Have a weedeater lawnmower HD12538j which changes gear speed fine when the engine is not running but when it is started up it is very hard to change gear speed or will not change at all. I have to put it in the speed I want to run in then start the engine. The clutch seems to work fine.

SOURCE: weedeater or trimmer

sounds like the carb is still not right or the unit is low on compression - you need 90 lbs min

SOURCE: Engine dies when excelerating - more gas

check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes. if that doesn't work have the carb repaired at a service center or replaced.

SOURCE: My stihl weedeater starts and idles fine but does not get power.

I have a Stihl FS 45 and have had problems with it running for a short time then cutting out. The problem is like to be either- the filter attached to end end of the fuel pick hose that goes down into the fuel tank is blocked or- there is a crack or split in the corrugated section of the fuel pick up hose between the fuel tank and the carburettor. If such a crack or split exists it will cause air to be sucked in with the fuel upsetting the fuel/air ratio. A new hose not adjustment is the only cure

SOURCE: Stihl weedeater starts but won't run at high speed

This sounds like a timing problem.
It is too far retarded, and needs advancing a couple of thou.
There you go:)

Seasonal equipment storage.

Every winter when the grass stops growing and we walk away from our lawnmowers, weedeaters, edgers, blowers, ect. we tend to complain when they will not start when it's time to start using them again. A simple little tip that will help this problem is to treat your fuel through out the season. Your only other option would be to turn the fuel off and run the fuel out of the carburator until the engine dies. Then drain the fuel out of the tank. When it comes time to use your equipment again, it will start because it has fresh fuel.......and you won't be complaining. This would also be a good time to change your oil, grease your unit, clean/change your air filters, fuel filters, ect. sharpen or change your blades, replace worn belts, ect. When it comes time to use them again, you will be glad you did.

I think you have an engine speed sensor fault. its not reading the engine speed or the motion speed. needs these two to change speed and ( gear). one is connected to the abs unit and the other is on the engine. usually if they both go its down to the gear box ecu. you can check if you have it on a ecu reader. will have fault codes or not be read at all.

Automatic gear fault

slipping is clutch ?? why would it be electronics. un less its an auto box. if it auto box can be a lot of things. most common is the breathe hose blocked up. if it runs fine until it gets hot then it can be this. if it is like it all the time it can be the speed sensor not reading the rev speed to change gear. if it is doing it slowly taking time to change gears its is not reading the engine speed or the abs speed sensor you would no if it was this as you would have a jumping speedo speed. to get the best solution you need to have the engine and auto box read.

take all wheels off the ground use jack stand,start engine up and put car in drive and let it run for about 5 mins, with wheel off the ground it should shift gears better, if it do you to change your transmission filter and oil, VERY IMPORTANT TO CHANGE OIL WHILE IT IS HOT! check oil to make sure no metal is in oil or heavy shavings, if shavings or metal is present you need new tranny,measure the amount of oil you take out put same amount back in, i really dont think you got a speed sensor problem you might have too much milage on your yukon, hay mon sure you service your yukon on time or else ford will excort you home, good luck mon and big up u self

Lawnmower will start but will not stay on

I had the same problem, what you need to do is adjust your throttle. To do that you there is a switch right in front of the filter. If you are looking right at it pull it all the way to left. If this dosen't work then check the springs that are connected to that switch they have a bad habit of coming loose. I had to replace all of my springs. Hope that helps.
