Kawasaki Fx1000v Engine Problem!

I have been fitting more & more Kawasaki engines because thy are giving 3 year warranties down here on domestic & 12 months on commercial use.
Other engines come from the surplus/ remainders merchants like
Surplus center http://www.surpluscenter.com
Small Engine Warehouse http://www.smallenginewarehouse.com http://www.smallenginewarehouse.com /613777-0001.html
( buy of the month )
Small Engine Suppliers https://www.smallenginesuppliers.com/
Another great deal https://www.smallenginesuppliers.com/shop/html/pages/products/briggs_vertical_shaft_engines4398.html

Note you will have to buggerise around with the mufflers as the muffler is part of the mower and not the engine.
Expect to pay another $ 100 for a muffler, but if you know a welder, or can swing a torch yourself, no problems.
