So, could it be that the gas cap is the trouble. ? If the pump is creating vacuum, and the cap is restricted it would cause vacuum in the lines. Maybe pulling air in. And yes then the engine may not run long if it starts. But once the pump is pumping gas it could create more vacuum to over come the restricted gas cap allowing the engine to keep running. More vacuum with liquid than air.

Another ramble.

Good point Noel, wouldn't hurt to take a closer look at the gas cap. I will do so, thank you for the ramble, as always!

So now it started on the first key, go figure! Maybe it was upset with me for not giving it a bit of attention! I love this 444 the way it purrs now! I want more seat time!!!!!!!!

And yes that too is possibility . A lot of the new riders have a large cap where the venting is through little groves above where the rubber seal sits. I have had people who have tightened the cap so hard in the heat that they blocked off the venting . The older metal one I have seen bugs build nest in the cap as well .

The barn find rear oil, not really surprising! This is the very rare good old red oil, they don't make it like this anymore.

How much oil did it take to refill the rear end Eugen ? I need to do my 446 some day.


Noel

If you could find one of these fuel pumps Eugen. It would help with starting. This is on my sons MF 16 we got recently. The fuel pump has a priming handle. I’ve never seen one before until we got this tractor. Just noticed it last week.

Here is a trick to clean the inside of a transaxle when like that without taking apart .
Drain as usual , jack up rear and put on stands with rear tire just off the ground . refill with 5w30 oil .
Start engine , at idle in high put in full forward and allow the oil to splash around in side cleaning . about 10 min should due
Never do this under load, always on stands
put back on ground , drain and refill trans axle with fresh oil .
I use 80w/90, some use 15w40 , 20w50 , or 75w140 synthetic . each has there own merits depending on climate and type of use .

Not exactly sure Noel, but less than 4 litres, and more than 2.5 litres.

Good tips @DavidBarkey thank you! In the big tractors some people do the same thing with diesel fuel for cleaning except they don't lift the rear.
