Hi Moki 1.8, I have had three Brison 2.4's and three Brison 3.2's at one time or another and they all ran like a top. And I mean they were perfect from the time I opened the box. Yes things have worn out like bearings, rings and carbs but I always got superb service from the guys in Dallas and now BJ's Engine service. I know it's difficult to spend another $200 to $300 dollars on an engine when you can get one so much cheaper. Check on those Chinese engines. They come and go on a regular basis. Some are good and some are bad according to the posts and the experiences I have seen at my field. If you want to have a trouble free engine, I recommend the Brison. Dan.
