2416H Simplicity Lawn Mower - Instructions

Clean engine with a Gunk type product. Remove valve cover. Loosen bolts and remove old cylinder head. One bolt is located inside valve cover area. Remove old gasket and inspect and clean that surface. Attach new head with new gasket using existing bolts. Torque to 18'#s with a cross type pattern. Attach new rocker arms and push rods. Set valve clearance to .004 - .006. Attach valve cover with gasket. Check oil level. Start and let it warm up. Let cool remove cover then check valve clearance again. Replace cover.

I removed the fan shroud, the carb/manifold as an assembly,turned the carb upside down and removed the fuel bowl. I replaced only one jet. Not until this moment did I discover their were two jets in this nikki carb. I now have a second jet ordered and will install it Friday,hopefully. These jets are two different part numbers as one is a left jet and the other is a right one. Be careful when opening the fuel bowl as these jets are held in their bores by small O-rings, and nothing else. The brigg's and Stratton part numbers are 791501 for the left jet and 791502 for the right.

Look on YouTube for video's on how to replace a Briggs governor. There are several there. My favorite, with best explanation, is, "Easily Replace Briggs Governor Gear (V-Twin Intek Engine) with Taryl". https://www.youtube.com/watch?v=wn3eanGxSEA&t=152s.

Taryl (probably not his real name) does a very good job of showing step-by-step the whole procedure, along with some additional hints/tricks/techniques of value.

Not including oil and filter, I spent less than $50 for a new governor, gasket, and drive shaft seal. That's all that is really necessary to replace is those three parts. That is, unless pieces of the old governor tore up a gear, valve, or something else. Inspect everything! {I was lucky and only the governor was destroyed}

One word of note. Be sure to clean out all of the debris from the blown governor. Be sure to remove the spark plugs and carefully rotate the drive shaft while looking for nooks-and-crannies where debris can hide. I tried to use a magnet to help, but it didn't help much, even though the block is aluminum.

Good luck.

I went to Troy-Bilt first first for the part-nothing, then B&S engine, still no help surfing their websites for this part. Again, no help. Before giving up completely I thought about all the parts I have bought from PartSelect for washers and such. Typed in "Fan-Flywheel" B&S. First thing that popped up was a picture of this part. All my searching on Troy-Bilt mower site and B&S site for over two hours with no results, and then I go to PartSelect and without my model number or anything else, they had it and even displayed my model number and sent it right away, popped it in and the mower is working fine as ever. No matter what you need, I say save yourself a lot of time and just go here first. I'm a loyal member of PartSelect for over six years!!!

First I opened the top of the mower to expose the housing cover. Secondly I removed the four housing bolts to remove the housing cover from the mower. Next I removed the tube breather and installed the new tube breather and replaced the housing cover with the four bolts previously removed and closed the top of the mower. I filled the mower with gas to check for leaks which weren't any leaks. I proceeded to mow the lawn with ease.
