I need some good ideas hear please.
I have a 04.5 sp600 and have got some trouble. It starts fine when the machine is cold but only for a few minutes. You can drive it for about a block normal but then just bogs out then you must pull choke fully out to restart it and leave it to even move. Once it warms up it will idle but the second you give it some throttle while sitting or driving it just cuts out and dies and you can't start it again unless you pull the choke fully out and give it lots of throttle. Then you have to leave the choke out to keep it running the second you push it back in it just dies again like its starving for fuel. Replaced plug and cleaned air filter but did not make a difference. Not sure where to go from here. I was thinking the carb??
Any suggestions??

 

Sounds like it time to take the carb apart and clean it.

 

you may have got some dirt in the carb. maybe the needle,jets or passages plugged. yourvent lines are all clear and not climped as well. not sure does it have a fuel filter onit is it full of crap? just a few suggestions.

 

It sounds like you got junk in the carb. But also check to make sure the clamps to your intake and air box are tight. Also make sure the airbox is sealed. Its probably not an air leak, but make sure. Too much air will make one run like crap.

 

Also check your intake boot where the carb goes in they are bad to crack there.

 

Air box is sealed as normal.
Intake boot looks good.
Took carb apart last night and cleaned the parts and took out jets a sprayed them good. Put back together seemed to run good for about 1 mile and then same thing again just died out and once started again had to leave choke out again to get home about 1 block. Drained all the fuel this morning and put in new gas. Still have same result. About a month ago I also noticed some antifreeze being used with no leak. It went away but appears to be using more again without a leak???????
Could it be a head gasket?
Cracked head?
Any ideas anyone?

 

Blue I know you checked the boot between the carb and the head but did you look real close and push and twist on it.I had one go bad on my sp700 and put the carb on and off three times befor i seen the small split in the rubber boot.And mine was acketing just like what your talking about.And like these other guys were saying sure sounds like something with the carb to me.

 

Yea you really got to look for the crack in the boot.

 

You guys Rock!!!
sure as heck took the carb off again today and inspected the intake boot again sure enough found a crack on the top. Will get one ordered.

Thanks for all the help...
