Small Engines (Lawn Mowers, etc.): Briggs&Stratten /woodsplitter, woodsplitter, head gasket

Question
QUESTION: Hi Folks ; Am working on a friends woodsplitter with a B%S motor,Mod#135202 /Type#0015 01 / Code#9504262E .Has had carb issues.Unit when received would start hard ,idle poor and when splitting wood motor would stall.  We got a kit and I cleaned the unit.New spark plug. Pulled the end welch plug (90deg to the air cleaner) to clean ports . Did the pump diaphram /spring on the side of the carb , cleaned ports with carb cleaner and compressed air. Got the maching to stay running ,ran a tank of "sea-foam" through it. Ordered a small welch plug (not with kit) to access transfer ports on the side og the carb , found restricted , clean and replace welch plug . Now the machine still starts hard and will run for only 30-50 sec. and stalls. Tried dumping fuel into intake before stalling and no change. Tested plug fire right after a stall and seems to have a good spark. The unit is the type where the carb screws to the tank and resivor is in the tank . Pick-up is clean as is the tank.Help.

all being =  with good spark and compression  and spark at right time
sounds like you still have a fuel problem please check with  web site parts ipl  for correct orientation  of sping , cap and diaphram  , make sure mixture jets are clear and adjusted

load could be exceeding power ouput or governor is not
opening throttle plate wider when load comes on  - is governor working , springs located correctly

does this unit have a low oil shutdown unit on it  try disconecting low oil level wire from kill  switch ?

make sure the engine does not have a intake or ex valve leak  or burnd valves / blown head gasket ?

if it does loss of compression / loss of fuel from combustion chamber / lean out of fuel mixture


recheck carb 1st then governor

QUESTION: Hey Paul ;
A quick follow up on the woodsplitter.I did a compression check and discovered the motor was plain worn out. With the direct coupled pump the motor felt like it was still tight. With the muffler off I could poke a screwdriver in the exhaust port and with the valve off the seat I could wiggle the valve stem showing the guide very worn.I had about 10-15 psi on the compression guage. I have a splitter with 2 hours on it and showed 60-70 psi on compression. Thanks again Paul. Carl

Answer
hey  carl

engine load exceeding power  ( or lack of power in this case ) compression too low

remember  THE   F  A  C  T  S  

F = FUEL
A = AIR
C= COMPRESSION
T = TIMMING
S = SPARK  @ RIGHT TIME  


GLAD YOUVE GOT IT SORTED

CHEERS PAUL
