SOS MAJOR Fuel leak Polaris Xpress 300 1999

Your cover has been updated to a harder cover part #5433542. They're expensive but you can check for good used ones. If you go to the larger bulbous later model covers,you would have to make adaptions for the smaller exhaust dust you have on the 300. Easier to just stay with the updated one for your model.5433542 Polaris eBay

The main reason the clutch covers made noise,sliced covers from belts,etc was that they were too close to the outline of the clutches,air couldn't circulate as well and were made of soft plastic that could get hot and warp. I've seen all sorts of melted covers. The updated covers allowed a tad more room and were made a lot stronger and this generally took care of the problem. The latest bulbous covers allowed more room and air circulation plus air inlets and ducts were larger and they had drains.Some used these and modified air their ducts to fit. As far as fuel pumps just get a cheap one on ebay for less than 12 bucks..http://www.ebay.com/itm/Fuel-Pump-Fo...xYXe4W&vxp=mtr

Also, the carbohydrolyzer-doohickey kit is here. No, not a typo, it is my new nickname for the carb, because it has comedy value and a backstory based on a friend getting drunk to the point of retardation. Anyway, back to the point at hand, which I shall go about bringing up in the bluntest manner possible; Wat do? In terms of adjusting and checking I don't screw it up. I get how to switch all the stuff out, change idle speed back to where it needs to be, and simple things, but once it gets more complex than turning a screw carefully, I tend to mess up adjustments.

How you really adjust the pilot screw is to have the engine warm,pilot screw at base setting,engine at at a steady idle around 1000 rpms or so,doesn't have to be dead on. Idle adjuster low enough to where it shifts without grinding gears when shifting. Turn the pilot screw out slowly until the engine begins to bog then back in until the idle is smooth and throttle action is smooth. OR as some do,out on the pilot screw until the engine starts to bog,then back in(counting turns)until the engine runs rough again and then set the pilot between these two points. Usually close to the setting on what the blamed manual calls for in the first place in a lot of cases..

Pilot jet that sets right behind the main jet. Sets deep. Use a good screw driver to get it out so you don't mess up the slotted head. Look at this section from the manual on cv carbs. You have the VM30 carb.https://www.google.com/url?sa=t&rct=...U2gGlaHJWSIlbA Plus here's a couple videos on your carb that can help.https://www.youtube.com/watch?v=AOJlHIUUBk0 https://www.youtube.com/watch?v=wfVQUBO7LjQ

Glad you have it running.. Actually on this two stroke carb,this screw is called the air screw and located at the rear of the carb.It cuts down or allows more air to enter the carb to mix with the fuel.Usually sets between 1 1/2-2 turns out depending on condition of engine.On a 4 stroke,the pilot screw is closer to the front of the carb and controls fuel flow into the cab at an idle. I'm guilty of calling them one or another myself..
