Anyone know of one for a 280cc engine?

 

Don,t all carbs climb hills good? Both my ATVs are carb and they will run all day standing on end. I have tried it.

 

I just got a 300 king quad, put a 26mm 230 quadsport carb on and when I get on a hill not quite as steep as your tree in that pic lol, but close, the carb runs out of gas and the engine dies. Its not instant, but while trying to claw up the hill.

I was reading around and some carbs do better than others, but the true solution is propane they say. I don't need to get that radical.

Since I need to buy a carb anyway, I want opinions for a good hill climbing carb. Just figured I'd ask and see what people say.

 

could you adjust the float so the bowl is filled up more before it goes out the overflow?

 

I spent the entire day fiddling with the floats, pilot, air jet, needle jet, and tried about 5 or 6 different needles. For a while I had it pretty close, but it wasn't perfect. Since then its gone downhill and I gave up for the day. I think the 230 carb just isn't made for this kinda thing. Get your 230 at a steep angle and see if it will idle.

I might try the TM28 or VM32 next. I hate to take a carb off my quadsport that took me forever to get dialed in and start from scratch on a 4x4. Then again, I kinda think a 32 is too big for a 280cc engine. I have a 24mm bayou carb I could try, but that has to be too small. Wish there was some way to get fuel injection.

 

You could try an oko or pwk 30mm carb. That was the carb im planning on getting for my lt250s engine. OKO 30mm Racing Carb Flat Slide Carburettor | eBay

Many people use these carbs on blasters and banshees and they are good for two and four strokes. Just might be the perfect size if 32 is too big and 28 is too small. Plus, its decently priced.

 

That is a good price! It looks similar to my 32mm, but mine is a roundslide is all. Looks like same bowl anyway.




I put the 32 on and will see how it does tomorrow. I'm curious about the big bowl size on the hills.

I've never been able to get the 32mm to work on anything. I've tried on a 300 Lakota and 250s. And I tried a 38mm one on a warrior. Its always the same trouble. I can get it running perfectly all thru the throttle band (after hours and hours of changing needle jets, jet needles, air jets and fuel jets... pouring over charts and fiddling with a micrometer), but if you jab the gas to wheelie, it stalls. I think carbs this big need and accelerator pump... or a much bigger engine that sucks more volume thru the carb. I have just about every needle sudco sells and a box full of jets. Plus I have driull bits up to #100. If I can't get it running right, I can't imagine who can and if someone did, then any little change afterwards would throw it off severely. It would be termpmental at best. But I'll see how it goes tomorrow.

 

I ain't believing this.... I took a shell of a 32mm carb and threw in a O-6 or O-8 needle jet (can't read it for sure), a 250 main, a 25 pilot, a 2.0 slide, and 5L1 needle on 3rd clip and it ran darn near perfect first try! My lucky day... I should buy a lotto ticket lol. It runs perfect. No stumbles anywhere. All angles. I guess the big float cavity made a difference... along with a pretty restrictive small foam filter. I think these carbs need that restriction behind them to work right. I'll post pics later.

 

Here is the carb that worked.
