OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines BRIGGS & STRATTON

I have a 8HP and a 11HP briggs electric start motors they both seem to have similar problems starting In that as they crank and come up to compression they just stop turning and the starter has trouble getting over compression, This is with a very good battery (car type) some suggestions please. I have checked the key on the 11HP and replaced it as it had some damaged but was not sheared and did not help.

I have tried to crank with spark plug disconnected to see if it was firing to soon and same condition prevalies

Darrell,
I would suggest to remove the spark plug and turn the engine over as I think that you have either excesive fuel in the cylinder or oil which is causing your problem.

Regards,
Bruce

Darrell,
If Bruces suggestion doesnt help, There are several things that can cause this problem,starting with (like Bruce said) "over choking" also,worn rings, (does it smoke,or/and does the spark plug foul out quit frequently?) a low battery, a worn starter (or pinion gear) a loose starter or loose battery cables ("check both ends of all your cables") FOR A QUICK TEST ON LOW VOLTAGE, JUMP START IT WITH YOUR CAR OR TRUCK,and see if this makes a difference. If it doesnt, check to see if the altenator wires are connected. On the opposite side of the Carb you will find 2 wires if you have head lights"red/white, if you don`t you will find 1 white one coupled to a plastic connecter leading up to either your ignition switch or to the solenoid.

Seems to me that since you are using a known
good strong battery that the trouble is going
to be with the starting system, most common
would be that the plastic pinion gear is
locking into the ring gear on the flywheel,
usually caused by a worn or broken pinion
gear, take the plate off that covers the starter, do not remove the starter , and see
if this is the case. If not, then you could
havc two bad starters.
