Cub fuel issue??

Postby Denny65 » Mon Jun 08, 2015 1:21 pm

Hi guys, I've been following this board for the last year since I purchased my first Cub (52). Great information, it has helped me through a few problems. To get to the question, when I purchased the Cub last summer I gave her a bit of a tune up. New plugs, plug wires, coil, distributor, rotor. New sediment bowl. Haven't had as much as a sputter! Been running great! I was mowing this past weekend and I noticed as I would go up a hill she would act like she wanted to cut out. Was like a Roooom.....rooooom.....roooom... when I would level out it was fine. Does this sound like a fuel issue? Water in the gas? Thanks in advance for your thoughts!

Enough gas in the tank...don't forget that the fuel strainer has a 1/2" nipple that sticks up into the tank. Don't ask how I know this :)

Ken's suggestion is a good one. Also check for debris floating in the tank.

Thanks guys! I'll let you know my outcome. I'll be awfully embarrassed if she's out of gas!

Denny, I don't consider running out of gas half as bad as forgetting to turn the gas on. :oops:

Okay, I was going to start a new thread.
But here's an excellent place to post this.
I've been thrilled by the power of my 49 cub and the used Woods 59 I got from Bill Hudson - I think I got it from Bill.
Actually able to mow UP a fairly steep grade in tall moist grass.
Then I got this snowplow - a Cub 54 blade.
Did a wonderful job last winter - was thrilled with the power.
But grass mowing season comes late here in the North Woods of Minnesota.
So a week or so ago, I sharpened up the blades, cleaned up and lubed up the spindles and reinstalled the Woods 59.
Started her up and engaged the PTO and nothing. Killed almost right away - no power in the tractor...
So, I checked and re-checked everything on the mower. Dropped the wheel weights. Scratched my head a lot.
Went to Napa and got some sparkplugs and looked all over to find a 7/8" spark plug socket. Closest I could come is a 7/8 6pt deep-well 3/8 drive.
So I went to work on the plugs. I used almost every 7/8" tool in my toolbox removing those rusty bits of steel and porcelain that used to be spark plugs.
Got 'em all out without twisting one off - without taking off the hood yet.
Gapped the new ones and spun them in, hooked them up and still -
no power.
So I dumped a can of SeaFoam in thinking it was winter time gas,
and then I looked at the air cleaner bowl.
It was full of krud and WATER! Who'd have thought?
Cleaned out that mess and refilled with fresh 10-30 and you know what?

The power is B - A - C - K !!

Better than before because of the new plugs...

LOL! Been there, done that, and even got the T shirt....
Everybody always thinks the 3 things: fuel, spark (at the right time), and compression... but always seems to miss the other obvious - It has to breath, whether inhale or exhale...
Glad you got it figured out before you went serious on it... :D
