A Note About Warranty !!!

We just spent a lot of money repairing 5 engines customers claimed were defective. One thing we discovered is ALL 5 had installed a new China carb or fuel pump. Upon inspection all were assembled properly and all clearance were correct. We follow all warranty same as specified in Kohler manuals and it covers defects in material and  workmanship. Nowhere does Kohler state add junk parts and if it damages we will fix it and neither will we anymore. We now put a note in all engines stating this. These aftermarket parts leave a very distinct tell tale signs so its easy for us to tell. We tested a fuel pump customer left on his 14 hp when he returned and we tested volume on our test engine. ( pump didn't even pump enough fuel to run a 5 HP engine. ) This raises head and exhaust temps 300 to 400 degrees which does serious damage and that is never warranty.
