I am looking for a manual for a homelite gas string trimmer,mighty lite 26vt,where.Engine runs but spool does not turn.

50 to 1

You should wind it in the opposite direction of the head spin during operation.

Unable to download your exact model (Mighty Lite) manual. Here are the instructions for stringing a different model with hopefully the same type string head. See pages 14 & 15 of this manual. You will need Adobe Reader installed on your computer to view this.

There is a threaded cap on the spool that can get very tight, but a pair of Channel-loc pliers usually does the trick to remove the cap. Getting the string to feed consistently is a trick that I have not figured out how to do...

Once you have the string wound onto the spool, place the spool onto the shaft and pull the strings out of the slots so that the string feeds through the holes without going through the slots. Good luck...Lee

There wiil be a nut or a knob at the end of the spool where string comes out turn it left to loosen and right to tighten it. Rmove spool pull down and spool will come off foll directional arrows that shows which way the string should go put spool back on tighten screw or some you can turn with knob at end make sure it's tight before starting.

most trimmers are 50:1. or 40:1. i would use synthetic 2 cycle oil and use the 50:1 ratio. i know guys with trimmers that require 50:1, and they use synthetic at 80:1 with no problems for years. they say the engine runs cleaner. i am a part-time lawn care operator.

This is for a duel line trimmer. I hope this will help.

Cut two separate pieces of string, about 7 ft. each.

Stick the end of the line in the hole on the inside of spool.

Wind clockwise onto spool, putting the line that is closest to the ground on first.

Once you have winded this piece on, lock the last 4 inches of line through the slits on spool.

Repeat process for second piece of line, locking the last 4 inches in slot opposite the other locked in piece.

Put the spool on the trimmer, feeding the end of lines through either hole on trimmer.

Before you push the spool all the way on, pull the strings out of the locked position. Put cap on and GO CRAZY!

does it have spark? did you replace the plug?
