Just finished rebuilding and cleaning my carbs as per others suggestions on this forum. Found one of the needles stuck which I thought was my problem. Cleaned all the jets and everything in the carbs and put them back on the sled. The sled started up and ran good; no more gas pissing out of the carbs or overflows. The issue I am having now is that the engine does not run crisp up to RPM when you hit it. What could be the problem now. I have not run the sled at all this year; so, should I just be patient or should I look at syncing the carbs?
 
you are sure you got all the little side holes in the jets and passages? if you are then i would say yes to the carb synch.
 
Could be some dirt still there. Be sure the choke passages and needle are all clean, replaced if worn, and installed correctly. Check the slide upper chamber seals are all correct. I've seen more and more incidents similar to mine, carbs pouring gas into the air box and cylinders. I reommend all O rings replaced at 5 years. My carb gas leak and flood to cylinders, was due to the float valve seat assembly O ring. Be sure to look passed your slides to the butterfly, and check for any gas pooling. Gas will leak passed the piston into the crank, contaminate your oil. Before I found my problem I changed the oil 5 times, and got good at yanking the gas lines off the pumps quickly. I'm pretty sure at idle, the butterfly's are fully closed, and gas/air is through the bypass. The point is if you have this flooding, gas will pool at the butterfly, you may get an idle, but when you tap the throttle you are dropping that gas into the cylinder, and will hesitate struggle.

If you may have had ethanol gas in the sled, it could have left algae everywhere. I found green residue everywhere. My problem over one summer, at the time the fuel stabil for ethanol was just coming out. The only way I could recover the carbs, was to servicte it, sonic cleaning, full tear down. I put startron stabilizer in everything that sits for more than a month, for insurance.

Good luck with the trouble shooting.
