how do you turn your oil pump down exactly? i just rebuilt the top end and the sheet that came with the pistons told me to run my first tank of gas 50:1 mix so im going to let that run through before i start messing with anything

Since your running pre-mix in your tank, your going to have more smoke than normal. I wouldn't worry about it. You can check to see if your oil pump is adjusted to specs. Full throttle and the line on the lever should match the line on the housing.

With oil in the gas and feeding from the injection pump you will be 25:1 or less, this will make lots of smoke

Running lots of oil leans out the engine, it does not richen the fuel mixture. Extra oil is good for breaking in a fresh rebuild and so is extra fuel. I'm assuming it is a carb and the smoking is most likely it being over rich because it is warm out. Smokey exhaust is way more often from an overly rich fuel mixture than it is from a little too much oil. Don't be concerned about it until it is cold, but then you'll have to differentiate between normal exhaust and smokey exhaust.
