"I just bought a 2001 2hp Envirude. The first time I took it out the motor would run for a minute and then rev up for second and then shut down. It would be ten minutes before the motor would start again. I noticed that the drain holes were not dispersing water, so I assume that the problem is the impeller. Is this correct? Why does the ngien rev up before it dies out.

Thanks.

"Sounds like a fuel flow problem.

Check the tank vent is open OK (try it with the cap off)

Check the filter incorporated in the fuel shut off tap.

Check the tap is opening properly.

Make sure you are getting a good fuel flow to the carb.

The cooling system has a tell tale. If you do not get a good stream of water from that when the engine is running start by checking it for blockages. Outlet nozzle, hose and connection to the engine.

If that's all clear then the water pump is very accessible. Take off the prop and the water pump cover plate then exposed and there it is!

Exploded diagrams on the BRP parts website will be very useful."

"Revs up before it dies out as the fuel mixture gets very lean just before it runs out completely.

You may have two problems here, one faulty impellor and a fuel issue. Check the impellor first.

It sounds like you also have a blockage in either the vent or the tap."

(Carburetor Adjustments - Two Adjustable N/Vs)
(J. Reeves)

Initial settings are: Bottom high speed = seat gently, then open 1 turn out. Top slow speed = seat gently, then open 1-1/2 turns.

Setting the high and low needle valves properly:

NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle valve adjustment.

(High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to full throttle. In segments of 1/8 turn, waiting for the engine to respond between turns, start turning in the bottom high speed needle valve. You'll reach a point whereas the engine will either start to die out or spit back (sounds like a mild backfire). At that point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest setting.

(Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back. Again, at that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.

When you have finished the above adjustments, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.
