Help Finding Engine Number on 1989 Snapper-Hi Vac

[Whitlock]

I just purchased a 1989 Snapper Hi-vac mower. I need to make some repairs because it doesn't run as well as the person who sold it to me claimed. The engine model placard is gone and I haven't been able to find it searching the web. I will include a couple of pics and if someone has the same mower I'd appreciate it to know the engine model number. I know it's a Briggs 3.5 hp.

Thank you!!!

There's a decal on top of the deck behind the engine. There u will find the model and serial number. The model # will give u the info on what u will need. If it's a 1989 3.5hp the s/n will start with a 9 and the model # should be 21355 or 21355P or maybe 21355PD.

The engine shroud looks older than a '89. Looks to be 1983-1987. Whatever digit the s/n starts with is the model year of the mower. If it starts with 6 it's a 1986 model.

Thanks for the reply! I had a really hard time trying to figure out the year because I didn't know the S/N number trick. I just searched each year and thought I had a 1989 because there were some youtube videos with one that looked similar. It probably doesn't help that I have it dismantled.

The model number is 21355PD and the serial number is 84211166 so its a 1988? I tried searching the snapper website for the manual using the model number and it didn't get anything so I that's why I thought I might need the engine number. Do you know a site that will let me pull up a parts guide using the model number?

I found a couple sites that have the same parts guide searching 21355PD. Snapper 21355PD Parts List and Diagram : eReplacementParts.com The part I was looking at getting was a new coil and an air filter but I don't see them. Are these just generic and will be the same no matter which model you have?

This actually looks exactly like my mower. https://www.facebook.com/Snapper/ph...19/10152573377295120/?type=1&relevant_count=1

Whitlock clearly stated that he is looking for the "ENGINE" numbers, which are stamped on the ENGINE. They are stamped into the recoil starter housing, the part in the pic by itself. They are not on a decal and don't stand out like a clown at a funeral. Usually, they are above the spark plug, but I have seen them above the muffler or on the up-facing area near the HP/Safety decal.

Jacks small engines is a good site to look for parts. If that's the exact mower u have that is pictured then yes it's a 1988 with a briggs 3.5 max engine. No problem finding parts for that. If you're unable to find the stuff u need on the site of just give them a call and tell them what u have.

And mow I assumed since it was stated that the engine model decal was missing that there was no stamped numbers on the shroud. Therefore the next place to start would be the model #.

Thank you for your help gentlemen. I was able to find the model number I was just looking in the wrong place. I got my part today and I'm just working on putting this thing back together!

 

[Snapperfreak]

Cool deal, looking forward to some pics when you're finished!

Thanks Snapperfreak, I got it all back together so I'll include a pic of it here. I've seen your pics of a snapper that you completely restored and repainted and mine isn't nearly that cool. I did spend a lot of time cleaning the engine today, but all I had was some engine cleaner, screwdriver, and towels to get in the grooves. I wish I lived close to my Dad because he has a parts washer and a sandblaster at his transmission shop.

I wanted to ask if you could take a look at the throttle assembly above the carb to see if I hooked it up correctly? It wouldn't fire up when it was back together and I'm thinking that the second butterfly valve on the carb isn't opening on the engine side because it's hooked up wrong. I was too excited to work on it and regret not taking pictures as I went. I took two pics of the throttle assembly, one is on full choke, and the other is on stop.

I'll mention that I replaced the ignition coil today and I am quite a novice at this kind of thing. I feel very accomplished getting it all back together without any bolts left over. I feel good about how I installed the new coil, but I wouldn't write it off as the problem.
