Need to know where to find the model # of the engine to procure the muffler & gas cap for this Honda Overhead Cam self propelled lawnmower.

If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you!

Carburetor Assy. - Wyb 16C - 16100-Z0Z-815

Repair Difficulty:
Easy
Time Spent Repairing:
15-30 minutes
Tools Used:
Pliers, Socket set, Allen wrench
Throttle arm broke off of the carburetor when I accidentally dropped the weed eater. So I had to replace the carburetor.
1. Removed plastic engine cover and air filter box ( Allen wrench is required) .
2. Removed fuel lines ( supply and return) from carburetor connections
3. Removed carburetor ( two nuts)
4. Removed old gasket and replaced with new gasket.
5. Removed old oring off of old carburetor intake .
6. Put old oring ( probably would have gotten a new one if I had known about it ) on new carburetor.
7. Reverse first three steps .
Forgot to mention throttle cable removal from carburetor and reinstall. Very simple .

Primed and started on third pull . I also bought new gas tank grommet, fuel lines and filter but didn’t need to replace at this time . Sometimes the fuel lines are brittle so better safe than sorry.
