Carburetor Replacement for 33M777 33M677 331977 331877 331777 31Q677 33M97 Carb

Great item.... Works great... a breeze to install... fantastic price.... perfect replacement and fitment.... no adjustments necessary.....

Great working replacement on 2003 craftsman lt2000 with briggs and stratton 20hp, electrical connector even works great. No adjustments needed at all. Best value replacement I could find.

This replaced my Nikki carburator on my Craftsman yts3000 42" ride on mower. For the money, I tried it out rather than rebuilding the original. It was worth the purchase! I was back to mowing in no time and will probably buy another for a backup. It's been 6 mows since I replaced it and still running great...

Craftsman LT200 riding mower started up fine after sitting through the Winter, but stalled when I engaged the blades. I then could not start it again.The fuel cutoff solenoid was not stuck, and spraying starting fluid into the air intake allowed the engine to catch for a bit before sputtering out. So it had spark and compression. I changed the fuel line and fuel filter, which didn't help, so I concluded the original Nikki carburetor was clogged.I chose this replacement because of the great reviews. It installed easily on the 20 HP single cylinder Briggs and Stratton 331777-1372-B2 engine. The riding mower then started up just fine, and continued to run fine with the blades engaged. I did not have to make any adjustments for the throttle, choke, idle or fuel/air mixture.Note: before replacing the carburetor I noticed the choke was not fully closed when the throttle lever was in the choke position, so I had to un-clamp the throttle cable and reset it. But that was prior to replacing the carburetor. Just mentioning it because this is a common issue making these mowers harder to start than they need to be.I ordered a rebuild kit for the Nikki carburetor -- I'll get it ready in case this new carburetor ever gets clogged. But the mower starts and runs great, and I don't anticipate any issues.

Works great, no adjustments needed. Have run it several hours since installed with no issues.

Perfect fit, very little adjustment needed to the carburetor. Cheaper, faster and more reliable than a rebuild.

Good buy. Worked for our lawn mower.

Seemed to be identical to the original. Easy swap out and solved all my surging and rough running issues that carb cleaner could not.
