How to Test a Small Engine for Spark
If your small engine isn't starting, you'll need to diagnose many issues including the spark plug. This video walks you through the steps of how to test for a spark using a spark tester.
Starter spring disengaged from starter and unwound
Service on the starter on this model Poulan requires removing the handle, front housing and clutch as well as the rear housing, motor and gas tank. To remove the clutch, I had to mount the motor in a vise and use a hammer and block to knock it loose.
Reassembly was easy, although placing the spring down in the housing and getting the end secured without letting the spring unwind takes care. Then place the starter in position and rewind it.
All done, I refueled the tank, the motor started on the 3rd pull, and the starter rope rewound properly.
I have a Poulan PPB 250E, only one year old. Bought a new carb for it, forgot how fuel hoses route, can anyone help.
Only way to keep engine running is with full choke and feather throttle. Replaced fuel hose and pick-up filter.
I have a Poulan250E, I recently installed a new carb on it. I cannot keep it running without the choke being on all the time. Also, I have replaced the two fuel hoses and filter in the tank. What is the proper routing of the fuel hoses?
I have the same problem with my Poulan PPB250E trimmer . What did you do to get yours to run right?

If you can NOT run your 2 stroke yard tool without the choke being on, then the engine is "going off lean." That means it is sucking in EXTRA air somewhere or the carburetor Mixture screws need adjusting. The carburetors nowadays are typically set very lean by the manufacturer to conform to recent EPA C A R B III emission regulations. I know this thread is over 4 years old but this information is pertinent here now.
