I orignaly ordered my so called 80cc engine on April 13, 2008. As many of you know i only recently discovered that I was sent a defective carb. I emailed them yesterday with a pic to prove my claim and they are going to make good by sending me a new one!'' I know from personal experience it definitely helps that i did not give them a rating on ebay yet, and yes I will wait till I receive the new one! I know this because I work for a very large online retailer, that sells anouther type of product. I did order a better one but it is always good to have spares!
