hello guys let me ask you all a question one of my commercial cutters came into my shop on sat. his exmark turf tracer had a locked up engine. i check and find no oil and no leak. i tell him i will tear it down and see if we can fix it. on monday he calls and i explane to him his kawasaki was junk (rod broke,cam journal broken) he said he would call me back. tuesday he calls and said to short block it. i tell him kawasaki has no short blocks the dont make them only engines.he gets mad as hell and tell me to get him a kohler 23 hp a.s.a.p. so i have one overnighted at lunch the next day he comes to get his mower and i charge him $1875.00 he goes off in my showroom that is full of customers and said he wont pay it and stormed out to his rig five minnutes later he comes back in and wants an itemized bill. i give him one 1- kohler 23hp engine 1499.00 3 hr. labor 165.00 2 qt kohler oil 7.00 freight 70.00 1- choke cable(exmark) 14.00 with tax and enviro fee's it came out to 1875.00 do you think i charged to much i mean i could not have done it any faster.and it was done right.....the first time i moved him right to the front of the line. this guy has bought 3 mowers in three years.buys all his trimmer line.mix oil and parts from us and hate to lose his business but i think that is what has happend what else could i do????
