Very carefully, all your parts need to be taken care of, the honda shop doesn't sell complete kits anymore, they sell the parts you need, only, so you need to know what you need. The jets have tiny o rings on them that only come with carb parts, so protect them, the jets need to be wired out with a guitar string, .009, you can get one from a music store from the garbage can, unless you play. Clean them out so that you can blow through them, make sure there is no rocks in there, no turpentine, no gunk, soak them in carb cleaner, then reassemble, There is no adj on them, they are fixed. If they don't work you need a different jet. I bought a kit from dynaflow, adj jet kit for my bike, the factory set jet didn't do diddly, but the dynaflow worked great, Hope this helps.

I have a 230 merc marine engine and when starting fuel is comming up through my carb causing boat not to start

remove the carby and clean out the rubber dirt under the float needle
marine outboards suffer a rubber degradation of all rubber parts and it blocks carby jets, needle and seat holes
IF you are interested in boating safety ,take it in to a merc service center and have the fuel system checked out properly

Engine is not starting very well. After much cranking and almost starting, it runs, just. If throttle is moved up or down it stalls. What else can I do ?

not enough detail as to make and model but if it is a carby engine then the main jets and idler jets are blocked
the rubber components from the tank to carby break down internally and small pieces of rubber get to the carby
water and corrosion are also other problems associated with this fault
all out boards exhaust out the prop and by running the engine in a drum , then the oil in the drum is the oil and smoke collected by the water in the drum
While this is an excellent way of running a motor , remember that the oil mixture is being recirculated through the water pump in the leg and that will cause problems if you run the engine then leave it unused for a period of time
The rubber of the pump impeller will crack and fail when again used
Take it to a service center and get a proper diagnosis done and a quote

How do I clean a carby

You can first try some carb cleaner. Remove the air cleaner from the carby, and the fuel inlet tube. Soak the innards or the carby in carb cleaner, and try to full the fuel bowl as well, via the inlet or the vent tube.

If the main jet and idle jet are gummed up the carby will need to be disassembled, at least partially. There are overhaul kits you can buy with new gaskets. Go very slowly as there are springs and little steel balls in a carby, and these have to be replaced correctly.

You can also get recon carbys for most models.

My 2 Yamaha ef2000is generators will only run anything in my camper that requires power (ac,tv, or microwave) unless the choke is on about a 1/4 of the way.

dirty carby jets. it is not receiving enough fuel thereby needing the choke. remove carby and clean jets thoroughly or simply try removing air filter & squirting carby cleaner into carby throat whilst revving engine several times, this sometimes works enough to solve problem.

Eninge wont start unless petrol is tipped down carby. carby is a rochester quadrajet with auto choke .

might have to put a carby kit through it, the jets might be blocked thats what it sounds like. when you poor it in the fuel and air gets in straight away but if the jets are blocked you wont get the fuel through. try carby cleaner, use the accelrator cable on the side of the carby to rev it right up while spraying in carby cleaner car will try die out then let off the accelerator. basically you have to clean your carby out

My 1991 suzuki gsf400 has erratic idling. also is hard to start.

This could be almost anything, probably minor. Good premium unleaded fuel, fresh/clean and gapped plugs, fuel filters clean,. Carbies clean and jets good, correct float levels, no air leaks in intakes, air filter clean, Electrical connections 100%, ignition coils OK, no sign of moisture behind magneto/stator cover or on source/pick-up coils. Engine earth wire secure from head to frame?
New plugs, 0.7mm gap to start with and set air* mixture screw 1.5 turns out.
To flush carby with cleaning solvent (spray can from auto access.) Take float bowls off (check for sediment) and fuel lines off and spray till it pours out of float needle seat, Loosen carby clamps and swivel carbies outwards 90 degrees and unscrew pilot jets and spray thru also. Check operation and smooth return of choke.
* Air mixture screw controls fuel-air mixture at idle speed and is a trial and error thing. Pilot and Main jets regulate cruising and acceleration mixtures and ranges according to rider style and riding and climate conditions.
If there is any undue noise comming from the top of the engine with revs slowly rising from idle to 2000 revs, you may need to check camchain tension and valve clearances, easy done with some simple tools and a manual. Downloadable free with an engine search!
Goodluck and Cheers.

My yamaha xt600e starts to to choke/stall like if iit lacks gasoline every time i pass 5k rpm in 2nd,3rd,4th or 5th gear. What could it be?

You may very likely have an issue with your carbies. The jets may be gumming up with sediment over time or secondary carby needle is worn or sticking. A carby cleaning execise may be a cure or a service at your bike dealer if your not mechanically minded. The carbies are a little more complicated than the normal single carby and have more jets and slides, as well as a delayed secondary carby linkage.

1989 toyota camry 232000miles Runs rough at idle

YOUR problem is the carby acc pump and idle jet ...... what you need to do is remove airfilter and take the top off the carby and you should see a small ball and spring under gasket ...when you open the throttle it will pump petrol to the small pick up jet and the other jet will take over ...clean out carby jets and rebuild and that should be ok

If its been sitting for a while or run through a lot of water or water in the fuel, try draining the carby 1st by lossening the 17mm drain plug at the bottom of the carby.
if its full of water and or gunk you should remove it and clean.

With patience you can remove the main and pilot jets to clean them..The Pilot sounds more like the problem.....If you have to get the carby off remove the rear (seat) frame lower bolts loosen the top bolt rear ex pipe and swing the frame up watch out for the wires then remove the carby...

Try removing the jets can be a pain but its much easier.

Stalls after 1minute of starting

sounds like you have a clogged pilot jet. did you remove the jet and make sure it is clean by holding it up to the light? could you see through it? you mentioned that you cleaned the carbs, but if you didn't remove the jets and make sure they are clean, then more than likely your pilot jets are clogged.
