2007 honda 400AT carb problem won't start DEaler said they have had problems with sticky floats and seats but now they so they just cann't fix it !!!! any help Please

 

Is there fuel getting to the float bowl? IE if you open the carb drain with the petcock on do you get a good stream of gas out the drain tube?

If not, probably need to pull the carb and clean it.

Some of the 10% eth fuel is actually higher, and ethanol seems to cause problems in smaller engines.

Here, at least, some stations have ethanol free fuel in premium.

 

Yes getting fuel The valve keeps sticking in the seat .I use stabil in my fuel. My dealer says alot of 400At have this problem (4times) now for me. And they just can't fix it. I'm thinking new carb maybe

 

Friend has a Honda Recon that his oldest son bought way back when. He beat the tar out of it and handed it down to my oldest son's best friend. He beat the tar out of it. My son learned to ride on it. A few of their mutual friends learned to ride on it. They beat the tar out of it. Now the youngest son has it and routinely beats on it. Even though it's needed a few repairs, it's still ticking pretty well. My ideal quad would be the power of a CanAm, the reliability of a Honda, the ride comfort and strong frame of the Polaris, looks of a Brute Force, and the utility of the Sportsman X2. I don't have any problems with my X2 after 2,000 miles but all of the above would be a nice mix in my mind.

 

Using too much stabil can actually gum things up.

So is the float sticking open and overflowing the carb, or is it sticking closed and not getting fuel?

In any event, I'd still take it apart myself and see what's going on. Blow everything out with some B-12 Chemtool, and if everything looks good and the float and valve seem to move as they should, put it back together and see how it goes...

 

I really wanted to buy into the Honda reliability thing and went a ahead and bought two of them - a Rubicon and a Rancher. Then, as another son reached riding age a Recon joined the fleet.

I use freash gas, StaBil, aviation fuel, young virgins and special dances with praprika but have thus far replaced the entire carburetor on the Rubicon ($200+ and my own labor), rebuilt the carb on the Rancher (after a couple tear aparts and cleanings) and suffer with a Recon that won't idle properly unless it's hot - as in the engine is hot AND the ambient air is hot, a rancher whose flooat overflow wants to leak ona nd off and a Rubicon that will be totalled if the trans ever quits!!&^%&*^$%

All the while, we are also dealing with Hondas that need LOTS of hand-holding and cuddling in cold weather. While the other guys at deer camp are having coffee and getting their gear settled while letting their quads idle/warm-up, we are baby-sitting the darned Hondas holding the choke and manning the throttle.&^!%&(^!%

Then, I buy a Grizzly 700 fi and learned what pushing a button and going back in for coffee is all about.

Don't get me wrong, the Hondas are OK but when you look at the initial purchase price compared to others and the cost of a replacement transmission on the Rubicon should it ever need one I have to ask myself, with 75% of the fleet saying "Honda" did I really do the right thing??

 

That's pretty strange. I'd be wondering if there is still trash in a passageway in the carb and/or if the enricher is working properly.

My Foreman with the same carb is a simple start, whether it is hot or way below freezing, and I've never had to clean the carb or otherwise work on it.

When you say you have to hold the choke, is the **** not staying out or something?

 

Im 53 yrs old , have been riding dirt bikes, 3 and 4 wheelers since I was 10.

I've also owned ever major brand ATV on the planet, bar none. My last Honda's were brand new 2003 650cc Rincon and 250cc Recon. They were ''OK'' ATV's, but like somebody already stated in an earlier post, Honda's are cold blooded.

I drove the Rincon for 2 years and become utterly disappointed with the lack of a low range,no down hill engine braking, no adjustable shocks, no locker mode for the 4x4,none adjustable shocks,leaky drum style rear brakes, and poor ground clearance. My Honda's were no more reliable than any other brand ATV's I've had in the past, EXCEPT for the two POS Polaris ATVs I had back in 1999 and 2000.

I sold my Rincon and bought my first EFI ATV. It was a 700cc Suzuki King Quad with EFI and it did most everything better than my Rincon, would blow the door off the Rincon in a drag race, and cost less money.

My wife decided that she wanted to start riding with me instead of riding her own ATV so I bought a new 2006 Can Am 800cc EFI Max, still own it today.

Honda does not have as many of the features that the other brand ATVs have and cost more $$ to buy. I wont be going back to Honda until they address these issues.

Honda reliable?

SURE, but so are all the other major brand manufactures ATVs made today.

 

I have 19 honda atv's 14 300's from 88 -2000 2x4's and 4x4's, 3 recons and 2 rubicons ,always rode the Honda since i was about 8 years old( now 50 + !),from QA 50 to the SL70 SL 100 XL175 to the first of the 3 wheelers from the atc 70 to the big red 250 then the 86 350 D 4x4 (the tank)and now i have been collecting every old honda atv i can find,within 200 miles. There were only 3 i could not get running and one had a bent valve one with a worn out timing chain and piston/cylinder,and a recon that i think has severly worn chain or has jumped the chain by one link(strange symptoms still trying to diagnose),i'm from south west fla and have ridden these things all over Fla,Ga,and Ala terrain, We and my buddy's did a trip to Tenn a couple years back(Coal Creek)to go up into the mountains and hills ,4 units went and only one still ran after a week of there most extreme coarse they had ,the Honda rubicon was the lone survivor, 2 Yamaha rhino's with burnt out clutch's and one Suzuki eiger with a shreaded drive belt,I'll admit it was everything any atv or utv could do to make the coarse but my Honda passed with flying colors,the low range Hondamatic and the 27" vamps got me through all the heavy deep gumbo mountain top slop but still had the power to climb super steep inclines with slick tire clogging clay even dragging back the Eiger,what a great place to ride,alot different than flat Florida. We will make it back there when it cools down some, Go Honda !

 

Like I always say get an honda if you wanna keep it.. get whatever you want if you get a new one ever 2 3 years.
