I took apart the oil pump on my sled and made sure every mechanical piece works and stuck it back on, hooked all the lines up and pulled the cord a few times, should oil fill up the lines when the engine is off? The shaft still turns when the engine isn't running but no oil flowed through the lines.

You have to bleed the air out of the line to the pump. At idle, the pump barely moves any oil. For safety, mix a tank full of gas at at least 75:1 till the pump starts moving the oil.

 

[Bearded Fish]

Ok I planned on 50:1 since it has new pistons, just rev it up until the lines start to fill.

Actually wire the pump lever to full open until the oil starts to flow.
This way you will not have to run it as long.

How often should you clean the oil pump?

 

[Bearded Fish]

My oil pump had never been taken off since 91 and it looked fine when i opened it up, there was no debris or shavings in there but I'm not sure what the proper protocol is.

 

[kccats]

Never, did you remove the pump or pull it apart? If you had it apart, I would replace it!

 

[Bearded Fish]

Really? Every piece was made of metal and the only thing I could think of replacing would be the little gasket that is in between the pump and engine which in my case wasn't damaged.
