I have a 1991 500 polaris indy Sp and i can't figure out what is wrong with it. It will bog really bad so bad that i would have to push it along then if you can get the rpms up it will work fine. I took it into my shop and changed the fuel pump cause i took the bung out on the front of the engine and quite a bit of gas came out both side i took the vacume hose that goeas to the fuel pump off then pulled it over and it sprayed gas out. Today i took it for a test drive same thing happened so i took off the air breather and there was all gas on the bottom. For some reason it is flooding itself some how. Im going to change the jets from the stock 280s to 270s mabee that will make a difference. And i also took both chokes out and sealed them by putting the plunger thing in with a spacer then putting a bolt in it and i put a primer on. if anyone has any idea of what clould be wrong please tell me.
