My lawnmower has a 16hp opposed twin briggs and stratton motor, i just rewired it and it had ran fine the other day i killed it changed the oil the next day and now it wont start, its got spark and compression with no signs of a dirty carb, it doesnt even react to starter fluid, i cant figure out whats wrong. Any advice would be appreciated.

from my past experiences its probably a seat safety switch, oil sensor shut off, or possibly you just left it in gear? ( which I have done,duh ) both those sensors you can jump. as for being in gear you can just shake your head. ha ha !!! ps ,did you add enough oil also clean the oil sending unit, hope this helps, it sounds like an easy fix, another thought is your key switch grounding out

Since you have done some rewiring recently I would suggest you go back and make sure all your connections are good and tight, no broken wires and all your grounds are good.  As a side note please do not by-pass any safety switches they are there for a reason.

Check to make sure no one bumped the oil sensor wire, the pto switch isn't in gear, the clutch is depressed when it should be, etc...

Are  not most of the safety switches on the starter solenoid side and not the ignition?  If it has spark I would guess it turns over.  If this is true that eliminates any safety switch.  I would put in a new plug as you could have fire with the plug out, but it is not firing under pressure.

Having spark in the ignition system, or not has nothing to do with "turning over"  Not being locked up, and the crank spinning when the starter is activated (pull or electric) is  all that  "turning over" means. Whether it fires, or tries to start has nothing to do with "turning over".

I do not get where people say "starter cranks, but engine does not turn over"  something that I see in many for sale ads and "help-it don't run" kind of  posts.
