Ok this is the third post on this particular machine. Still cant get it to take fuel. It will Idle fine, but has no take off power, meaning when I stomp on it it hesitates, kinda like double tapping the throttle on a dirt bike, and pops through the air box. I just rebuilt the carb all new jets, o rings, everything except a new diaphram and slide. adjusted the float to the proper height, followed the steps from the service manual. And it still pops and wont take fuel when I stomp on the gas. I am at a loss, and highly aggravated, LOL.


I noticed, and this has been going on for at least 2-3 years, that when we start it, it makes a noise, (which I always thought, and the owner confirmed) that sounded like the starter slow to disengage, kinda like the gear slapping on the flywheel, It only makes this noise for about 2 seconds upon starting, and doesnt matter if its hot or cold, although cold seems to last a second longer. Always thought it was the starter, owner always thought it was the starter, cause that is the general posistion that the noise originates....... However, we have always started it from the drivers side. this evening after installing the newly rebuilt carb, and trying to adjust the throttle and choke cables, I hit the starter and low and behold I believe the noise is coming from the timing chain. when It starts it goes tick tick tick tick, and it is higher up on the motor than the starter. Hmmmmmm?????

To go back a bit as to what started this whole problem, was the owner stated that one morning he went out and started it and heard a pop noise, and then the problem arose with it not taking fuel.

could something have broken in the timing, but still allow it to run??? Ive never work on these before and know nothing as far as how the internals function, ( Im a Honda Man).

Ive done a ton of work to this thing, New u joints, drive belt, rebuilt carb, oil change, spark plug, fuel filter, checked the pump replaced fuel lines, and brethers, Im just about to push it over a cliff.

It runs good in every feature except when I goto take off fast, then it sputters. ARGGGGGGG!. Need some advice please!!!!!!. Thanks

Does it start to run somewhat decent after on the throttle for a second or does it keep popping.

 

[kevin8509]

When u say you checked the fuel pump do you mean a visual inspection or do you mean you checked pressure?

 

[bmdakk]

It hesitates and keeps popping through the breather tube that runs along side the airbox.as long as I gradually get on the fuel it seems to do ok, its just the initial stomp when it bogs. If I can figure how to post a video I do that, Im not real good at decribing noises. and I ohm tested the pump and visually watched it pump, didnt do a pressure test. The ticking stops after 2-4 seconds

 

[kevin8509]

Hmmm. Sounds like it could possibly be getting to much fuel and its taking a second to burn out the initial burst of it possibly... Also maybe just kinda talking out loud but what's the choke situation on it??? Is it possible the choke is sticking open on it a little bit to over fuel it...

 

[bmdakk]

could be, Ive tried locating where to screw the cables in as an initial set but have had no luck. I put them back as close as I remember when I took them off the first time, but it seems to be doing the same thing. Im gonna recheck the float height tomorrow, But I triple checked that before I put it all back together. Like I said Im at a loss. Ive never had this much trouble with atv carbs on Hondas, and Ive rebuilt dozens of them. Just dont know what to think. I hate to keep guessing and throwing the owners money at at it. Cant buy a carb kit for this particular ranger, we had to buy each jet and oring seperate. just dropped $187.00 on rebuilding the carb, to no avail.

if it pops in the airbox its a Lean condition, and what you describe stomping on the gas and not going same thing. pull your diaphram out and use a light to ck for pin-holes lightly stretch it. But Odds are it has a partially plugged passage in the carb or the pump is bad.if possible soak over nite in water with a little vineager you dont need much it works good cleaning out what you cant get to. and if you can heat the solution it works even better use a crock pot, or get a ultrasonic jewlery cleaner works fantastic. And get on ebay buy a new pump get a generic one they work great. $187 for a re-build Yikes i just did mine for $30 and i re-jetted . set your idle screw 1 1/2 turns out max of 2 turns set your float set it high if you want the only result would be fuel runs out when its sitting at least it wouldnt be too low. you can always re-adjust it

Also make sure pump is good before you try this or the results wont be the same do this get it running warm up the engine pull your choke out a little if it gets better and runs good its lean, revs and dies choke working good. Set your cable hook it up turn adjuster until it just starts to move the plate back off a hair,its now set tighten lock screw. remember the basics first you have to have fuel buy a pump first.

Thanks Bruce, I soaked it in Room Temp Lemon juice for almost a week while I was waiting on parts for the carb to come in. Ive done this numerous times before on Honda carbs, The citric acid does wonders. I start out with a big pot of Lemon juice and get it boiling and then take it off the fire and put the carb in. Usually overnight soaking does the trick. Ill keep the jewelry cleaner in mind for future reference. I will check on the pump, I wish I could have found a kit for $30. I talked to 4 different dealerships and parts guys and all of them told me they dont make a kit for the 99 ranger. I found ones for different years for a whole lot cheaper, however the jets and stuff were gonna be different, and was told it wouldnt work. The float valve alone was $55. I about fell out of the seat when they told me that.

have you looked really close at the slide and needle and diaphragm? I'm sure you know this, but the throttle cable opens the butterfly, but all that does it allow more air to start to come through. the slide is solely responsible for the accelerating. I had a bayou one time, wouldn't accelerate and running weird, finnally tracked it down to the slide needle loose some bozo lost the retainer when they had it apart. maybe remove the air cleaner hose, and watch the slide when you open the throttle? I would thoroughly check the slide needle and diaphragm. maybe that pop did something to the diaphragm. also verify charging voltage. I have seen several cases on other machines, rectifier was producing high voltage, and the machine wouldn't accelerate and run much over idle. charge volt should be like 14.

later!! Chris

Thanks Ill look into that. I replaced the needle but not the slide or diaphram.
