Sounds like you have sheared the flywheel key,and hence timing is out.also check for bent crankshaft...very obvious if it starts and vibrates like mad.

Correct timing was out key was broke

Hi I've got a Briggs and Stratton 35 classic and it's the one with the diaphragm on the tank style. It won't start and keeps flooding. I don't understand why is flooding when I've already primed it 3 times by pushing the primer bulb after that it shouldn't flood? I'm holding the brake in when pulling to start? I did it a metal pole with the blade the other day and replaced the blade, but where is the petrol coming from? If I'm not priming it?

Hi again, a bit more detail:

 

 

 

Generally 12V batteries that dip below 10.5V become too sulphated to recover & the damage ireversible.

 

 

 

For a battery capacity in A/hr of C normally the max charge rate is generally C/10 so a 35Amp/hr you'd charge at 3.5Amps. Carging at rates above C/10 can help to remove sulphite so giving it a blast with your car charger should help. You need to keep an eye on battery voltage & electrolyte level & not overcharge for too long or let it get too warm though.

 

 

 

If a battery is left uncharged then the risk of sulphation incresaes & you need to try and remove the sulphate that has plated out on the lead. The problem is that the sulphate hardens with time so the effect becomes permanent.

 

 

 

The use of a CTek charger may help as they have a de-sulphation step in the charge cycle, really its a preventative measure rather than a cure as if its been left a long time without charging its probably too late.

 

 

 

The process referred on YouTube of connecting a good battery in parrallel & then reversing the polarity of the good battery is to attempt re-condition a sulphated battery. Ive tried it with both a good battery & the output of a welder I think it was 21V with limited success but there are some fairly large currents flowing so you need to take care as it could cause explosion <insert disclaimer here>

 

 

 

If a good charge dosn't work, draw stumps & buy another battery along with a CTek 3.8 or 5.0 which can charge all types of lead acid battery.

Cheers

Mine wouldn,t start yesterday so i jump started her off my Shogun that got her going:thumbup:

How many cells has it got, 3 for 6V 6 for 12V? You'll soon fry a 6V battery with a 12V charger.

It says 12volts and reads only 2 volts at the moment and my car charger is a diesel charger up to 1900cc got it on slow charge

Lawnmower battery flat, can I use a car battery charger to charge it?
