trying to figure out what engine I have on this 5751. Has the wrong fan shroud for an "N" but everything else seems right! Take a shot.

I would say its a later model 8, the early model 8 was round top. If it is, it's would be 2 1/2 hp.

Looks to me like it could also be a model 6. The model 6 would be 2 hp and have a 2" bore. The bore for the model 8 would be 2 1/4".

The model 6 is a round top, the model 8 came in both a round top and a square top. I have a round top 8 on my Super Power. The model 6 I believe was 1.6 hp, the early round top 8 was 2 1/4 hp, and the later square top 8 was 2 1/2 hp. The DB 560 Super Power came with either depending on when it was built.

The model 6 is a round top,

All of them?

Could these manuals be wrong?

6, 6F, 6FB, 6FBC, 6FBP, 6R4D, 6R-6

And from your own website:

Definitely a model 8. The model 8 is the only Briggs that had that oil pan design, with a square top. There is a model 8 for sale on ebay right now, but its missing the carb, and the don't know its a model 8. Go to ebay, and type in "1hp Briggs & Stratton engine". Here is a pic.

Here is my Model 8 Round top. The SN# says it was built in 1952.

The model 6 used the same oil pan and had a square top.

Thanks, I stand corrected. All the model 6 Briggs I've seen were round top, so I guess the only way he can know for sure is to measure bore, and stroke.

Actually its just the bore thats different. 2.00 or 2.25

Well that was fun. Not a roller coaster on earth that can beat that ride!! I love you guys and this forum. Until I get the head off and measure the bore I'm going with the late "6" with a square top. That way I can still hope that the engine could be the original. The "8" would have to be a repower I would think(break my heart) A big double thanks to all of you for getting in on this and we"ll see where it goes from here. Skip
