I filed an insurance claim after the buyer said he didnt get his 660s. He had me send them to his brother. The post office will not honor my claim because they said they delivered it to his brother, his brother signed his name. The postal service is now ready to move in on the buyer and his brother for requesting that I file a false claim. Alabama Walker used his carb for over 3 months till the end of the racing season. He then asked for a larger carb for his new motor and wanted to trade in the rebuilt 650 DP I sold him. He also wanted full price for his now used 650. Then he asked for a full refund trying to tell me the carb didnt work as claimed. I offer only a 30 day guarantee not 90 days. Some people just cannot be satisfied. First he wanted to trade in the rebuilt carb he used for 3 months and when I would not give him a full refund on the trade he claimed the carb never ran right and threatened to ruin me if I didnt refund his money in full within 7 days and he would then return the 650 after getting the refund. Yea right!!!
