Hi

Another tip, if ti is not giving a very good spark, scratch a pencil on the electrode.  As an emergency thing but a switch in the ht lead, will double the spark.  Not good to do this for long periods though!

Cheers

Dave

Hi

I have a Ride on mower and today when i got on it there was on overwhelming smell of petrol but no leak the fuel tank was full yesterday but was now empty.  I took the filter bowel off and air filter and found the filter full of petrol and noticed a small leak coming from the exhaust pipe i took the pipe off and found the engine full of petrol obviously a seal has gone but which one? and where do i get one from?

Any help is greatly appreciated

hi sounds like the carb float needlestuck open,strip carb check floats not punctured and clean out with carb or brake cleaner.fit it back together and give it a try.leave the spark plug out over night for the excess fuel to evaporate.
brute force and ignorance works everytime

Hi Slider,
Thanks for that, i overhauled the carb with new bits and this seems to have cured the problem.
Many thanks

Ignition system in small magneto engines (coil inside flywheel) consists of two circuits, low tension (LT) & high tension (HT).

LT is a coil of wire which is 'charged' by the magnet in the flywheel. The HT is a coil which is 'charged' by the collapse of the charge in the LT.

How does LT charge collapse? - The points. These open & causes the charge in the LT circuit to collapse. This induces a charge in the HT circuit.

Now that the HT coil is charged, it jumps across the spark plug so it too can discharge.

Simples....  Two circuits, each will light a torch bulb if connected with a battery. (assuming points closed). No light, no circuit - magneto coil dead - replace. (Coil slides off armature).

This is a tip which may be  useful to others. I have an old lawnmower with a pulsa jet carb. It has been playing me up for some time . Sometimes it would start first pull, then next time it wouldn't start. I found that if I put a bit of petrol down the carb it would usually start then stop, pointing to a fuel problem. I had taken the carb off previously and cleaned it all out but still wouldn't go. Today I got a new diaphram for the carb and fitted it. More importantly , it came with fitting instructions which tells you to hold the choke open by 3/8ths inch before tightening the screws to pretension the diaphram. Obviously last time I took it off I just bunged it back on and tightened it all up and the diaphram wasn't pumping up petrol. Since I've changed it , the engine has started first time every time, so I probably didn't need a new diaphram, but it was worth it to get the installation info.and cure the problem. Hope this is off interest to others with old B and S engines.
