The start pull cord has no tension on it, I can't find a reset control, is there an easy way of fixing this?

When fitting any pull start spring, you must first pre wind the spring. Once the spring has been at least 1/2 way wound up or tensioned, wrap the pull rope around the spool. When you assemble it and pull the cord, the spring should wind up further to its fully wound position and now retract as normal. If you don't prewind the spring, there will be little or no tension to rewind the rope.

You take the top of the motor off with the starter, then rewind the spring,then is a good idea to replace the rope with a new one they sell rope at a lawnmower store, get 5 feet or more if the rope is up on the handle, take a piece of rope with you to get the correct size.

your cord is too long is why its binding up ,,,on the tee hand where you put your hand on to pull,,,,take a screw driver and push up the tied knot out and away from the tee handle,,,,take and make another knot about 8 inches and pull the cord back into the tee handle then try it again. Most have a long rope, cord etc for maximum pull,,sometimes they go overboard on the length and it binds up on the rewind of the recoil system

The cord should be removed from the spool entirely, then wind the spool spring CCW for a number of turns making sure the spool can be turned for about 6 turns more (during start). Wedge the spool so that it can't unwind the spring again. If the old cord was about worn out, replace it with fresh. Melt the cord end somewhat so that the knot won't pull out, then tie an overhand knot in the cord end. Feed it into the inner retainer on the spool, then thread the cord around the spool 5 or 6 times in a CCW direction. Once wound, feed the loose end out of the cord port, slide the pull handle on, melt the cord end, and tie an overhand knot on it. Stuff the knot into the handle and release the wedge from the spool so that spring tension pulls the cord tight. Pull the cord out several times to make sure nothing interferes with cord and mechanism, then install on the saw and check the start operation. The spring should never bind-up when the cord is fully extended. Hope this helps!

hi you need to wind the spring to put tension on it depending on the type of recoil starter it is faily easy or dam near impossible "nothin is impossible "
take the compleate starter assembly off the motor and undo the rope from the starter / fit a new piece of rope 12 ins longer than origonal turn the center piece anti clockwise 2 turns ,this will wind the spring up wind the new rope on to the pulley put the handle on so you can feel it pull back and knot it so it has tension on it hpoe that helps merlin v12

Soundas like the rewind spring is broken. Remove the top housing and see if you can reset the spring by removing the cord, hook up the broken end, rewind the spring with a screw driver...lock it in the tension position and then reinstall the cord.

Replacing the spring on this tiller can be tough. You have to get the tension spring set into the stop and partially wind the tension (by turning the cord pulley) and THEN attach the cord before completing winding the tension spring. It took me about an hour to figure out how much preset of tension was needed before I was able to get it to work. You have to partially preset tension because starting from zero will not fully rewind the cord.

This sounds like the timing is off. Remove the spark plug and pull the cord to see if there is less tension. If there is less tension then you know that the pull cord is fine. Do a compression check on the cylinder, it should be around 100psi. Remove the valve cover and check to see if valves are moving when your pulling the cord. The valves could have came off the rockers.

Good job on the cord replacement. Most people take the cover off the spring and then find out it is nearly impossible to get the spring tension set. I have personally repaired dozens of these cords that have been messed up by owners that did that.
If anyone has this problem, just do what this post says...remove the assembly and turn the pulley until you can get to the part of the cord that is broken...grab the end that is broken after you get it out of the opening with a vise grip and pull the cord out fully and lock the recoil spring with a vise or vise grip (but don't crush it)...then replace the cord and hold the end of the cord pull fully extended and remove the lock and allow the spring to recoil...and reinstall the assembly.
Simple, but THINK before you take the housing apart. It is REALLY TOUGH to reset spring tension properly.

It seems you do not have enough spring tension. Remove the starter housing and grab the slack rope and wind the pulley two or three times in the tension direction until the slack gets pulled into the pulley by the spring. Hope this helps. Donnyb60
