Push mower will not start....

[Tikal]

It has spark but their seems to be something wrong with the gas system,
I cleaned the carb and it still would not start, cleaned the gas tank and it still refused to start. What is the problem?

Please help!!

Take wing nut & top off the air cleaner, spray some starting fluid into it and see if it then tries to start... :smile:KennyV

That is one really cool old mower -- so please don't give up on it. :thumbsup:

If you crank it several times and remove the plug, the plug should be wet with fuel -- if the gas is making it into the cylinder -- is it?

When you're trying to start it, does is fire at all?

Good luck and please keep up posted on this fine machine. It looks like it's mid-1960s -- what do you know about it?

Thanks!

I will try that, thanks! Yes this mower is really cool! You can push on both sides, i think it looks like a steam engine. Our elderly neighbor has lots of old ones and he gave this one to me.

I changed the spark plug and now stuff is coming out of the muffler, and yes the spark plug was wet. It seemed to try to start but it still could not, and that was with the air filter out.
The air filter has fishing string in it, I guess the fishing string acted
like an air filter awhile ago.

Does your neighbor have any old (pre-1980) Lawn-Boy two-strokes in his collection? If you're interested in fixing old mowers those are some of the best ever made -- well worth your time because they're awesome once they're running right.

Is fuel (unburned) coming out of the muffler? When you say it "tries to start" do you mean that it fires somewhat but never really starts?

Have you looked at the main jet adjustment on the carb? Did you clean that when you cleaned the carb?

Have you looked at the points? You might have to remove the flywheel (may be very difficult if it hasn't been off in 30 years ) to get to them.

I do not know but I will check.
If he does, how much should I pay if it is in fair condition?

Yes it fires every once in awhile.
The spark definitely works, my brother found out the hard way(metal conducts electricity! Never new that but that was only once, the spark might only be working every once in awhile.
Where is the main jet? I took the whole carb off and washed it.
