You really got that engine cleaned and shined up. Incredible job RfWi. The paint job is nice IMHO.

You have a great little vintage Lawn-Boy.

Re: LBAD strikes! 8F20K

Where do you guys come up with these old vintage Lawn Boys? The pics all conjur up memories of the old guys in my neighborhood cutting their lawns with them. And in those days, without the high quality synthetic oil, they sure did smoke a lot. Now, I'm an old guy, too.

Re: LBAD strikes! 8F20K

It was a good day for painting,so primed and painted deck.I just love the detail cast in these decks.No wonder these Lawn-Boys really weren't cheap.Over $800 in today's money!

Re: LBAD strikes! 8F20K

The amount of knowledge of about old Lawnboys here is astounding. The idea of mowing with 62 yr old mower pleases me. I pick up little factoids every time I drop by. One really useful tip was that the mixture screw for a F series is only a 1/4-1/2 turn out. Every other carb I ever messed with was a turn and a half out. I happened across that tip before I ever cleaned my first Walbro.

Yep,I think the paint guy did a terrific job mixing the paint.He didn't have much to go on.The only non-faded sample was under the model plate.Hard to tell from the pic,but there is just a touch of metallic,just enough.

Re: LBAD strikes! 8F20K

Well,getting close to the end of this project.I can't wait to see how it runs.
Question: Why did these models have three types of blade washers?

Re: LBAD strikes! 8F20K

good evening
to share what the washers are for this is how they mounted the blade
to mount the blade place the washers with flat spot on the crank first
then blade and other washers lock washer then blade nut i know this
because i have same mower it came from my grandfather who was a
lawn-boy dealer the mower was up in storage loft when i found it grandfather
said i could have along with another iron horse mower that first mower he sold is a 1953
model iron horse mower please let me know if you need more help your lawn-boy friend Scott

Re: LBAD strikes! 8F20K

It was just LawnBoy's idea of what was needed to make the blade turn with the crankshaft without slipping and to let is slip if you kit something solid. Correct sequence is large steel washer with D shaped hole, next rubber washer, next fibre washer, next stiffener, next blade, next large steel with D hole, Safety washer then nut. From picture you have extra fibre washer. If you had a 21 inch mower you would use a fibre washer between the stiffener and the blade, but you have a model 8F20K (18) inch mower that does not use the washer between blade and stiffener. After tightening the nut, bend one of the safety washer tabs to lock the nut to the shaft. That deck paint looks the best I have ever seen. A hard paint to match.

Re: LBAD strikes! 8F20K

I kind of thought that was the reasoning for those washers,to allow some slippage.There was a nylock nut on there.Since there is a safety washer on there,should that be a standard nut?Is the tightening torque less than a blade nut without those washers to allow the slippage?
I will certainly pass on all the compliments on the paint mix to the paint guy!
He did a bang up job!!

Re: LBAD strikes! 8F20K

I could not find torque setting for blade nut for D shaft models, but later models that use nylock nut shows z525 to 650 inch torque or 45 to 55 foot pounds. Either nylock or regular nut should be fine. If wanting to go for exact as original, use regular nut.

Re: LBAD strikes! 8F20K

Got this assembled and running! After remembering to open the needle valve,,it started on the first pull.Runs great,I even cut a little bit of grass.
Besides the fact the shroud doesn't match the decal as close as I'd like,I'm really pleased how this turned out.
