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.
Poualn ppb300e trimmer only runs with the choke on. Have tried replaceing fuel lines
checked fuel cap vent, cleaned carbs twice with carb cleaner,after I had totally disassembled
it. I can see fuel in the lines and bulb. All the way to carb. When you pump the bulb 3-4 times
fuel leaks out carburetor. This all started when the return line from the carb broke (rotten) and the fuel
all ran out.I can't replace trimmer and I need to use it badly. Suggestions would be great. Thanks

I think everyone is having the same problem. replace my fuel line a month ago because it rotted and the fuel filter fell off. ran good a couple more times, but now when I start it, it idles well but dies the minute i take the choke off. I'm thinking new carborator, just looking for a second opinon. anyone? Thanks

Since the manufacture does not supply a carburetor repair kit for this unit. It is probably worth the expense and time to just purchase a new 545006017. It's not a bad price for a new one anyway
I have a poulan ppb 300e trimmer. It runs after using the bulb but will not run on its own after the gas is used up. We have replaced the carb, gasket, filter and lines. All lines are open. What is next?
My engine doesn't warm up very well and then dies under load and doesn't run fast. I've changed the spark plug, blown out the carb and it still has trouble. Do I need to replace diaphragms and gaskets on the carb or adjust something?
