4 HP briggs and stratton

[Russ2251]

Built in compression release or "Easy Spin". Compression doesn't reach optimum until engine is running. This is accomplished with valve overlap and/or special compression ring(s).

 

[tenlizard]

so my compression is actually higher?

 

[Kenny_McCormic]

Considerably higher.

 

[tenlizard]

which would be the correct model number for my engine for the tiny tach? here is link? which is correct one. it's a 4hp 4 stroke briggs. http://www.tinytach.com/tinytach/gasoline.php

Tiny tacs update too slow to be of any use for us. You dont really need one anyways, although watching the needle move about is very addicting.

It's of GREAT use to me. The CTT-II updates every .5 second which is plenty. I could not determine mph without it. Am purchasing a second one to monitor twins.

 

[tenlizard]

so which one of these would work with my engine? http://www.tinytach.com/tinytach/gasoline.php

 

[Russ2251]

Give them a call and be prepared to give them engine numbers.

OK today i was revving my engine when i noticed that gas was spurting/spitting out of the side of the carburetor near the diaphragm cover. i don't know what i should do. should i buy a new diaphragm cover on briggsandstratton.com? it says that i can't add it to cart...i have to find a dealer which sux.

 

[Russ2251]

Sounds like diaphragm is leaking.

 

[Kenny_McCormic]

New diaphragm time.

 

[tenlizard]

what does that mean should i buy a new carburetor or should i buy a new side cover or what?

 

[Russ2251]

New diaphragm.

 

[tenlizard]

is the diaphragm the thing under the side cover? like the screenage/gasket thing for it?

 

[Kenny_McCormic]

Yep, hardware store probably has one.

 

[tenlizard]

here is the diaphragm...it has no tears in it and looks to be in good condition. i don't know much about diaphragms though. how can you tell when they are worn? it's a little crispy around the circle area, but the rest of it is flimsy. here are some pics.

 

[Kenny_McCormic]

Replace it, its a cheap part.

 

[tenlizard]

ok i should also replace gas tank gasket as well? 3 quart requires 2 and i only have 1 that's worn down so should i get it as well?

 

[Kenny_McCormic]

Yea, might as well.
