Hey everyone
Picked up a 88 savage that I'm working on
Here's the issue I'm having
The air box was full of gas so naturally I thought it was the needle seat
I swapped out the float needle and seat, cleaned oit the carb and no luck
The petcock is an aftermarket one with on off and res so i think that rules out the bad petcock option
The gas/oil mixture is spewing out of the pcv valve, the large hose that normally goes into the air box
I thought it could be the float level possibly but I haven't checked it yet
It only leaks after I let off the throttle, with the throttle pulled it won't leak but when i let off it spews it out of the hose
What are your thoughts?
I know I need to change the oil of course, just trying to figure out the problem before ruining more oil

Like Oldnslow said you need to check the oil level and take off the filler cap and if you smell gas ,for god 's sake dump it ! gas is a very poor lube . assuming the petcock is good (pull the hose of the carb and be sure it isn't leaking by when closed)  plug the vacuum port and make sure you set the float in the carb (you replaced) to the proper height , that and the  O-ring that seals the float valve seat to carb body are the only things that will allow it to flood. Set your float level(very important) first before changing your oil.
