D160 opinions

[1maidenfan 202]

I have been mowing with my D160 with a 60" 3 point mower. Not sure if the 16 hp onan has enough...lets say power, to turn that size of a mower deck and pull itself? When I am mowing the engine runs fine for about 20 - 30 minutes then acts like it wants to die (like its starving for fuel) so I turn the clutch off (electric on a D160) and idle the engine down and it starts running ok. So then I idle it back up with the clutch on and runs fine for 20-30 min and does the same thing over and over. Gets pretty frustrating trying to mow like that. I tried adjusting the carb, before start of season I cleaned the tank out, changed all fuel lines and filter. Pump seams to be working fine. Don't know much if anything about the onan carb but I did pull the cover off the side (float bowl cover) cleaned what I could. Seams to run just fine till I put it under a load.

ANY THOUGHTS, SUGGESTIONS OR REMARKS SURE WOULD BE HELPFULL.

Thanks

thats a lot of deck for a 16 hp but it still shouldnt run that way probably needs the carb cleaned really well which is a pain in the behind

That is one of the strangest looking carbs I think I have ever seen?

It could be a carb issue like mentioned. How deep and thick is the grass you are cutting? It would be interesting to know how hot the motor is getting. I have mowed with a 520 with a 60 inch deck thru thick grass before and it seemed more than adequate, it would bog down a little in the real thick stuff. A 60 inch deck on a D with a 16 does sound like an awful lot too ask for? How long have you been running this combo?

Just recently picked up the D160 and started using it this year to mow with. I had been using my 18 auto but it is in the process of a complete restoration and probably going to be my "trailer queen"

I dont let my grass get to high before each mowing, maybe 4.5"-5" tall and have blades set at 3.5" cut. It hasn't been bogging down it just wants to stop running, like its out of fuel. Will be tearing into carb real soon and change filter again just to be sure. It does seem to be pretty hot but trans is not.

Are you maybe vapor locking the fuel system some how? Like a fuel line collapsing and then when you idle down you get relief? A partially clogged fuel filter? Partially clogged hole in the gas cap? Those are just some of the things I can think of, good luck, Chris.

You might have something with the "vapor lock" statement. One of the times it wanted to stop running I opened the hood and heard a gurglling sound, kinda like something boiling? Fuel I would assume. How do you prevent "vapor lock" on a mower?

Would changing the exhaust from a 2 into 1 system to dual stacks have anything to do with it?

Thanks for the info.

is the fuel tank able to vent? Maybe try not tightening the fuel cap all the way so it can vent the tank, I have had that problem on a gas powered air compressor before.
