Hey guys, in order to replace the intake manifold (oem part) do you have to take the carburetor off or will it come off by just loosening the clamp at the carb and removing the 2 screws connecting it to the cylinder on the other end?

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.
rubber piece between carb is sealed to intake flange ,if its cracked it must be replaced, no sealant that I have tried will seal it, they are about 50 bucks.
only one clamp

Yep....gotta be repaired correctly or it wont work, shortcuts usually cost a lot more in the long run! Close fuel shutoff and run carb dry if it is going to sit for months, better yet, take it for a spin once a week....

Default Carb Erving out

I have a 99 Yamaha big bear 350 that if you give it over 1/4 throttle it revs out and does not move. I put a new carb kit on it tonight and did not change a thing.
