Question about 1997 Honda CB 750 Nighthawk

1 Answer

The choke when activated on the lever will not return fully on the four carbs(as they are connected by a long linkage).the choke parts on each carb will only go back part of the way,so she runs fast

I have tried gt85 and plenty of movement(i think)to try and get them working as they should but no change. i am able to push the connecting piece down and they return to where they should(with a bit of a click) any ideas? thanks. 1997

SOURCE: Strange thigs about YAMAHA TW 125

Hi
I have been working on my carb today,the pipe from the bottom of the carb should just run down by the bottom of the swinging arm,there should be another pipe from the pipe on the left side of the carb just above the fuel intake which also runs down to the swinging arm and connect to nothing.
Cheers

SOURCE: Won't idle without choke

The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.

A “very helpful” rating for this answer? Thanks!

SOURCE: rebuilt all four carbs cleaned and replace needle

With Mikuni carbs, the idle circuits affect engine performance up to 3000 rpm under light loads. If the idle circuits are restricted (by fuel gum, rust dust from the tank or dirty fuel, the results will be 1) the engine will run with "choke" on. 2) poor or no throttle response below 3000rpm,3) back firing and missing on the effected cylinder(s). Cure is to blow out the idle circuits and idle screw adjustment jets with several applications of carb cleaner and compressed air. Failing that, strip the carbs.

Installing a carb on a 1991 3 HP johnson. Does the choke insert in the linkage round hole or the oblong hole?


Hey Rocky, I would start with the round hole... This is a manual choke engine/carb..(butterfly in the mouth of the carb)... make sure it opens fully and closes fully when you turn the choke knob ....it needs to operate smoothly and correctly..if it doesn't swap holes..

Why four barrels do not open 65 4100 carb


The choke linkage is not properly hooked up or adjusted. The throttle linkage is not adjusted properly or there isn't enough vacuum. The choke linkage has a tab that prevents the 4 barrels from opening when the choke is engaged. There is a tab on the throttle linkage from the front 2 barrels that will engage the secondaries when they rotate past a certain point. Vacuum opens the top plates on the secondaries.

There should be no knack to it, fill with fresh fuel, move the throttle lever fully forward to choke mark if there, if there is a primer bulb down at the carb pump this three or four times, pull the bail arm at the handle bar fully in with your left hand and crank the engine with your right.

Triumph daytona 1200 95 running to rich loads of black smoke


hi,first place i would look is the choke circuit of the carburettors,if the bike has a cable fitted to the choke make sure that the cable operates freely,and returning fully to the off position,also check that the lever that the choke operates (on the carb)is returning to the fully off position,failing that,you may have to remove the carbs from the bike and check that the plunger(which is operated by the choke cable)inside the body the carb has not jammed inside its casing,failing that,you may have to have the carbs serviced by someone with a syncronizer to optimize the fuel air ratio,sometimes the mixture screws in some bikes have been known to alter with the vibration etc of normal operation,i would say that it is definatley a carb/choke/mixture problem that will not be to expensive to put right..hope this helps...cheers ian

Thottle will no stay in one position. There is a black spacer that slides over the throttle shaft between the shaft an the leaver. Will a new leaver come with that black spacer. Blower model wt200


Three (3) possible carbs were available on your machine.
If you have:
Walbro model WT-606 carb, the choke and throttle levers are available in kit form (which leads me to believe the spacer comes with them). Throttle lever kit part #530071726 and choke lever kit part #530071725.

If you have:
ZAMA model C1Q-W11 carb, the choke AND throttle levers are BOTH a part of the carb itself. (Would need a whole carb to get your part.) Complete carb part #530071465.

If you have:
ZAMA model C1Q-W11C carb, the choke and throttle levers are available in kit form (which leads me to believe the spacer comes with them). Throttle lever kit part #530071715 and choke lever kit part #530071716.

Hope this helps.

The easiest thing for you to do is look at another mower that has a single cylinder Briggs at how the linkage is set up. They will all be the same linkage from 12 hp- 20 hp.
