Question about Sport & Outdoor - Others

Open Question

I have a Walker Mower with a 20hp Kohler Command engine.. 850 hours on it.. I bought it used from a home owner.. This machine is using about a quart to quart and a half of oil on a full days use... it doesnt smoke except when the motor idle is changed during use.. or only for a brief second on start up or shut down... i have no Visable leaks. its been serviced by a walker dealer. new air filter, fuel filter, and oil filter and such...I was told that this could be a pcv valve or something to that point or even the valve guides.. if so .. where is the pcv valve ? Its not listed in the Mnaual.. and if the Guides are bad.. how serious of a fix is this..and what will I be looking for as a payment for fixing this problem....I was told to use straight 30 weight oil to help with this problem...should I be worried about this motor failing in the near future? thanks.. DAVE from Maine.

SOURCE: how to replace a PCV valve on my 1997 dodge neon?

Once you have the new PCV valve locate the old one on your engine. It will sit on the middle of one of your valve covers (most likely passenger side) and will have a line that connects to the top of the valve. Simply pull the old one out and put the new one in snapping that line on the new one. Should only take about a minute to do. Hope this helps, let me know if it does.

If you are using that much oil you either have a BIG leak or your BURNING oil through bad rings

SOURCE: Riding mower engine loud and smoking.

take it to a reputable shop and have them check it over - courage engines had a problem when they first came out - the bolts in the cover plate were not torqued properly and when they come loose, the torque of the engine turning will crack the block - this should be a warranty condition if the block is cracked - just make sure the shop is a kohler warranty station

Hi, i have a 20hp high out put motor in my mower and it will only run with the choke out then it bogs down and stalls..checked fuel filter and its clean..any help would be appreciated..thank you

Most likely it is some sort of gunk in the carburetor. if it has been stored with gas in it this can cause this problem. You can try a strong dose of carburetor cleaner in with the gas. (Use fresh gas in the tank). and see if that helps. give it some time, but It may need a new carb or a rebuild.

Have a brand new Husqvana with a 20hp Kohler V twin engine. Is it necessary to run the engine in? Nothing in the manuals about running in.

it doesn't hurt to ease it operation wise into service,but for sure do what the owners manual says to protect your warranty,and change the break-in oil soon to remove any machine shavings from the unit during the engine manufacture process
