Having trouble getting my LawnBoy Briggs and Stratton, 6.50 with Ready Start to start.


I tuned it up- replaced the plug, oil, filter, (it was emptied of gas after the last use) I half filled with fresh gas.


Its not turning over. I cant find the primer. Looks like it should be here,


Any ideas would be greatly appreciated.

Your engine has a temperature controlled automatic choke, no manual choke or primer. Google: B&S manuals, enter engine number 126t02-3212-b1, operators manual & parts list. Engine cold adjust valves to specs. page 9.

Try some starting fluid, if it runs for a few seconds then its a fuel issue, if it does not pop off then you have a spark issue. Draining fuel can cause it to gum up when the remaining gas evaporates.

Serial number is 0811045969879


I dont see any other numbers on it.

Ready start doesn't have a primer.

That is what I was beginning to think.

Instead it has a fuse I think. Is that correct? If so, where can I find that?

Ok..its not an electric stat, and does not have a primer....


Thanks mechanic mark, great info! Ill go through it and give the mower another start after the snow melts...getting hit tonight

Mark has added info to his post.

If it's electric start then there's a fuse.
So what exactly is the problem, you said not starting then not turning over, then asking about primer? This will help all those trying to help.

I am looking for a schematic or picture of where the fuse is located and what type of fuse it is.

I used some ether to get it going and it started for a couple of seconds. I am not even sure there is a fuse at this point.

Going to clean up the carburetor tomorrow.

Any help with any of these topics will be greatly appreciated.

clean the carb 9 out of 10 times that is the issue but of course check for spark first and don't look for the fuse that is not there

The model number is 10641.


I have not used the mower this year. I

Yesterday I took out the carburetor and cleaned it with carb cleaner. I gave it some time to sit and it started on the first pull but died after a few seconds. After that it did not start.

I thought it was an electrical problem. I pulled the plug and with it connected to the wire harness I pulled the cord, no spark.

Next I cleaned the ignition coil with air and some carburetor cleaner. I put the mower back together and I am not getting any spark from the plug nor am I getting the mower to start at all.

Any ideas? Please feel free to link any old threats or schematics to help me along the way.

I just took out the ignition switch and tested it with a multi meter. It gave me a few readings, some of just 1 and a few about 3-5. I cleaned it off a bit and can see a lot of copper. I put it back in and no go.

Hi Mozz,

I think your model is one of the newer versions from 2009-2010

So I just have to ask, I am certain it has a safety handle that has an engine clutch/ignition ground to stop the blade quickly as possible when the operator leaves the handle area.

When you are checking the spark, do you have that handle held in the run position?

I just find it terribly hard to be able to run the mower and hold all the safety features at the same time. The lawyers and congress has it so you can't pull the starter cord and be anywhere near the engine, let alone check the spark by yourself. It is set up like a dead man switch, so If you are not by the handle well at least a good 5 feet from the blade, the thing is designed not to run.

I would not dare to recommend that anyone try to tie the handle shut with a strip of cloth or light rope as I may get it trouble with the mower police or bring about a lawsuit. That and of course I would not want anyone to get hurt.

That is what I wouldn't do...

You got it to pop and run for a short time, so you had something. I just bought a new carburetor for my 10685 on ebay for about $20 The parts to rebuild my carb were that much to do it myself. My 10685 has a different motor on it. (Techumseh)

I just had another thought too, again safety standards predicate that there are switches that will not allow ignition if the bag or guard are not installed on my model.

Looks like on mine, there is a magnetic safety switch that will cut ignition if either the bag or the plug (there is a bulky plug like fill piece that fills the grass to bag chute when you are not using the bag option) and if the plug latch is not fully engaged, it will not allow the ignition to spark.

Just another thing to check before I started to throw parts at it.

Find and give a quick read / review of the owners manual if you have not read it in a few years. You may just find a little nugget like that in the book.
If you no longer have the owners manual handy, a google search should eventually lead you to the document to download and read online.

It has been raining and soggy here for a few days, so no lawn is getting cut this week..

Please,
If you fix your fault or find something out, find a link, realized that you missed something obvious...

The next guy may be in the same situation as your are (were) and your discovery and report of how you solved your dilemma may help the next guy in the middle of the night when everyone is asleep or not answering questions on the board.

I feel it is only a fair shake to give back information when you ask for help. Don't be that guy... Nobody should want to be that guy.
