the timing is correct, the plug gaps are set right.

SOURCE: I need carburetor help for a 1980 Honda CX500.

For parts the best place to look is David Silver Spares, if they don't have it then there is a good chance it isn't available. To synchronise the carbs you will a set of vacuum gauges. They aren't expensive and they come with instructions.

Engine missing in gear


Check your Air Filter, clean it out, check for obvious blockages. Change the filter if it looks well used (look for excessive dust or color change on the inner part of the filter) or obvious wear.
Check for other blockages around the air filter inlet.

Check the spark plug, just change it for a new one so that eliminates that possibly.

Check your fuel filter and replace if needed.
Check the fuel tank for corrosion or dirt in the fuel. Empty it out, Clean it and add new fuel, be sure you have the correct fuel.
Check your Air / Fuel mix adjustment screws on the carburetor.

Hope that helps a bit
Good Luck

13 horse Honda presure washer (landa) won't start. Been sitting for several years. Checked plug which looks new.. Maybe wrong one? Will sypone old gas and replace. What about plug, fuel filter and air...


you can try and remove the old gas the carburetor and perhaps the fuel filter are most likly fouled with gunk from the old gas. When gas sits, over time it forms a thick gummy deposit that can clog carburetors, and anything else. try fresh gas with some carburetor cleaner (NOT the kind in the spray can) mixed in. It may need to have the carburetor rebuilt or replaced.

98 honda magna. had fuel stabilizer last october. now it starts with choke but won't rev or idle. only choke keep it running. switched out fuel. put new fuel and additives, but nothing good yet. what...


Even though you put stabilizer in the fuel, it sounds like the jets in the carburetors gummed up. Additives wont do much good at this point. You need to remove, disassemble and clean the carburetor passages and jets.

Engine bogs down when speed is increased.


Ok I have r Royobi Tiller (30CC Gas) And last year it ran fine after rebuilding the Carb. This year it was "hard starts" Idles fine, (Tiny whisps of blue smoke in exhaust with correct ratio) Even seems to run better with the choke "on" but still...at idle only. as soon as I touch the throttle...its bogs down in tune with how much gas I give it. Little throttle? Little bog down, Little more throttle? Almost stalls, a normal throttle rev? it stalls dead! Then starts right back up again in 1 pull and idles fine again!? WTF? So after cleaning a clean carb again, (twice) and seeing no change I thought I'd go look at the original diaphragm and compare it with the rebuild kit diaphragm (which is the one in the carb.) And guess what? The replacement has a larger rivet by a factor of "2". So basically it was flooding the carb, I bent the needle tang down, better but no cigar. But I could rev it half way now. A second disassemble to bend it yet a bit further and Vrooom vroom vrooom ****! So check your needle valve even though you think its 100%. (Especially if you rebuilt the carb with a kit!)
