Thanks for the reply. Why wouldn't they make it threaded? Or at least valved somehow for controlled draining.
Its so rare that it needs to be drained, i guess they figured "this will do". The plastic is too thin to thread, if you were to over tighten it, you would need to pull the engine to replace the fuel tank. The plug holds pretty well, its just a pain in the butt to remove. You will notice the plug for the chain case is diagionally opposite to it. Make sure you remove the correct one.
That makes sense. I have identified the correct plug. Thanks for your help.

Make sure you put in a new grommet.
Ok I drained the fuel tank flushed it several times till it was clean fuel coming out replaced filter and squeezed ball with bottom drain on seperator open until fuel ran clean. It started and I used it for about fifteen minutes and it ran fine. Then last night I went to move snow and it started right up and ran fine but the exhaust smelled bad like unburnt fuel and it seemed to loose a little power but still ran good. Should I do something else to clean the system? Are the injectors fouled from the bad fuel? Should I add some injector cleaner or fuel treatment to tank? Additive brand suggestions? Thanks for any help.
Cleaner is never a bad idea, but when its at the point that they are fouled, its too late.
Did the primer bulb go flat? if so, its possible your pickup screen is plugged up from the muck?
Was the machine warm and still smelt like fuel? when cold, it will smell that way, when its warm it should be fully burning the fuel.
The primer bulb is hard. The unburnt fuel smell was present when warm. Thanks
That is a possible sign of a bad injector dribbling fuel in and not being burnt. It may pay to get them tested at a deisel injector shop.
I have done a crude test by removeing the injectors and tube lines. Re-attaching the tube lines and injectors so they are hanging out the back of the machine sraying down and crank the engine. Look for any droplets of fuel forming on the injector tip and check the spray pattern.
Crude, but effective.
Ok thanks I'll try that. I should mention that this machine has less than 400 hrs on it.
With only 400 hours, it should be running sweet as..... I hope its something simple.
Hoping its just a matter of running some injector cleaner through it. Havent had a chance to do anything yet.
