i've gone to the green side!!!

[sayre315]

i just picked up a lawn boy for $20 with a messed up recoil

i found out that it has no spark and i cant figure out why.

i'll try and get some pics up later

Welcome brother!

Too bad our definition of "green" and the governments/hippies definition of "green" are two totally different greens.

For a fleeting moment, I thought we were gonna have to deal with a tree hugger. ...Phew...I was ready to go into a political diatribe.

i found out that it has no spark and i cant figure out why.

If problem is coil/CDI pack, I have a possible fix. Get mom's toaster oven (not microwave) ready.
And no...we're not gonna make smores or cook up (dare I say it) spam!
Please post mower model number. Sticker should look similar to this and will tell me precisely what you have:

It's a model "F".
Get it running first before disassembling. $20 is a lot to spend on a non-running lawnmower engine. Don't want to waste time, effort, $$, on engine that may never run.
Be sure of what you're up against before doing anything.

hey russ, how do i fix the "no spark" part of it?
also, how many hp and displacement does it have?

 

[Russ2251]

how do i fix the "no spark" part of it?

There are 2 CdI configurations.
What you have is an 'open to run' CDI. This means that grounding lug should not be grounded to produce spark.
I have run into some non operating L-B CDI's and the following is what works 80% of the time.
Pre-heat toaster oven (not microwave) to 200° F max, and bake CDI for 2 hours.
When finished baking, drop CDI (while hot) into coffee can filled with enough WD-40 to completely cover CDI.
Gallon cans of WD-40 available at Home Depot and Lowe's.
Let sit in WD-40 until cool (about 15 minutes).
Reason for WD-40 is it's ability to drive out moisture which is #1 reason why L-B CDI packs fail.
2 reasons for baking:
1.) Drives out moisture.
2.) Heating causes everything to expand allowing WD-40 to 'suck in' to areas as CDI cools (contracts).
As I stated, this works most of the time but not all the time.
This is a cheap fix as CDI packs can cost between $30 ~ $60.
Don't forget to set gap at .010 inch using a feeler gauge.
Torque to spec, 25 in.lbs. max.
Use of torque wrench and correct feeler gauge cannot be over emphasized.

how many hp and displacement does it have?

4.5 HP and 127cc's or 7.75 cu. in.

Thats a good tip, gonna have to try that on a bad weedeater coil pack I have.

 

[sayre315]

thank you vary much russ i'll have to try that

 

[sayre315]

now that i think of it, the guy said that the recoil would'nt "recoil" so he just forgot about it
im thinkin after the recoil stopped working he just left it in his back yard and it got wet

it just rained the other day

 

[Russ2251]

May have broken recoil tryin' to start it.
Properly maintained L-B will start on 3 pulls max.
My L-B DuraForce kart will start on 2nd pull every time. 1st pull if warmed up.

 

[sayre315]

well it took a few pulles but... your idea works great

that thing is purring like a kitten now!!!
i dont know if i should sell it and make a few more bucks or convert it into horizontle?
hey russ, how much would ya say i could get for it?
mym kinda payed for it and i told her it was so i could make some money and if i didnt sell it i would just make a go kart or somthin

i think i'll throw it on craigslist for a week or so and see if i get any buyers

 

[Russ2251]

Not worth very much unless in 'like new' condition.
Got most of mine for free.
The ones I did pay for had low hours and were no more than 2 or 3 years old.

i think i'll throw it on craigslist for a week or so and see if i get any buyers

Yeah...post it and see what happens.
My guess is that you got your monies worth just by getting it running. Good show!

 

[sayre315]

you think i could get $50 for it?
i'll just have em' make an offer

 

[Russ2251]

Can't say for sure. Would have to find someone who really wants one.
Put it here:
