However, sometimes when I start to let my foot off the clutch when it's in gear, it will sputter a little. Or when I crack the throttle open, it'll sputter a little. It seems to do so more recently when it has been really nasty hot and humid. Am I getting moisture somewhere? Should I flush my gas tank? Any thoughts? I know it's a pretty vague question, but the tractor runs well, it just seems to have a few hiccups once every couple of runnings, for whatever reason. :oops:
 
How old is the distributor cap?? How about the rotor. both do not like humid weather and both like to crack and can cause a problem like that. I could tell you an easy way to find out but if I did you might get mad at me LOL. Just grab the distributor cap with it running. If you jump 10 foot you know where your problem is

They're probably 20 years old, easy.

Not really wanting to take a snap from the energy circuit, heh.
 
Hot humid and old cap yep you probably need to replace both the cap and rotor. Now I'll tell you another way to maybe see any crack is might have that would cause that problem. Spray the inside of the cap with starting fluid and let it dry. If you see any lines after it dries those are cracks and a cracked cap can/will cause many funny problems
 
Run it in total darkness and watch the entire ignition system. Goose it a few times. Do whatever is necessary to get it to sputter. If you see fireflies then you know your problem. "You can observe a lot by watching." Yogi Berra.

Fireflies would wind up meaning bad rotor/cap/condenser/points? Or something else far more serious?

I have run it in total darkness before (a few weeks ago) and I haven't had a problem with fireflies shooting out of the exhaust before (I'm sure if you went from full open to idle in an instant it'd pop like that, though)... I'll have to try it again and check sometime, though, just to make sure.
 

Fireflies..???

The WD of my Grandad's and Dad's WD-45 (and all the neighbor's WD-45's) all spewed fireflies at night..!!
They would Stand Blue Flame about 14" above the Muffler when working hard and the top half of the muffler would be cherry Red..!!
That was why they seldom were used with a manure loader...!!
Most all around here had us clean manure out with our JD "B"..they don't spark like that..!
Never thought it could have been any problem...
I wouldn't think carbon sparks would be unusual for them..

If it stumbles after it is warmed up, have you tried setting the Power screw richer..??
You may have it just a tad too lean..

I was referring to electrical sparks in and around the ignition system. Sorry, I thought everyone would think of that. It was quite a common phenonomen in old cars. Turn off all the lights, open the hood and watch the "fireflies" dance around. Modern ignition systems have pretty well eliminated that problem.
 
Runs great 80 percent of the time sounds like a great tractor for me . I as well like to rest 20 percent of the time.
 
(quoted from post at 22:17:45 08/03/10) I think by "fireflies" Bill meant sparks jumping around the plugwires, distributor cap, etc.

Ooooooh.

In that case, no, I had it out at night the other day and didn't see a single thing out of place when driving it. Even got off and walked around it.
 

Different fireflies...!!!

Musta been a Senior moment..Duh,,!!!!

I agree, that is a great idea and almost as effective as Grabbing one plug-wire at a time..!!!!!

Remember the Clear Dist. caps that you could see the inside of the Dist, as it was running..??

You could see sparks in it too and seemed very interesting..!
