 07 4x2 kawa motor hard to start

when starting I have to use the choke and even then its a chore to get it going but once it goes the choke is not necessary. Its like the carb is not getting gas. stepping on the throttle while choking helps but u have to pump it lightly. have to use choke to start even when warmed up. Bad fuel pump? carb adjustment? motor doesn't seem to have much compression but runs great once started. need some clues before i get in over my head

How old is the gas in the fuel tank? Is the gas you put in the fuel tank ethanol formulated gas? If the answer to the above questions is the gas is pretty old and it IS ethanol formulated gas then I would recommend that you drain all of the gas out of the fuel tank and replace it with fresh from the pump NON-ethanol formulated/ethanol FREE gas.

I also recommend treating ANY gas you get (ethanol FREE) with Stabil using the double dose treatment. This will help to preserve the gas you have stored in cans. Ethanol gas will eventually separate into ethanol and gas. The ethanol will absorb water and allow bugs to grow in it. This can cause the symptoms you posted.

Hi Fishy,

While I was reading your post I was listening to one of our guys trying to start our spray mule--wrong day for spraying, but not my call. Any way it sounds like we have the same problem. (same engine) It sounds like a plugged idle circuit. If it's been sitting awhile, though ours hasn't, the corrosive (to aluminum carbs) ethanol/water mixture sitting in the float bowl can plug the idle jet. This is a little tiny passage. The different circuits in the carb all overlap to a certain extent. A clogged idle circuit will make the engine run leaner throughout it's operating range. I'd be willing to bet a good cleaning would solve the problem. Sometimes you can get lucky by removing mixture screws and float bowl drains and spraying carb cleaner into openings and blowing out with compressed air. Make sure you know how many turns out from full in the adjustable screws are before removing them. Note springs and such. Otherwise I'd pull the carb and do a proper cleaning-though noting settings still applies. I'll let you know what I find with ours.

Hi, I have a brand new 11 hour old th 6x4 gator and it is the same way, according to Deere it is the fuel injection/carb that is screwing these new ones up. I have 6 others all older and this new one is by far the worst to start, Just as you have stated, choke out grind grind grind, pump gas, starts after what seems like a long time, then the choke has to stay out for a while before you can even think about moving the machine. Kind of disappointing considering this is a brand new machine.

fishy1, See my post below, "CX Choke Revisited". You have a idle circuit problem. The holes/passages are tiny, take the carb apart and soak it overnight.
