Working on a Ferris walk behind comfort control DD. Push the forward motion bar down/forward and the mower goes fine until I turn either way. When squeezing the right or left turn lever, the forward motion bar returns toward the stop position, causing the machine to nearly stop. If I hold the bar down/forward, it works as it should. Is there an adjustment to stiffen or tighten the return on the bar or another remedy this problem? Thank you, gregjo1948
