Briggs OHV & Vanguard / Briggs 23hp build
« Last post by Timdeere on Today at 08:03:51 AM »
Iam not here for a racing mower build but figured I'd go to the professional's here.

Iam a john deere mechanic looking to get a few more horsepower out of my 18hp gator
I've already decided to punch out the block to fit the 40ci intek pistons.
Then put the rest of a 23hp in and a 35hp carb as a cherry on top

Just a few things: do I need the rods from the 18/20hp or the 23 to fit the intek piston wrist pins?
Iam not getting billet rods in atm if it breaks it breaks and we go oversized with new sleeves.

Also is it possible or advisable to advance the timing gear on the 23hp?
Have heard it being done on the 20 but don't know for sure.

Also tips to improve on the engine are welcome.
Would love to add a better oil pump if possible but don't know if there is maybe an electrical oil pump that's good?

ive got parts galore like a kid in a candy shop but just don't know what goes where to make the best engine

Thanks in advance

Hi there guys and gals,

After last winter's substantial (for me) project, a '78 Fiat roadster resto, I got use to having a garage project for weekends and considered another. I've had an interest in small engines and antique lawn / garden tractors so I thought I might try my hand at a racing mower build. My arsenal has one candidate imo, which is an early 70's (my guess but not verified) Yardman:

 This was a freebie and I like the look. Frame sheet metal is thick and excellent cond. I have welding and fab skills, tools and access to a res. garage machine shop if needed. Also have a supply of 1'x1'x1/8 wall square tubing and some 1"x2". My iron worker friend has a scrap area I can rummage as well. I spoke a couple times to a local racer and discussed ARMA Super Stock build and printed rules / build rules. He said folks around here build to ARMA.
 Frame has been stripped of all components and I'm looking at reinforcing it. Mocked up on table w/ 4.25" ground clearance and need actual turf tires and decent wheels and hubs to determine live rear kart axle location and to-be-built front axle / steering design and dimensions.
 I have a couple Peerless 700's, a 5 spd and a 3 spd. I've gone through both and they are tight and excel. shape.
 Having never done this before I know will take longer but I'm pretty detail oriented and confidant I'll pull it off eventually.

 Here's a recent project I'm just finishing dialing in the belt drive and will cut a cardboard pattern for a sheetmetal guard today:
1960 Wheel Horse Suburban w/ new 212 Predator (just noticed the pic isn't w/ new engine).

 This does pretty good wheelies w/ new engine. Tractor also came w. original cart. This pic the day I brought it home:

 Also have a freebie Bolens ST125, w/ Briggs 12.5 opposed twin non running. Been troubleshooting this off-n-on, replaced magneto / coil yesterday and fired up for the first time in years. Will rebuild carb and get tractor working but not sure of any future plans.
 Also have 1956 Frankin-Bolens that's running, a very nice Simplicity hydro, and a '04? Craftsman LT1000 17.5 that's mint, pulley swapped and maybe someday a woods / mud mower.
 Oh, and a picture of the Fiat:

 I'm sure I'll be a regular visitor here and I'm look forward to learning from your expertise.
