What causes a Craftsman CMXGRAM1130035 engine to idle rough?
A rough idle in your Craftsman Lawn Mower engine can be caused by a spark plug that is fouled, faulty, or has a gap that is too wide; replace the spark plug and set the correct gap. Another potential cause is a dirty air cleaner; replace the air cleaner element and/or clean the pre-cleaner.
Why does my Craftsman CMXGRAM1130035 Lawn Mower have an uneven cut?
An uneven cut with your Craftsman Lawn Mower can be due to several reasons. The deck might not be leveled properly, so perform a side-to-side deck adjustment.

What to do if my Craftsman CMXGRAM1130035 engine runs erratically?
If your Craftsman Lawn Mower engine is running erratically, first, ensure the choke is deactivated. Check that the spark plug wires are securely connected. A blocked fuel line or stale fuel could also be the problem; replace the fuel line, fill the tank with fresh gasoline, and replace the fuel filter.

Water or dirt in the fuel system can cause issues; drain the fuel tank and refill it with clean, fresh gasoline. Lastly, a dirty air cleaner can cause this issue, so replace the air cleaner paper element or clean the foam pre-cleaner if your mower has one.

How to improve mulching with my Craftsman CMXGRAM1130035?
If your Craftsman Lawn Mower isn't mulching grass effectively, make sure the engine speed isn't too low by placing the throttle in the FAST position. Avoid mulching when the grass is wet.

A dull blade can also cause poor mulching, so sharpen or replace the blade.

A blocked fuel line or faulty spark plug could also be the culprit; replace the fuel line and filter, or clean/replace the spark plug.
