Thanks to all for the help. Finally found the correct filter and it works fine after curse myself for trying something different. I guess I don’t know more than the people who built it. My filter was choking it down and not letting enough fluid through because it is a different micron filter...
The filter is on the left side and hooks to a hard line in fluid tank under seat
no it started getting jerky before I changed the filter. Yes all functions are jerky. No on the lower rpm. Thanks for your help
