Hi! I have the above mentioned Murry Hydro model 42910x92a. It had a bad 14.5hp Briggs & Stratton.

I swapped bad engine out with a 19.5 HP Briggs & Stratton that was removed from a Craftsman T10000 series mower.

19.5hp has 3 wires. one by itself coming from coil and the other 2 wires together in a white pulg in coming from in under flywheel

and i have no idea what these wires are for.

I have gotten it to crank and have spark at both plugs but cranking is slow and will not fire over.. any suggestions?

thankyou

The white plug should have a red and a black wire.
The red should have a buldge just before it goes into the white plug.
The buldge is the diode which changes the power from AC to DC so this wire can recharge your battery.
The black wire is AC and goes to the lights ( if fitted ) via the L or A terminal on the ignition switch.

Now for the tricky bit.
You need the red wire but it is attached to a 1.5mm round pin duel plug.
If you cut the plug off you will have to put the diode back .
Briggs make a epower pack ( for dealers ) with all of these funny plugs so go to one and get a female with a pair of short wires attached to them so you can splice it ito your mowers loom.
Or if you have the mower the replacement engine came out of, cut the plug off it.
Or if your old mower was keeping the battery charged well, pull off the fly wheels and swap the stators over for the old one which should plug back into your mower.
