7.25 EXI kicks back

I purchase a new Briggs to go on an old walk behind weed eater.
When pulling the rope to start this engine it kicks back in the clockwise direction and jerks the rope out of your hand leaving you with pain in you hand.
I have been able to get it running but once its warm it doesn't want to start?
Now the plastic pins that secure the pivot arms in the crank assembly are broke I guess due to constant abuse due to kick back problem.
I didn't pay a lot for it but I thought it would be ok with Briggs name?
anyone else seen this issue and solved it?

    First thing I would be checking is the valve adjustments. Not sure about this particular engine but know many over head valve small engines tend to have starting problems if valves are not adjusted right to spec. Even electric start models will act like a bad starter or weak battery if valves need adjusting.

    You said new engine. Is this new to you or brand new. Also did you the version with the heavy flywheel since string trimmers don't have the extra weight of a blade or just the light weight flywheel?
     
    If used new engine it can be a partial sheared flywheel key.

    Good points, especially about the weight of flywheel. Anyone who has tried to start a rotary mower without a blade knows how important the blade weight is!

    That was my first thought too.
