Super 2 oil line question

[flatsfisher]

putting this back together and I hate to admit it, but I can't remember if the oil line in the tank with the duckbill is supposed to be where I have it or down in the oil. or maybe it doesn't matter. assume this is the line that pressurizes the oil tank. thanks.

I believe you are correct:

 

[flatsfisher]

thanks. the old lines were just goo.

If you haven't done it already, be sure to remove the cover and check the diaphragm above the bar pad. It doesn't hurt to shoot a little brake or carburetor cleaner through the outlet to make sure it is open. I had one earlier this year with a stuck check valve in there, drove me buggy for a day until I got the check valve freed up.

Yes, correct in the installation of hoses. I still haven't figured out what keeps the air filter in place on those things..

Mark, is this what you are referring to?

it's just jammed into the case with the engine and has a plastic plate in front of it. looks like a pain to clean on a regular basis. thanks.

It seems to help to loosen the oil cap after you're done using the saw. It relieves the pressure in the tank to keep from oiling down your floor or table, etc.

 

[flatsfisher]

sounds like a good idea. thanks.

Ditto on the good advice to loosen the tank’s cap after done cutting. Just remember to tighten it up again before cutting again. I learned the hard way.

 

[heimannm]

ff - yes, behind that cover is a spring, gaskets, and the diaphragm though the IPL calls it something else.

[flatsfisher]

thanks, I will check it out.

is it ok to run this Super 2 at 50:1 using full synthetic premix oil? I know what was recommended back in the day, but the modern oils are much better.

 

[heimannm]

I run all of my 2 strokes on Amsoil Saber at 40:1, leaves a little more margin for error. I have not had any issues with carbon or oil fouling.

40:1 sounds like a good plan. thanks Mark. back in 2006 or 2007, Mobil stopped making their MX2T fully synthetic premix oil because 4 strokes had taken over the dirt bike market and I guess sales plummeted. it was being sold at all the auto parts stores and they marked it down to 1 dollar a pint and 2.00 a quart. I had been using it for years in my bikes and power equipment and knew it was good stuff, so I went around to about 6 stores and bought everything they had. I've used about half of it, and this is what I still have left.

Gravity and shape keep them in place. That's about it. When that filter gets old, it collapses and falls apart like a worn out sponge. Replacement is a must, and I've usually made some rather good ones in the shop. Luckily, I've never had to make a bunch of them.

 

[flatsfisher]

I suspect a piece of a Twin Air dirt bike filter would last longer than the purpose-built filters esp the AM ones.

got this thing back together today. cleaned and kitted the carb, new lines, new gaskets. still does the same thing it did when I bought it. squirt mix in the spark plug hole it fires up, runs a couple seconds, even revs and then dies. squirt some more and it fires up again. I just put it on the bench in disgust LOL. will give it some more hell in the coming days. got a few things going on. raining and raining here. makes us get out in the woods to ride our bikes while the sand is wet. mo traction.

 

[heimannm]

Frank - make sure the carburetor gasket is correctly aligned so the impulse hole is open from the manifold to the carburetor.

A leaking crankcase or faulty reeds would also result is a low impulse signal that could prevent the carburetor from pumping properly.

good morning, Mark. I believe I got that right but when I did the kit for my 028 Super, I screwed that up and had to do it twice LOL so you never know. the reed appeared to be lying flat and tight. I should have known enough to replace the crank seals, but I did a pressure test a couple of weeks ago and it was ok. might get back to it today. thanks!
