Cub Cadet 1650 engine trouble

[landscapebygd]

I just want to confirm one thing the fuel cap on the cub cadet 1650 is designed to vent correct ?????

I just saw a fuel cap on Amazon that looked identical to the one on my cob the description said nonvented so I just want to be sure of this so there is no confusion

i'll keep you all updated soon.

Ah, no needle nose pliers. This is the tank assembly. The valve pulls out the bottom of the tank...

FWIW:
The early 1650's had a small gas cap and tank opening.
Later ones were bigger, so if you are considering a new cap, just a heads up.
And as zippy mentioned, the screened petcock pulls out the bottom. it is in a rubber bung.
Get a couple of bungs, as they all harden and crack over time.
I usually pick them up @ tractor shows for a dollar or so.
Don't try to reuse your old hardened cracked one, because it will leak.

Depending on the serial number of your tractor, there are are two possible options.

S/N 560209 and below is part number IH-61635-C2 and looks like the top picture.

S/N 560210 and above is part number IH-109037-C! and looks like the bottom picture.

Give us your tractors serial number and post the link to the one on Amazon and we'll help you decide.

Best to measure the neck opening to be sure.
After 30+ years you never know what a previous owner did.
Just like in my case, an old style small neck tank was replaced with a later,easier to fill, non leaking tank

I had the same bogg down and die issue this spring. Tractor ran great for 15-20 minutes then bog down and die. I took the ingest route to the simplest fix.

I drained and cleaned fuel system and carb. No improvement .

Replaced coil and condensers. Still no improvement .

Pulled the head and valve cover to check for sticking valve. Valves were fine.

After all of that work, I adjusted the slow and fast idle screws 1/8 turn each. Problem solved.

The top picture is of a brand new IH-109037-C1 cap for a 1650. Notice the hole circled. It lets air in that is passed thru behind the gauge face through the opening where the spiral float shaft spins. Make sure that little hole is open.

I wish someone had suggested a gas cap earlier.
