Will it start right back up after it shuts off

Customer reply replied 5 months ago
It does but Only if i spray the carburator with start up spray
Technician: JON, Small Engine Technician replied 5 months ago
If you have to spray it to start it back up, the issue is a clogged fuel jet and the carb will need to be cleaned internally. Very common problem.
When the machine goes to die out, spray the carb and see if it will continue to run longer

Will do - have not tried the choke open yet, but will shortly
Customer reply replied 5 months ago
Just tried it as long as i spray the engine will run.
Technician: JON, Small Engine Technician replied 5 months ago
Okay, so this means the issue is a fuel issue. Fuel not coming from carb to cylinder. I would recommend a carb cleaning. Use carb cleaner and compressed air if available. Small wire run through jets will help dislodge any debris also

Technician: JON, Small Engine Technician replied 5 months ago
Remove entire carb. Main jet goes right up the center of carb.
You can try to remove just the bowl and clean the center jet by blowing air and spraying carb cleaner into it, but full removal is best way

10mm socket will remove bolts holding air filter cover on

Here is a link to a video on how to clean the carb. may be a little different look than your carb, but same steps. they also sell these very cheap on Amzon.com and/or eBay
