won't start

The engine will turn over easy without the plug because you are not building up pressure in the cylinder because the air escapes through the plug hole. With the plug in it will take more current to turn the motor over because you are building compression. Try jumping your battery with your car and see if the engine turns over faster.:biggrin:

Now we are jumping from too much compression to electrical what next. Maybe take a compression test, test your battery, if that is OK see how much of a voltage drop you have at the starter or test how much of a amperage draw you have. It is getting beyond just guessing at things and start doing some testing which should have been done in the frist place.
 
I am going to go with a week starter. I have gone threw the same thing and ended up being the starter

What in the world is a weak starter. I surly would want to make some test before spending money on a new starter. Why is the starter weak? Low voltage to the starter, voltage test? bad cables or starter solenoid? battery? bushings worn inside starter, amperage draw test Mowerguy said not electrical so I would add a compression test or amperage draw on top of it all. That will tell you if you have too much compression. Stop all the guessing I have found that the guessing game can cost you money with unneeded parts.
 
talked to a local lawn mower shop yesterday. just said too much oil in the head which wont allow the spark to ignite. thats what i thought was the problem from the beggining. he said spray some carb cleaner in the carb and in the head

I agree with him to a point. but adding more fluid into the engine isn't going to help the matter. Maybe a new spark plug and a very little starting fluid?
 
it has a new spark plug. and his solution didnt fix my problem. it will do one complete cycle. but when it builds compression on the second cycle it completely stops it. so maybe one of the valves is sticking not allowimg it to relieve compression during start up. i think im gonna break down and take it to someone with a little more knowledge.
 
Is it flooding with gas?When you pull the plug out,is it wet?Sounds like it can't overcome volume of something in cylinder.:confused:
 
that sounds like that might be the case. when i pull the plug out it has something on it but i dont know if it is gas or oil
