Lawnmower wont start

Victa's also flood if the petcock isn't turned off after use.

In reality, if everything is correct (up to spec) needle should not leak.
Pop off pressure is first thing that comes to mind.
Pop off is more commonly associated with diaphragm carbs, but if there is a spec for it, bowl carbs should be tested as well.

My Son forgets to do it!!

I find out when the garage stinks of petrol and the floor is wet!

They can but, it shouldn't be that bad... It's a surprisingly easy fix though (for the plastic carb); simply rotate the side plate of the carb so the fuel; inlet line is higher. This effectively raises the float pivot &, therefore, the fuel cut off point. If it still leaks after that, check the needle & seat...

It's probably due for a new needle, my Parents bought the mower new in 1994 and I bought it from them - hasn't been touched apart from blades, plug & air filter.

I bought it because it's an aussie built 2 stroke ( they've been made in China for a while now), alloy chassis, large b'brg wheels - unkillable!

except for when it floods

Update:

I got the mower going again. I had to clean the carb twice. It still didn't want to start. Grrrr. I had spark and fuel. I then got the bright idea (as a last resort before giving up) of trying another spark plug.....and what do you know. It started first pull with the new plug! The old one must have become defective, even though it gave a spark.

Here is some advice for all those guys who don't try basic things first: Just do it! Check all the simple things first. Change out your plug even though it looks OK. Check that you have fuel. Check that the petcock is open. Check that there is no air getting through the side of the carb. These checks could save you the hassle of doing things that you don't have to do.

The worst thing about getting it started was that I then had to cut the grass.

Fantastic! The lesson? Assume nothing. It's been said before, that just because a plug appears to fire in open air does not mean it will work under combustion conditions.

Glad you're mowing again!
