Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
Did you pull the rope while you had the starter assembly off of the machine?
Your plastic starter pawls should have little post sticking up on the top or them, these post fit into a slot in the plastic cover right above them. When the assembly is on the machine these can't come out of the slot but if you pull the rope with the assembly off of the machine these may come out of the slots and not work properly or retract when the rope is retracted. Make sure that these post are fitting back into the slot in the black plastic cap above them and then when the rope is retracted back in they will retract back into position and you can reinstall the starter assembly onto the engine.
If you can provide the model and type number from your engine I can send you pictures of what it should look like.
One thing you might try it to pull the rope out slowly as you try to reinstall the starter assembly onto the machine, sometimes this will help to line everything up and the starter will slip right into place.
While you have the starter assembly off however, you may want to manually give the flywheel a spin and see if it turns the crankshaft. Based on your prior information the flywheel could be loose and you may have sheared the flywheel key.
When you install the starter assembly back onto the machine it is not turning the flywheel? What do the starter pawls look like on the flywheel? Are they operating properly?
Unfortunately the diagram of the machine does not show a good picture of that side of the flywheel. Are you familiar with what I am talking about when I say starter pawls?
When the starter assembly in on the machine and you pull it the flywheel is not turning. You have indicated that the pulley looks good and you see no damage to the cog on it.
The pawls should be pulled in toward the center of the flywheel, they should be at 90 degrees to the flywheel.
Yes, they are or at least should be.
When looking at them, do they appear to be at 90 degrees to the flywheel?
As I said the parts diagram doesn't give a view of that side of the flywheel so it is useless. If I had a flywheel I could take a picture so that you could see it but I don't have one currently.
Can you take a picture of yours and attach it here and I will take a look at it?
That is fine, just come back to this conversation when you are ready and we can continue.
I just thought of something else that you may have happening. This starter has a secondary spring in it that may be broken or damaged. The plastic starter pulley is two part, one piece has the cog or teeth on it that engage into the flywheel, then there is this secondary spring which we call a start assist spring, then you have a second plastic pulley that actually houses the rope and rewind spring that retracts the rope when it is pulled. The start assist spring could be broken or damage which would cause the cog of the pulley to not turn or spin under a load and in turn would not turn the flywheel. Unfortunately you can't buy this spring as a separate part you have to purchase the complete starter assembly. Part number 753-08120 at a cost of around $11.50 depending on where you look.
Thank you it has been a pleasure to assist you.
