Question about 1982 Honda VT 250 F

1984 CT110 won't idle consistently

I have just rebuilt the top end on my CT110. I cannot get the idle to run at a consistent low speed without dying. If I put the choke on slightly it runs smoother but at a higher speed. I then must lower the idle speed. As soon as I rev the throttle the choke returns to full open and the engine will not idle for long without dying. I sense it is running too lean. I have more fully opened the pilot needle but seems to have no effect on engine rpms or enrichening the mixture. There is a slight stumble upon quick acceleration. I have checked the filters and find no restrictions. The float is allowing full filling of the bowl.

On most bikes, opening the pilot needle screw actually leans the mixture , as it is an air screw, not a fuel screw. I'm not for sure that this is the case in your bike, but if you can find out exactly what carb it has, I can tell you. Also, a freshly rebuilt engine is going to idle erraticaly until the rings are seated and broken in. Be sure to check your carb boots and vaccum lines for cracks and leaks, as a vaccum leak can cause a lean condition.

Idles with 1/2 choke. If open choke, or throttle - engine dies without any RPM spike. Carb was cleaned, jet is clean. When idles, there is gas in the primer bulb.


Hi, Andrew and the usual suspects are:

1. Fuel cap or fuel tank is not venting properly.

2. Fuel filter clogged.

3. Fuel line pinched or kinked.

4. Float needle and seat sticking.

5. Float level too low.

6. Carburetor bowl vent line clogged/blocked/pinched.

7. Idle adjusting screw set too low.

8. Air/fuel mixture screw set too lean.

9. Idle port, transfer ports, slow air jet clogged.

10. Slow fuel jet clogged.

Hi Kyle:
If it will run at high rpm and as you slowly decrease throttle it suddenly dies, there is a possibility that the low speed jut in the carb is either plugged or needs adjusting. Also , check the timing. If too far advanced, idle will not be good.

JUST REPLACED CARB ON MY 1992 CHEVY SILVERADO WITH A 4.3 LITER. NOW IT STARTS AND RUNS FINE UNTIL IT WARMS UP THEN DIES AND WONT START FOR 30 MIN


How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

get it running on idle,adjust the idle down till it runs hairy,then adjust low speed mixture screw till you get it highest revs,then keep repeating that till you get it idling normal.rev saw up max revs,adjust high speed jet, in or out till you get max revs,then screw out one quater of a turn.That lets enough fuel thru to cool the sparkplug tip..If thats no good,redo the carbi.Check the tiny filter under the needlevalve hole.Check the needlevalve diaphragm height.recheck gaskets are right way round

CAR RUNS GREAT, STARTED DIEING WHEN A/C WAS TURNED ON, NOW A FEW DAYS LATER IT DIES EVEN WITHOUT A/C ON, RUNS BUT WILL NOT IDLE


CHECK IDLE SPEED SHOULD BE 650 - 850 RPM. IF IDLE TOO LOW AC WILL PUT DRAG SLOW DOWN ENGINE CAUSING ENGINE TO STALL IF IDLE SPEED IS TOO LOW.

Chainsaw runs out of gas.


From your description, it sounds like your carb is running too lean. Make sure the spark arrestor screen is free of carbon build-up and the air filter is in place. Warm the saw up. With the saw at idle, adjust the Low adjustment screw to slightly enrich the mixture. If you turn it to run the fastest possible when idling, it is too lean. When the Low setting is right, you will be able to increase the RPM without it dying. If the High setting is way too lean, it may also die when you open up the throttle. If you run the saw too lean, it willl overheat and sieze.
