Pony runs only at full throttle, rough idle

Tiller starts easily, but will run only at full or near throttle (fast). Even at full throttle, there is a mild but noticable 'miss' or 'cut out', which causes the governer to give it a boost, this happens avery few seconds. If throttle is pulled down, it will get rougher until it dies, will not run at all on 'slow'. This is with it just sitting and running. If I try to till, it does it worse, the tines will slow down and engine labor, till the governer gives it another boost at which the tiller jumps out of the ground and tries to run away. The carbeurator is not the kind with a bowl, which I'd know how to take off to clean out any blockage. I'm not an experienced mechanic, just a fairly handy lady gardener...any help appreciated before I have to take this thing to a repair shop.

First, check the fuel lines for cracks/breaks.

If they are o.k., then you will need to disassemble the carburetor and spray with carb. cleaner. Make sure the small screen in the carb. is free of debris. Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152), to clean the small portals in carb. If the carb. has a foat, then you can use the Den tek Brush on the jet as well. Reassemble and start.

(NOTE: If the cleaning doesn't work, then buy a carb. kit and replace all appropriate parts.)

If you need further assistance, just let me know.

From what I read you need a new rewind clutch and the spring and cord go into the housing. Briggs is easy to fix. contact me at [email protected] and I can send you what you need or you can send it to me and I will repair it very cheap!! Parts are available at almost any small engine parts place.

SOURCE: Where is the model number on my troybilt rear tine tiller?

If it's as old as mine (circa 1976), it's stamped on the casting right below the T-handle that allows the handle bars to pivot (also the gear case fill cap)

SOURCE: troy bilt pony tiller will only work in reverse

These kinds of problems almost always require opening and inspecting the gearbox. Hopefully if you can do this is will be something simple you can repair. Good luck.

SOURCE: I recently bought a second hand pony garden tiller

Hi and welcome to FixYa. I am Kelly. You did not mention engine size but most of the "Pony" Tillers had a 250 cc Briggs and Stratton engine.

The owners manual is here::
http://www.troybilt.com/wcsstore/TroyBiltUS-CAS/Attachment/ownersManuals/tillers/769-03556.pdf

If you download the manual on page 23 figure 7-6 you will see the WHITE oil cap on the right side of the engine just forward of the belt. Unscrew that by placing a screwdriver across the 2 raised tabs IF you can not get it loose with your fingers. There is a dip stick with oil level indicators on it inside the engine.

Just forward of the dip stick in figure 7 - 6 there is a rectangular / 4 sided plug. That is the oil drain port. Changing the oil is a matter of removing the plug and waiting until all the oil had drained and then reinstalling the plug.

Oil is added via the dip stick port. (White 2 tab cap behind the oil drain plug near the belt area)

Since I do not have your engine number I could not get your engine manual for you. The engine number is stamped on the Air Shroud of hte engine and will be in 3 parts. I believe this is your engine number but not 100 % sure: 150212-2560-B8

The parts and owners manual are on this page. ( you will need to downloand each one)

Troy bilt pony,moves so fastu cant hold it back,??????

I found that when you have the tiller at full throttle it can get away easily. Try pulling back the speed a bit and change the depth of the tines to grab a bit more but not enough to launch it. Good luck! Hope this helps you. Cheers, Michele

Engine does not continue to run

Are you laying off the choke at any point? Full choke should only be used when starting a cold engine, it should run with no choke on full throttle. If there is not enough throttle i'd first try adjusting the tiny black screw on the carb beneath your air filter while you have it idling, letting the throttle have a little bit more room. If this doesn't work and you're running it properly than you may need to make some adjustments to the H L settings for your gas/air mix. This is also done while idling mind you and only with a clean air filter.

I have a Pony 1100 series Rotiller that takes off very fast and hard to control (I'm not a small guy either)even after setting the throttle at the lower speed and adjusting to depth highth. The ground I...

The reason that it does this, is your tiller is too light. There isn't enough weight to make the tiller dig without lifting the tires up and running on the tines. MTD owns troy-bilt now, and has made them light and cheap like the rest of the MTD lines. Your best bet is to add additional weight to the front, back, and you can even add weight to the tires if you wish. The easiest way is a rock or piece of concrete on top of the handle where the handle meets the engine. I mixed up concrete and cast it onto the front guard, put some in a plastic garbage bag and hung it in that same place I described for a rock, and let it set there. Then I took off the bag, and I have a form-fitting rock that can be removed if you wish. The extra weight will keep the wheels down, and make the tiller more manageable.

Engine starts fine however it runs fast and then slow, fast, slow all the time it's running....what is that?

It is called oscillating, The carburetor may need adjusting or it could be caused by bad fuel. Manufacturer's school this year have told us, at every school, fuel over 30 days old is considered bad gas and needs to be replaced. You may even have a throttle or governor spring that needs replacing.
Good Day.

Troy bilt jr tiller

If you try to till too deep, this is what will happen. You have to start shallow and and gradually lower the depth on subsequent passes. That will even happen on my 'Horse' model if I try to go too deep too fast.

My rear tine tiller lurches out of control when I use it

Hi it sounds like you are trying too till the soil with the tiller in the fast position and probably too deep for your first pass. Really the fast position is for transporting the tiller from the field. Try putting the tiller in slow which would be the down position. Turn the throttle all the way foward, engage the tines and push your depth rod on the back down to where it is only going into the soil about four inches or even less depending on the hardnes of the soil. Even though a Troy is the best Tiller made it will try to run away with you when your trying to hog the soil all at once. Your depth setting is very important and people seem to forget the importance of adjusting it. Try these things, and remember to alway's start your tilling in the slow full throttle position. Lowering your depth a little at a time. Till you find the appropriete feed for your speed.
