Hi, We purchase a Takeuchi a year a ago and the dip stick broke off in the sump and the machine was over fill in oil which is why we had to replace the head gasket and get the head machine. Now our problem is that it does have power when under load (pushing) The air filters have been change, The fuel filter has been check, The values have been check and adjusted, The turbo has been check and still having issues. At a lost what to do next and doesnt seem to be many dealers in Australia that know to much about Takeuchui TL 230 series 2. Any feed back or advice would be appreciated
