I recently picked up a 1994 (I think) 416 H. At first I was going to sell it, and had it listed briefly. Then I decided to keep it and fix it up. I got it running, fixed the electrical problems, changed the axle seals, fuel lines, fuel filter and intalled a new idler pulley. I was able to mow with it for about 1.5 hours and it did two things I didn't like.
1. It picks up speed going down hill unless I move the motion control lever back to slow it down. ( I hate the lever). I changed the oil (had ATF in it). I need to change it again and change the filter. The hydro is strong when hot.
2. The engine at one point began to rev up for no reason. I shut it down, and then after stopping and starting it several times it ran normally for the remaining 45 min it took me to mow the lawn. Possible governer problems? I stil need to change the oil and filter. Should I use synthetic oil or run some sefoam in it and see if that cleans up any debris in the gov. The oil thats in it now doesn't look that dirty but I know its needs to be changed. The engine is strong and has 120psi in both cylinders. Any advice is appreciated. Thanks.
