I pulled mine and cleaned it a bit, replaced the intake tube but now it is running somewhat worse than before. I can now get it to idle without the choke on but it is very rough and the floats are not stopping fuel from entering the bowl so I found a large gas spot under the machine after a short break.

I'll get it off again today and will pull the jets and float to clean them and hope that it will be fixed once I get it back together.
I need to figure out what if any settings I need to change. I noticed that if I have it running with the choke open at a higher REV, the exhaust pipe starts to glow red hot and I can only imagine that is way to hot for this engine and not good on the piston or rings.

It has been left alone for a couple of months at a time without being run, but was always stored with a fuel aditive in the tank and run through the carb. Anyway, it recently developed a new problem. It started popping and stalled. Discovered the rubber intake tube (between the carb and the cast aluminum intake on the cylinder head) has become loose and there is a gap which allows air into the intake without going through the carb. There is only one clamp at the carb-to-rubber tube side and none at the rubber tube-to-intake side (where it came apart). The blow-up parts diagram from the dealership shows the same thing, so how is the rubber tube supposed to stay attached tightly at both ends with only one hose clamp at one end? They want me to buy a $40 replacement intake assembly that still has just one clamp at one end. The other end seems to just be relying merely on pressure againstthe carb to keep the flanged end of the rubber tube tight to the aluminum intake tube. The design doesn't seem to lend itself to the installation of any kind of clamp I know of. If you have a 250 Bear Tracker (around 2001), please look at yours and let me know if There is a clamp at both ends of the rubber tube between the carb and aluminum intake, or is there only one - like mine.
Thanks.
