Older model Weedwacker Trimmer/Edger with flip switch on shaft that converts trimmer to edger. No serial/model number/manual. Need to order the metal guide (curved, v-shaped) that fit under shield. Help!

have you read your operators manual.? They generally just unclip and pull out.

You haven't mentioned the make and model in your question. It may help people answering if you can tell them the exact machine you are referring too. :)

On the WEB, maybe they can help:

When looking at the head, you will see to two gray rectangle pieces. Press them both at the same time between your thumb and forefinger and then pull. It should come unlatched and reveal the line spool on the inside

On the shaft is the sticker with the model # & the sn

I have a Ryobi Model RY28040 straight shaft line trimmer. In my case I replaced the complete String Head Assembly that includes the String Head Housing, Spring, and Spool and the string still did not advance. I then discovered that the bolt in the Spool Retainer cap (the red cap that attaches the spool to the shaft) was fused and not moving. The bolt needs to be loose inside the cap in order to allow the spool to move in and out by the spring. I loosened the bolt and fastened the spool back onto the shaft. Fired it up and bumped it a few times and the line began to advance. Turns out I probably only needed to replace the Spool Retainer rather than the String Head Assembly.

Ryobi Trimmers unscrew halfway down the shaft (so it fits in the box). If this gets loose, the trimmer will stop working. Simply tighten the connection between the upper and lower half.

One of 2 things...drive cable broken or clutch spring broken

the wiring maybe disconnected, either at the switch or down near the head of the trimmer

To get a manual for a Troy-Bilt product, you need the model number. For some units, the serial number is also needed to obtain the correct version of the manual. The needed information is on the edger itself, in a spot that usually will not get damaged when you are using the machine. For wheeled edgers, look at the rear of the deck when you are in the operator's position. The string trimmer/edger models similarly have the plaque with the model and serial number in a spot that won't get damaged.

Start here: http://www.troybilt.com/webapp/wcs/stores/servlet/HelpView?storeId=10001&catalogId=14102&langId=-1 . Fill in the model and serial numbers and then click Find Manual.

If you add a comment with the model number, I will be glad to look up the exact location of the manual for you. This would be a link to a PDF.

I hope this helps.
