picken up an engine #3

[Kenny_McCormic]

First it needs to be measured to see how big of a bore it needs (there should be a ring of untouched metal at the very top of the bore, is there a ridge between this and the rest of the bore?), then you have to buy the parts and have it bored to fit them or bore it yourself with a flex hone. I would recommend you have a small engine shop do it for you.

 

[sayre315]

its a cool bore (aluminum) threres no steel sleave
i'll have to find a machine shop
how much should i bore and how much would you say they would charge?

 

[oscaryu1]

If you're going to bore the block, those rings I sent you will be useless. They're standard bore.

You'll have to go oversize... oversize piston and rings.

I've had a couple of scratches on my cylinders. However, only 1/20 of them extended from the top to the bottom of the bore. Most stopped where the piston was at the very bottom... (BDC?)

Did a quick hone, broke it in on Castrol HD30, added a bit of Restore w/ CSL, and it runs absolutely great. One pull starter. You saw the video sayre

 

[sayre315]

where can i get CSL?
oh i went to o'rily auto parts and got a flywheel puller(3 arms) valve lapper and spring compressor

 

[oscaryu1]

LOL @ flywheel puller. That's just a standard (probably 6") 3 jaw puller. Flywheel pullers screw into the flywheel and pull it out. You'll pretty much break it with a 3 jaw puller...

All you need is to hit the end of the crank, while using a pry bar and it'll pop right out. Seeing as someone didn't weld or JB weld it on

Restore w/ CSL (that's what it's called) is a oil additive. I can swear it works. The trashpicked lawnmower gained so much compression you slowed down pulling it, as with my other engines that started easily.

It's in a little silver can. Here's a picture:

 

[sayre315]

im gonna have to get some

 

[oscaryu1]

Kk, just do a quick hone for now, break that glaze.

 

[sayre315]

how do i hone it? vary fine sand paper?

 

[oscaryu1]

NO! NEVER sandpaper! This isn't a weedeater... this is a 4 stroke Briggs 2 horse.

Generally, I use this:

You can find those at automotive stores of Harbor Freight (look for it yourself, they have NO IDEA what it is. They lost a customer because of it... I overheard the convo lol)

Remember, lube it when honing. Honing oil or just plain motor oil works fine.

 

[sayre315]

are those some kinda stones on there?
do i spin it with my hands?
does it have springs on it so it expands and puts pressure on the bore?

 

[jr dragster T]

No you will NEVER be able to spin it fast enough with your hands. You use a drill, As you can see at the top of the honer. And Yes it has springs to push out on the bore a little bit.

The engine restore stuff is basically leaded oil, the oil burns on the cylinder walls and leaves lead deposits in the scoring.

CSL (IIRC) = Copper, Silver, Lead.

So there is already lead in there. But hey, it works. As long as you don't run it on like 100% of that stuff, you should be fine.

 

[sayre315]

well i have carb problems

t wont start and theres gas leaking outa the part where it atatches to the tank and on the choke end
also i think the needle nut is stripped, would that keep gas from getting to the engine?

 

[2or3wheels]

sound like needle and seat issues. as far as outa tank, thats sompletly differnet. wait if this is a briggs then a few gahskets and your good, put a .61 cent gasket in my 4 horse briggs runs like a charm.

 

[kibble]

.61 cent

Dang! That's some small currency! :arf:

Sorry, I thought it was funny.

 

[sayre315]

so would i need to get a new needle? i know for sure its stripped pretty bad
oh, and i when to Advaced Auto parts taday and bought some liquide gasket and some of the restore stuff but i looked at the honing device and it was $30!!!

 

[oscaryu1]

It's about $20 shipped on eBay.

You can buy rebuild kits on eBay. Include stock jet, needle, ect.

 

[thatkidrob]

wow i have the same exact engine, good job on it though, mine wouldnt start either, i had to tear it down, clean rebuild, check the points, lol, only thing different is mines a 2 hp (sson to be more when im done with it, lol)
