Question about Troy Bilt Tb70ss Gas Trimmer

Troy built 4 cycle trimmer wont turn attachments -fixed?

The engin works and thr first shaft works but blower and weedtrimmer wont turn. I had similar problem for edger and made at least a temprary repair. Based on assumption that the lower (attachment) was not reaching as far inside upper coupling, I removed coupling (outer piece with red knob) and verified that the outer "pipe" was the limiting factor as to how close they connected. Then after sawing off about 1/4" of the lower attachment pipe, I moved the coupling up, drilled a new hole for the screw and it worked! My other attachments did ont have this same problem, and now they do not lock in with the push button to prevent twisting, but my string trimmer never did anyway and I don't care about the blower. Might not work for you but it did for me and it is a free fix!

Engine turns over but wont start. You can hear thr fuel pump come on. Is it electrical? Could it be battery, fuse, or loose wire?

This sounds like the crank shaft sensor is bad. The sensor sends a signal to the computer about when to fire the coils for spark.

Petrol ratio for fs38

Hi graham
I mix my oil to gas at 50:1 for my weedtrimmer at my house and it works just fine.
50:1= 2.5 oz 2 cycle oil and 1 gallon of gasoline.
Use a high quality 2-cycle engine oil.
Do not use automotive oil or 2-cycle outboard oil.
Please rate me

Trimmer runs but the head wont turn

It may be that the drive shaft is broken, or not engaged to the engine. Make sure the trimmer attachment is locked all the way onto the shaft coming from the engine. If it still doesn't work, check by seeing if any of the other attachments work when you put them on. If they do, you know the drive shaft in the trimmer attachment is probably broken.

I have a 32cc Craftsman weedtrimmer that has been giving me problems. It only starts maybe every other time, and never seems to kick into high gear when squeezing the throttle. Sometimes it will stall...

Make sure you clean or replace the air filter as well. If you replace the fuel and clean/replace the air filter and it is still giving you problems, you may need to remove, disassemble and clean the carburetor. If this turns out to be the case, reply to my solution and I can help you out.

Troy built 27cc string trimmer Model TB21 EC. What is the gas oil mix ratio?

4 cycle engines do not run on mixed fuel. Run on straight fuel. They have a spot to put oil in just like a lawn mover, and should be changed regularly. @ stroke engines run on mixed fuel.

You need to unscrew the black bumper button. I believe it is counter-clockwise. Mine was very tight and took a pair of channel lock pliers to loosen.
