Well i know how to prime an engine but only for pull start one is it the same way for a non pull start cause i don't really know. do you hold the stinger or whatever and put it on a starter box then your done. please help

P.S. no manual on engine or for starter box i guess i lost it

Yes, you can prime it the same way as a pullstart OR you can hold the stinger and put it on the starter box but I don't like that way cause your turning over the engine with no oil in it and also it is easier to flood the engine. I like pinching the pressure line and snaping the fuel tank lid. It is fast and also does no harm to the engine.

It doesn't matter if it is pull or not except that method 2 ibnvolves a starterboxc or pull starter.
1.Push primer button
2. Hold stinger and either pull the starter or turn the starterbox over a couple times.
