holy crap that stuff is expensive
russ, could you tell me waht kinda LB i have as model, year, hp ect?

[Russ2251]

Serial number indicates that it's a 1978 and is a model F engine.
Horsepower ratings are a little foggy. I have model F's that are 4 hp while others are 4.5 and 5. All the engines are identical (bore, stroke, induction) to each other so I do not understand why the hp ratings are so different. They all behave like 4.5 hp.

[sayre315]

do you think it could be the carbs that make a HP change?
BC on this one i have a small plastic carb as upposed to the other F had a bigger one that was metal

[Russ2251]

All the carbs I have (and have seen) all have the same size venturi and bore sizes regardless of what was used to construct them. The plastic carbs are made of Minlon®.

[sayre315]

minlon?
thats a sort of plastic right?
i am still needing LB parts if anybody is wondering
please dont take this in the wrong way Mr. Russ but im just gonna keep looking unless i cant find anything else

[Russ2251]

I believe your CDI pack is 'ground to run' which is an early design.
Most L-B packs are 'open to run'.
Both are essentially the same, they are just 'turned on' in different ways.
Try by-passing switch and check for spark.
If no spark, try baking coil. Most of the time it will resurrect a dead coil. This should be considered a temporary fix, although I have a few that have lasted a couple of years.

[sayre315]

ok
so some run with a ground and some run without
i already baked it BC i thought there was probebly a problem with it and i didnt think it could hurt it
so your saying just bypass the switch with a straight wire and if that doesnt work try bypassing the switch with nothing?
i'll try it
thanks alot Mr. Russ

[sayre315]

Mr. Russ
do you think this LB would be a good one to make a kart engnie out of?

[sayre315]

well um i tryed it and it gave me 2 back to back sparks then it stopped and i messed with everthing and still couldnt figure out wat was wrong

[Russ2251]

Yes

Yes

Sometimes baking doesn't work. If your so inclined, try Ebay for coils. I've seen them used going for around $10. Problem is you're taking a chance on a coil that may or may not work.
I have also seen them new for around $29 plus shipping.
Check around at local lawn mower repair shops. Ask if they have any good used ones they would be willing to part with. Usually they have a pile of mowers waiting to be scrapped for aluminum content.
Won't hurt to ask.

[sayre315]

so outa those two coils that you have on those websites you gave me
does it matter witch one i get?
will this coil fit?

[Russ2251]

Both numbers are the same coil. L-B numbering system was recently updated.

will this coil fit?

Yes. According to my cross references, it will fit and work.

[sayre315]

ok
thank you sooooo much Mr. Russ
i found a switch on ebay for about $13.00 shipped if i win it but i have a strong feeling i will win them both

[jr dragster Tyler]

Why are you going all out just to find a stock switch? Just go to radio shack and buy a toggle or something.

[Russ2251]

Mr. Sayre wants original and wants it right as I do with any restoration.
Any hack can get something to work. The hard part is getting it right.
Bigger payoff in the end.
I commend him.

Sooooo, now we're all hacks, I see? LOL

Didn't say that, but a pitiful few of us are not.

[sayre315]

its BC i thought about making this into a kart engine but decided not and there reasons are
it has a pretty much rust free deck, nothing is damaged and i need the money
so im just gonna wait to get a LB that is damaged that way i dont feel bad about taking apart a great LB
the way i make my money is buying non working mowers and/or cheap mowers off of craigslist and garage sales
fix 'em and ssale them later
and those lawn boys sell REALY fast down here
