john deer fuel issues

Got this mower for free from my BIL. It's in decent shape, runs well once started. But when the weather was cold it would crank for over 10 seconds before firing. But always started, and if i turned it off, it would start back up in a jiff once warm. At the end of the season I went to drain the fuel system, I snapped a tit off the fuel pump. I ordered a new one but didn't try to install until this spring. Went on fine, but noticed some dry rot in the (vacuum?) line from the valve cover. Slapped a bit of electrical tape on there thought I might get it started but no, she just cranked and cranked. Going to order one of those now. Am I right in thinking this small dry rot in the vacuum line would create the starting problems mentioned above? Figured I would replace the fuel filter was I was out there and, even though the tank was full, no gas flowed out of the fuel line once the filter was removed, I mean like a spits worth but no flow. 2) Shouldn't gravity play a role at least to that point? 3) Is there a block in the line somewhere from the filter to the tank? Thanks! submitted by /u/Rude-Ad2519 [link] [comments]

  1. Am I right in thinking this small dry rot in the vacuum line would create the starting problems mentioned above?

Figured I would replace the fuel filter was I was out there and, even though the tank was full, no gas flowed out of the fuel line once the filter was removed, I mean like a spits worth but no flow.

3) Is there a block in the line somewhere from the filter to the tank?

Thanks!
