If any member would like any information on Briggs and Stratton engines I have a Service Manual for Out of Production Engines 1919 – 1981 all is in pdf format

  I would love a copy having issues with throttle cable on our little Merry Tiller

Hello,

I've an odd problem with my Briggs & Stratton engine.  It recently ground to a halt and while fiddling around with it found an odd problem.  The engine will start and run without the spark plug lead on, but when I plug it in nothing happens - it's dead.  I don't know a huge amount about engines but know that this is a little strange. 

Here's a video clip r5iTajoInKs

Any ideas ?

have you by any chance put diesel fuel in it?

Nope....  but I've had it to bits again and quite sure it's a problem with the lead or magneto so will look at replacing that

Tie the plug lead away from the top of the plug and if it starts I would be shocked.

The magneto coil sometimes need re adjusting as they work loose and need to bee loosened off and re we putting a business card between the flyweel and the magneto and let the magnetic force pull it tight up to the flyweel and re tighten

Hope someone can help with this strange one: firstly I know it should go back to the dealer, as I bought it new this Spring,  but it means half a day off work to get it there and half a day to get it back. This relates to a Maspro mower with B and S engine. It reliably starts first pull from cold with choke as you'd expect. It also restarts while warm after the short time it takes to empty the catcher, with no choke necessary. However if I leave it for a few minutes it just won't start with or without choke. I sometimes get it to fire a little bit but it doesn't pick up and I know then that the only thing to do is leave it for an hour then do the normal choke start whereupon it starts first pull again. This would be frustrating enough if it was happening on my own lawn but it occurs when I do customers lawns which costs me time and also doesn't look very professional. I have asked the dealer about it but he couldn't understand what it might be.

Modern top-valve Engine?
You need to Clean the carburetor and the petrol bowl/cup... it is filled with dirt and grass...

Older models have this problem with the petroltank.
...kind of surpriced about your dealers reply... this is typical for the B&S lawnmower Engines...

[Steveharford]

Well I explained the problem to another dealer who immediately recognized the problem as a defective plug cap. Something to do with the suppressor within it I think. Anyway he sold me a simple rubber covered cap to replace the dodgy metal one and I have had no trouble since. Why the manufacturer continues to use these problematic caps is a mystery to me.

Before I start fiddling and making things worse , I'd thought I'd ask for some advice. I've just bought a rotavator with a B&S 3hp I/C engine. It's starts ok and runs ok until it is put under heavier load such as digging quite deeply when it stalls. There are two controls on it, one is choke and the other seems to be an adjustable throttle, but doesn't run very well at anything above the default low setting. Any ideas? Does it just need a mixture adjustment? I'll check the plug this afternoon for sootyness.

Edit: I've just found that the small engines website is back up, so will try the advice on there unless anyone knows the problem.

cheers

Don't know if this helps: B&S manuals galore here:
