Question about Troy Bilt, Tuffy, Rear - Tine Tiller, 4.0 Tecumseh Engine

2 Answers

Despite changing the sparkplug and proper choking, etc. no start

The troybuilt rototiller is a "tuffy" small one 4hp that has performed very well. It has never failed to start until last November. I changed the spark plug this week and checked oil and gas but it would not fire up.

    To goodluck 420, Thanks for the tip. I found out that the problem was the air filter, which did not seem to be dirty, in fact, was unable to be cleaned. When I got a new one and installed it, the troybuilt started right up. I had not used it that much but it was enough to need a new filter.

    Well, first things first. Do you know if you have spark at the spark plug? if not, it is probably your magneto. they sometimes rattle loose and need to be re-set. Let me know if you have spark or not and we can take it from there. Thanks.

The most likely culprit is a clogged carb - a very common problem indeed on Tecumseh motors. Pull the carb off, open it up, spray everything with cheap carb cleaner (especially the bottom "bolt" that hold the float cover making sure it sprays out of at least two sides as that "bolt" is also the jet), make sure everthing lines back up as you pulled it apart and now try to start it up again! Bet it works, I see it all the time on small engines left with small amounts of gas in the system. Good luck, and I hope that gets ya runnin!

Wheels 0n troybilt rototiller won't turn


Many Troybuilt Tillers have Pins on the Wheels and axle. Like troybuilt Bronco for instance. If you want the wheel to turn you need to set that pin so it goes through the rim and through the axle.

I have trouble starting my troybuilt 0 turn 42' ride mower when i first st art it for the day. i have to spray gas into the carb to start.it,s only a year old


Does the battery need replacing ? The voltage should be above 12.8V for easy starting, Alternator should be charging at about 14 volts.
Check the choke plate is operating properly.
Check air filter is clean.

I have a rototiller that will only run with choke on. changed sparkplug and fuel. blew out lines with compressor still will not run outside of full choke


If it only runs with the choke on it isn't getting enough fuel. You will probably have to disassemble the carb, and clean well. Engines and carbs vary, but the main fuel passage from either the tank or fuel bowl, just be clean. Sometimes just blowing out won't do. Might be worth buying a carb kit, and clean it throughly. Sears web site will have a great parts breakdown if you enter the model number. See link: www.searspartsdirect.com

MY MOTORCYCLE STARTS UP WITH CHOKE, BUT THEN TURNS OFF.


You have to just tune up your air fuel combution chamber with a proper setting as this happens when this setting has been changed. Just go to a proper service center and do a service of your bike and ask them to check setting of it. According to me the optimized ratio to air is to fuel (AIR:FUEL) should be (9:1) for better performance of bike. But it is better to ask service center technician as it veries according to surround environment, fuel inatake by vehical, etc.....

Troybuilt rototiller


Most of them have a pin to lock the wheel to the axle... Check the center hub of the wheel and see if you can find some kind of hole that a pin would go in to lock axle to the wheel...
