Looking for any suggestions. This video was taken without header on. We have cut 100 acres since this has been happening. Oil level has not dropped. We have changed both fuel filters. We did have fuel issue before this started happening but was solved with filter change by tank. When in operation it only occurs for about 10 seconds especially on incline or when pushing hard and then returns to normal.
It sounds like a relief valve goes of towards end of video which changes the tune of engine????
any thoughts would be very welcome.
thanks
