Lawnmower first start up advice

[ipbr21054]

Hi,
I am going to start mowing again at the end of this month so today i decided to start the mower for the first time since Last October.

Ive put some new fresh fuel in with the small amount i couldnt get out in October & second pull it started.
Needed choke but started.
After say 3 minutes it stalled,i started it startight away and it runs.
Revs seem a little loud but i havent touched / changed anything since its last use.
With the throttle lever set say 1/2 way between tortoise /hare it runs fine for a while but it does die/stall after a while without just running until the fuel in the tank is empty.

can you advise what this is or what i should be now doing to get it ready for its new season

Its always a good move to start off with fresh oil and a blade sharpen.
Give it a new spark plug, check the air filter and if it still doesn't behave, post back with the make.

New carb,New plug,Air filter,Blade & oil was changed last year in October
There was minimal old fuel left so soon the tank should be empty

OK, I'll need to know if the machine has an OHV or side valve engine, if it still misbehaves.

how will i know that

 

[Burnerman]

On the side valve motor, the carburettor actually sits and is screwed into the tank. On the OHV the carb sits alone, float chamber is visible.
A picture or two of the engine would help!

I'm guessing it has a little primer/plunger thing ?

after it has run a little while and starts to die, give the plunger a press, if this gets it going again for a little while. Then my guess is dirty carberator.

don't know what this obsession is with changing spark plugs, they last for years, my lawn mower is 30+ years and still on the original. Unless the electrodes on the end are burn't to buggery then they don't need changing.

Well its tipping down but the carb is bolted to the side of the engine.
I remember the float bowl has a 10mm bolt going up the middle to hold it to the carb & also there is a bolt in the side of it to drain the fuel down.

Now trying to think about the primer bulb or wait for rain to stop

Petrol tank is mounted separate to carb / engine

 

[Burnerman]

It sounds like an OHV engine, with a red primer bulb facing forwards?

Clean the carb.

 

[ipbr21054]

There is no primer bulb.
Started this morning & didnt cut out,revs a little high but maybe it will clean through

These engines often have the Briggs auto choke system......basically a device that takes heat from the exhaust and controls a choke flap.
