X2. I easily get a little too caught up over-engineering things. I'm constantly reminding myself it's just a fun kart. I'll take it for a test run before I tear it back down to paint. If it works, great. If not, I'll figure out something else.
Good luck.

You mean an update? Nothing major currently. Been takin' it easy over the Holidays and also just made a career change. Been unpacking boxes and getting settled into my new work digs.
Keep forgetting to order 2nd motor mount plate from RobRon. That's the last bit of major fabrication on the frame. Then just some brackets for throttle/brake assy's and cleanup. Next up is getting the short blocks back together. Closest LawnBoy dealer is 1hr away. I'm down there occasionally, so I'll get my rebuild parts soon.

Quick question for Russ
Hey Russ,
I hope all is well. Short blocks are coming back together. I remember reading in one of your posts that when you changed out your reeds to the CF ones you made/bought, you noticed you picked up a bit of mid-range. But you also said you made another change at the same time (maybe clutch?) and not too sure if the reeds made much of a difference. My question is do you see changing out the reeds as a very beneficial mod? I wouldn't even begin to know how to make my own reeds.
BTW, pulse-ports and no head gasket. Check.
Thanks.

i think the guy who made carbon reeds just bought carbon fiber sheet of the same thickness as the original reeds and just traced and cut them out. i think you can get carbon fiber sheet at mcmaster carr

Here's what I posted on another thread:
Link I posted has .015" or .023" sheets.
Either one could be used, but I do not know how the differences in thickness will (or won't) improve performance. Could be a backwards step.
As with everything else i do...it's a trial and error thing.
Other change I made was to final drive ratio.
I went to a 66 tooth driven sprocket, but have since switched back to the 72 tooth set-up due to low end lag.
It turns out that these reeds are .0165" in thickness.

Addendum to previous post:
Ebay has tons of Boyesen reeds available.
No specs concerning thicknesses are posted. They may vary from engine to engine (Honda, Kawasaki, Yamaha, et al).
I just may have been lucky with what I received. Will require some further study and/or trial and error to determine which works best.
Keep in mind that the thinner they are...the better the chance for high end flutter.
At well over 6k rpm (double factory spec), I have experienced no problems at all.

What is the benefit of the carbon fiber? Do they bend more easily allowing more air/fuel? So if I go too thick I could be shooting myself in the foot. I have some old McCulloch reeds that look to be CF, but they may be plastic. If big enough, I could just cut those in the shape of the LB reeds? I'd rather not get into too much experimenting, especially with the reeds since to change them out I'll have to tear open the motors again. Knowing my mods Russ, would I be too bad off just running the stock reeds for now?

Reeds - The In's and Out's
This whole endeavor is an experiment and will continue to be so. I could have purchased a palette of clones for all the time, effort, labor, and dollars I have spent on this thing already. I did not want what everybody else has.
If something works, I stick with it and improve upon it.
If it doesn't work, I try something else.
Probably not.
Just have to know where to draw the line.
My original goal was to hit 50 mph using only stock push mower engines. Having accomplished that, it's only logical that I take it a step further...that is going faster.
If that means tearing down both engines for the eighth time...I will do it.

Thanks for the feedback Russ. I appreciate your take on it. I wholeheartedly agree with you that any project like ours is an experiment. However, with building this thing from the ground-up, there are alot of variables I need to work through (carb adjustment, clutch engagement, final drive, etc.) and I think any performance improvement can be left until later. My goal is to get it up and running. I'm sure I'll be tearing into the motors in the future, so I'll make reed changes then.
Thanks for the link on Reeds 101. Very helpful!

Nice Work!! Great kart!!
Say, what did you do with these wheels? One pic looks like you replaced them. I'm needing some exactly like 'em for my General Lee kart resto. Yours are the only others I've ever seen. I'd be glad to take 'em off yer hands.....

Fast Eddie, PM headed yer way.
My general is actually The Rebel made by Clark MFG. They previously made an actual General Lee go-kart complete "01" flag and "General Lee." My guess is that they didn't have proper license or it expired and mine was post Dukes of Hazzard.
Here's the frame
Model Serial#
the old wheels
and some I picked up on a kart from CL that look like yours

Hey Russ,
Another question for you. Sorry for posting but I can't PM you for some reason. Check out these carbs on eBay. Emailed them if they were 293 B's and he replied that they were 293 F 428's (huh?). Plus he said they should be rebuilt before using. Would these work? What are they worth if I have to rebuild 'em? Thanks again for your constant advisement.
Krate,
Got your PM from last week. Sorry. I'll snap some pics and get em to you.
Ken,
Check your PM.

I have no specs on that carb. Carb I use is hl239b and not hl293f.
If specs are closely matched to the 239...should not be a problem.
Can't tell from Ebay pics if these are set up for an external pulse line or not.
This one looks promising:
Tecumseh bowl carb and is fully adjustable.
If bowl carb is used, adapter plate must be used (obviously) to position carb correctly.
Another Tecumseh bowl carb to consider.
