Suzuki 2 Strokes

the oil pump actuating arm on my T500 wont fully return.
what is holding it in place.
it had new seals put in etc but the pump arm stick just about half way.
open throttle no problem but shut off it will only return so far.
I know I've repeated it a couple times but just in case you dont understand the 1st line.
check on google plenty of info but not on how to take the pump arm out.

I had a similar issue with my oil pump as well. I just took off the lever and cleaned it really well and lubed it. The PO had put a spring to pull it back but I did not like that look at all, so I eliminated it. Good luck.
