Flymo L38 two stroke engine hunting

Hello All,

Sorry, not really a proper old mower but some one might have some ideas.  

I bought this L38 Flymo about 25-30 years ago to do banks when I was doing mowing contracting and got it out the other day to use it or get rid of it and gave it a good clean and tried to start it.  I got it started but it won't run without the choke half on no matter where I set the mixture screw and as soon as it starts running on the half choke setting, it starts to hunt (that's what I call it when the revs go up and down). It has no throttle lever, just set at full throttle.

I have cleaned the carb out several times and cleaned the fuel tank, checked the air filter etc.  It appears to have a good spark although I don't have a new plug for it, I have given the old one a good clean.  I feel it is a mixture issue but don't know what to do about it now.  I don't really want to throw it away but am close to giving up on it.

The carburettor is a conventional one, not a diaphragm one.

Thank you for taking the time to look at this.

Sorry, when I say "do banks"

Sorry, when I say "do banks" it sounds like I was using it instead of a sawn off shotgun!

What I meant to say, of course, was I got it to mow grass banks.

It made me chuckle when I read it back though. 

Richard.

First thing, what engine,

First thing, what engine,  and does it have a diaphragm or bowl carburettor? 

An image or two may assist.
