Question about Briggs & Stratton Briggs Stratton Lawnmower Lawn Mower Short Block

1 Answer

My craftsman lawnmower 917.378941 runs about 10-15 minutes and then dies. I wait about 10 minutes, and will start fine and run approx 10-15 minutes again. It seems like it is getting hot and shutting down. Any advice would be greatly appreciated.

Provided fuel flow is consistant and fuel tank beather is clear

sounds like the magnetron coil assy is going open circuit when hot
replace the magnetron with same type of unit as fitted to engine

two types could be used

1, standard magnetron ( has a piece of card between the halves of the iron lamination stacks

2 advancing style magnetron this unit looks like the standard one
except it has no card and has a wideish back gap at the ends of lamination stack

which ever one is used use same type


here is web site for parts
http://www.briggsandstratton.com/maint_repair/manual_and_more/

enter model and type numbers from blower housing on engine

good site check it out

cheers paul

Voltage regulator


Sounds like a bad connection. The alternator only charges the battery, so if it or the voltage regulator in the alternator fails, the battery would slowly run down, not die all at once.

Briggs and stratton 6.5 Ohv dies after running for about 10-15 minutes. I let it sit awhile then runs again. This is a vertical shaft lawnmower engine.


This is a classic symptom of a blocked fuel cap vent. Next time it dies, remove the cap, wait 30 seconds or so (for carb to re-fill), then try to re-start. If it works, replace the cao.

Instructions for fixing the choke on a Craftsman LT-1000 lawn tra


I have been hearing alot of this problem. Well it is gravity flow. I just bought a 2002 lt1000 17 hp without a carb the guy was having the same problem so he sent the carb away to get checked out and low and behold it got lost. He waited the summer to see if it would show up but it did not. He got mad and bought a new bigger one. Any ways i am waiting on a new one. Now in my reading these problems i discovered that the fuel line coming out of the tank to the carb is lower. Might be somthing to look at. JIM
