This is a sure sign of a fuel blockage some place !! id start with fuel filter and air filter and then look closely at fuel lines for signs of collapsing when running (CAREFULLY!!!!!) then move on to cleaning and resetting carb jets
remember choke richens fuel/air mix so if it needs choke to run then it's being restricted in fuel supply

My Husky 36 did this. The oil pump drive gear was stripped and had to be replace. It's located under the flywheel/sprocket so you have to pull that. I couldn't find info on how to do that so had a local shop repair it for $70! Parts are cheap, labor is not.

hi cindilou50
check the oil filter from the oil tank,the oil line ,the worm gear and the oiler under the clutch.Clean the ways where the oil goes with compresed air.(after you fill out the oil tank)Also check the oil hose.

Mine did this when nearly brand new. You likely have a nasty jam of oil and sawdust stuck between the chain brake and the flywheel. It can be loosened by either careful prying of the case or precise shots of carb cleaner up in the housing. While you are in there look for a buildup of oil around the chain brake connection to the kickback paddle.

Most of the rancher models are easy to look at. Take the four screws off that hold the starter cover on.When off have a look to see if the pulley is ok or one of the starter dogs(pawls) is jamed . If dogs ok take the screw out of the centre of pulley and remove it ,check for spring tension. if there is just be carful to leave sring in housing. look at spring if broken or out of shape renew it and rope.check for cracks in pulley. When renewing spring and rope get correct rope length and diameter. don't over tension new spring. hop this helps

two things could be happening.......first is vapor lock......make sure you breather tube is clear and working........next is ....it could have a bad ignition coil on it.....after the coil gets hot the spark can become irratic or just not work any more.....
