Identify these motors !

So you wouldn't recommend removing the welch plugs

I'm not against it, I just haven't found it necessary. Only if carb looks really fouled up or If you know for a fact that something other than gasoline entered it.

Just soak in carb dip, wash off, and blow out the passages with compressed air ?

Yes, and I would recommend using an ultrasonic cleaner if you have access to one. Works wonders.

i'd like one too but my golfing partners wouldn't be very pleased with it

if its a sears and its 80s or older chances are its a techumpseh newer is a brigs. Those bothe apear to be techumpsees judging by the carbs. most briggs that old had a 2 piece carb. sears started using techumpseh then briggs then kholer engines whic is wat u see on todays machines

Just a small update here. I've been working lately, trying to get some cash built up to fund my projects. I figure in the next week or so I will go ahead and order 2 carb kits and start rebuilding them.

Here's a picture of one of the intake manifolds. The gasket is the same size as the carburetor. That opening is so tiny. I'm really wondering if that small of a hole even lets it get up to the governed speed ?

If that's how it was stock, then yes. I'm supposing you could port it...

Not only will it reach it, but will go well beyond it. Any induction part inside diameter should have roughly same inside diameter as carburetor venturi.

 

[Pyrotechnic]

You mean the same size as the venturi at it's smallest point ? That seems to be the train of thought with this motor when it was designed.

I guess I'll leave it alone then. If anything, I might try to blend the transition from large to small, would that even be worth doing ?
