25cc weedeater gas leaf blower starts and runs on full choke only and then if I raise it upo run a little faster it will die. solution??

Ethanol gas wrecks Carburetors and Gas lines. Just for giggles see if the Stone filter in the gas tank broke off the dried out gas line.

I have attached a diagnostic sheet to help you determine what is wrong.

Needs a carb adjustment, cleaning, or possible rebuilt. Try adding a little seafoam and running at half choke for about 5 mins or longer this may clean it up nicely. also check the spark plug.

This sounds much like poor car settings ( set too lean ) you need to richen up the L and H screw on the carb, unfortunatley there will be anti tamper sleeves on the carb or a special tool reqired to adjust them, turning the screws anti clockwise will richen the mixture if you manage to remove the caps or get hold of the apropriate tool.

The raising or reving back up before it dies is a sign of fuel starvation. Check the diaphram in the carburator.

Hello i understand your frustration. Itsounds like it needs to be professionally serviced and cleaned.

you are right, check your fuel filter, fresh gas and clean your carb out,also check your exhaust screen for being plugged, also a bad fuel cap could cause this, if the cap is not venting

After you start it and are in the second stage of the choke (half choke ) let it run for awhile until it warms a bit then try openning choke and going to full throttle.

Start with the spark plug it is the easiest.

But sounds like the carbourator is dirty, Probably fouled with old gas varnish. When it is idling give it a little throttle, flip the choke on and then full throttle. If it goes full throttle and doesn't conk out, it is a fuel issue.

Good Luck

try removing the muffler and scraping out any carbon build up in the exhaust mouth of the block. if that doesnt help you will probably need to replace the carb.
