I have a D105 JD riding lawnmower that has 38 hrs stop it after cutting yard a that time running grate. Next time went to start and got it running engine surged at all speeds---- checked all lines to carb, replaced fuel pump and filter checked plug and used a new plug to test run, all fuel clean no debree in tank everything looks good, still runs the same-- used a small gas can run a fuel line to pump and tried again still the same ( the reason I am doing all of this is the JD dealer made it plain that pretty much warranty would not cover the problem due to fuel if you know what I mean) so took carb off it looked new checked and blew all bleeds and jet holes and checked needle and float all was in new order put back together and run the same, any good suggestions
Thanks DRY
