G'day everyone,
I am wondering if anyone has come across this problem. Fuel in crankcase, I will try to give as much info as I can so please bear with me. A customer brought their Husky ride-on in saying it has hard to start, I checked in out and found fuel in crankcase, drained it out. Filled with new oil and filter still was hard to start. So I then removed engine after reading something on an American forum stating these ser 31 engines are notorious for breaking the de-comp assy on the camshaft. Yes I found broken de-comp on camshaft. I fitted a new genuine Briggs camshaft in engine, put it back together fitted to ride-on started ran fine like it should. Gave it back to customer, he used it for about an hour. It has come back to me again same problem crankcase full of fuel again, so I thought the de-comp broke on the new camshaft. Remove motor, took off sump but de-comp on new camshaft is fine not broken no damage. Also the timing is fine as well. I tested the fuel shut-off solenoid on the carby works fine. So my dilemma is if de-comp is ok, fuel solenoid is ok why is the sump filling full of fuel so it won't start. If anyone has any ideas about this, any help will be truly appreciated cheers Mike
