Aroostook,

LOL, I hate to agree with you onyour first post...

I do agree though, These old IH Cub Cadets ARE pretty simple (for the most part). All they need is fuel, air and fire, and if everything happens at the right time the engine will run.

To me, white smoke is a sign that there IS INDEED fire (and fuel) in the hole. After that it is a matter of; is it enough fire, at the right time and/or too much/not enough fuel and air.

And yes! It could very well be an electrical problem.

Ok, I will try it out this week. Time is so hard to find lol. I'm hoping it's only the points. I've already dissasembled alot of the engine and reassembled it.

The only time I couldn't get my 109 to fire, it turned out to be the starter/genreator. It was drawing so much amperage there was not enough left to the coil. The armature was shot.

Hmmm. Now that I think of it my Starter/Generator is also having issues turning it over at times. It keeps coming loose or something cuz the belt just slips and the starter spins out. I'm stumped.

take the spark plug out, connect it to the wire, alow the plug and wire to lay on the clutch shield, or some where low. crank the motor, you should EAZILY see good spark comming from the plug. if your not getting spark at this point, you found the problem, it could be a bad plug too, with all that gas soaking it. i'd be willing to bet that you were turning the screws around on the carb and now they are all out of wack. if you dont have the high speed mixture screw and the idle mixture screw set properly [air/fuel mixture] you will never get cubby going! i'am thinking, how you got white smoke with no spark. i dont have a carb. adjustment for your cub. clean and inspect those points, look for any build up or pitting-note where the build up is at-on the moveable or on the stationary contact. spark plug gap=.035" and point gap=.020" . hope this helps.

Hmmmm, I didn't play with the screws, but my "bud" screwed around with the idle mixture screw over summer. And that could be the problem right there. If thats what it is then I'm gonna give my "bud" hell and having my cubby run will make my whole week alot better. Thanks for the info Johncub. Thanks everyone for their posts.

Is this normal: Every five sparks (while looking at the points) there is a blank, and then five more sparks and then a blank. And now there's no smoke at all. Yes there's gas. This Cubby is such a pain LOL.

5 sparks and a blank...hmmm. You've come across the bestest reason going to have 2 or more Cubs. Parts switching. The good news is, you have spark at the points. Now, pull the plug, ground it and crank her over. Same spark? Good spark? Even new plugs can be bad, right out of the box. Plug wet? Plug dry? Followed all the preceeding carb suggestions? Both needle valves backed out 1 1/2 turns (for starters)?
Have you got a spare coil and condensor? That 5 sparks and a blank is strange, but I don't think it would keep her from starting - and then running rough. Also, without digging out the Book, I think they fire every other revolution. Please say you have a manual!
Isn't there a tractor show in Eliot each year? (I'm trying quick reply, watch me screw it up)!

The plug seems fine. After charging up the battery it's sending out a blue spark now. I will try the carb work. Me and my bud worked on his simplicitys yesterday and we tuned the carb as it turned over and the tractor started. Would this work on the cub? And unfortunately I don't have a manual. The guy I bought it from (one of the head members of the tractor show) didn't have it. And yes there is a show in Eliot in June. This year is June 23-25. You should come down and check out my cub that's being a big baby right now LOL. She will be at the show. But yah, I will try both the needle valves. I'm really thinking it's the carb. How should the idle screw be set? At how many turns anyways? thanks Aroostook. Good job on OCC so far hah. Thanks for the help.

Smile Carter Carb Needle Valves

Try turning both screws all the way in - not tight, just a little less than snug, then turning them each out 1 1/2 turn. While you're right there, wiggle the throttle shaft - that which the throttle linkage attaches to - runs vertically through the carb. If it feels sloppy side to side you're sucking extra air, there. Whole new subject, I know.
The fresh charged battery makes a big difference, doesn't it?!!!
I'm going to Buxton this weekend to pick up a 1811w/450 snowblower. 6 hours, one way, or I'd look you up! Getting an engine going over the internet is like trying to tell someone how to whistle by mail! Frank

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
