Hello. I’m new to the forum and need some advice.
 
My son got a free Craftsman gas trimmer model C459.51212 (MTD 41ADZ20C899) that didn’t start and asked me to see if I could do something with it.
 
I noticed that the spark plug cable was defective and fixed the issue. I installed a new spark plug and filled the tank with new 40:1 gas.
 
The trimmer was difficult to start, did not run well and stalled after about 30 seconds. This occurred time after time.
 
I took the carburetor apart and noticed that the diaphragm and gaskets were not in the best of condition. I cleaned everything with carburetor cleaner and reassembled. I also cleaned the vent on the gas tank cap.
 
The trimmer still did not run smoothly and fast enough on full throttle.
 
I could not order a carburetor repair kit for this model from the repair shop but I found a very cheap kit from Walmart.ca that included a carburetor, gaskets, fuel hoses and fuel and air filters.
 
I installed the kit. Now, the trimmer starts somewhat easier but doesn’t run fast enough and stalls as soon as I release the gas throttle. I haven't done any adjustments on the low-high speed screws, really not sure how anyway.
 
Should I buy a more expensive and (possibly) better quality carburetor from the repair shop, now that I have new gaskets, fuel hoses and filters?
 
Any advice would be greatly appreciated.
 
Thank you.

I have a john deere z225 (2004).  I have had problems before with the pto, so I replaced it (2011). Recently, I replaced the engine (1 week ago) with a new B&S EX1900.  The engine runs perfectly and I have mowed with it in total approximately 1 hour.  Yesterday roughly 30 min. into mowing, the mower completely died. I started the mower again without issue and as soon as I engaged the pto, it died again. I have cleaned every connection and ran continuity tests in everything including the pto switch, ignition switch, solenoids, pto harness, and all 4 safety switches.  I traced all the wires from battery to solenoid, solenoid to harness and back again. I cant find or solve the issue. I need a little direction please!  Any ideas????

i have a tvt691 from 2001 twin carbs, popping back through cyl 1  carb, i have changed and gapped the plugs, changed and gapped the coil, readjusted the valves. all of this has slightly improved the problem but i am still popping back through carb#1 and am low on power. I have also bypassed all of the safety switches. any ideas????

During Trouble shooting
PTO replaced 3 ohms, and 12 Volts, jumps to 14V while Tring to engage, right before engine dies.
seat safety switch bypassed tied together for trouble shooting
Brake Safety switch changes state during ohm
control arms safety switches change state during ohm
PTO switch change state during ohm

Our ignition got spun inside of the housing and all the wires came loose I'm trying to locate the wiring diagram so I know which color goes where to resolder. The wires were on numbers 1,2,8,9 they are black, black white
Red and yellow-green
Thanks in advance!

I recently acquired this lawnmower from my grandpa and he said it only needs a pulll rope and it will fire right up. It’s a craftsman mower (I will attach photos) With a Honda engine. Before I go out and buy a pool rope for this exact mower, I am hoping to test the motors capability before I dump money into a pole rope and find out that I need to buy another part for it. Anyways, I have an empty B snowblower pole rope that is the same dimensions as the one that will be for the craftsman. However the only problem is that I am having trouble aligning the pole rope mechanism with the underpar with the grabbers that actually start the engine. I was wondering if this would be a quick fix or if it’s better to just pawn it off and get a different mower. Any input is helpful as I know next time nothing about small engines and specifically lawn mowers. FYI this mower has run in the past.

I am working on a buddys mower. It is a Cub Cadet zero turn, model ZT1-42, manufactured in 2019. Initally the problem was that the pto would not engage. I tested the pto switch and it was fine. I then unplugged and tested the seat switch and both control arm switches and then plugged them back up. They all tested good. We needed to move the mower and now when you pull the control arms in, the mower dies. I unplugged the control arm safety switches and it will stay running when you pull the arms in to move. It will not however start with the switches unplugged as it shouldn't.
Second problem is that now when you pull the pto switch to engage the blades the mower will die. It was not doing this before I started checking things.
I checked and rechecked everything I unplugged and everything is plugged back up good and tight. I'm really scratching my head on this. Any suggestions?

Hello everyone I had to replace the oil sump on my toro 22 recycler. I replaced the oil sump the pan gasket and the crankshaft oil seal. I made sure the timing marks lined up reinstalled the governor and the oil sump goes on easy no problem. My problem is after I mount the engine back to the mower I can't pull the pull cord. I removed the spark plug still nothing. Any ideas of what might be causing this issue. I've removed and checked everything 3 times with the same outcome.
