Rat Rod Wagon High Performance Engine Swap! (Pt. 1)

The Rat Rod Wagon built from a Radio Flyer wagon tub has been one of our favorite (and surprisingly most reliable) projects to date. Since we recently came into some old school Briggs and Stratton 5 horsepower flathead performance parts, we decided to build a high performance flathead briggs and Stratton racing engine! When we chose an engine & began taking it apart, we realized that the briggs and Stratton 5 horse we had chosen was already built!

the lifter area wasn't broken, it is a weak area that is welded to keep it from breaking. it is a common practice on briggs 5 hp engines that are professionally built by engine builders. That was a really good eyebrow shave job too! If you end up finding out that the engine still smokes, it could be the valve guides are worn out, or the piston is actually rocking in the bore, even with new rings.

Obvious there are some old school B&S enthusiasts in the room. Great info. Wheel falling off, starter and rope problems, smokey running, brings back memories of my old Snapper Comet 26 lawnmower. Although my engine was a 8hp vertical. So worn out I had to use starting fluid to get it to start. Had to stop at half a tank of gas to fill with oil again. About once a year the starter clutch would hang up and make the most embarrassing squeal imaginable.

Hey just a quick tip, I think it may have already kinda been mentioned, but it’s a 99% chance that engine is set up for methanol fuel. The jets on the carb are drilled out much larger which is why you can’t get it to idle well. There should also be an offset flywheel timing key to advance the ignition to run on meth. Good luck with the build, love these old flathead monsters!

@dragata1 5 жыл бұрын

Holy cow you guys found somthing LOL that cam is a 107SS the 5's are S's the rpm range is 8500rpm 30ish LB of spring pressure 32-34 On ignition timing i can't remember the Lift the cam does but you should be able to find it Via Dyno cam's website or call them or email them and ask for the specs for the 107-SS cam it is a Very mild cam ran it in a few 5hp briggs Normally bore them out .15-30 over for this cam great thing about it was adding a billet Head some times you could get away with out haveing the relieving the head i know on the stock heads you did not have to but when i ran the 107-SS i ran Alky or E85 .

@dragata1 5 жыл бұрын

Also it might smoke depending on the oil you guys use i know mine smoked due to extra pressure in the crank case we ran 10w40 Royal Purple normally you would drill and tap the front of the crank case and add a catch can with a breather and redrain the catch can into the front oil drain just watch out for oil flowing into the carb at high RPM.

@dragata1 5 жыл бұрын

I would also like to note that rod is a Horstmann H Beam rod i have heard it being stronger than a ARC rod but i can't verify this but can tell you i have not seen one used in a good bit but alot of them where oversized and required the piston to be shaved a bit either way make sure you get the right rings proper oil and fuel and i promise this engine will be super fun shoot i might even dare say throw a mikuni flatslide and a billet head on it as well a billet flywheel.

@dragata1 5 жыл бұрын

After watching the video for the 4th time i really need to pay more attention to the videos the welding you seen above the lifter if i am correct it has brass inserts for the lifters and the welding that is done is more like a reinforcement because 5hp briggs where known for cracking right there under high rpm's with a large cam.

DUDE!!! I used to build those Briggs engines. The valve tappets get material added to them so they won't break when you put in a high lift cam! The lobe ramps up so fast, it will break the tappets right out of the block! That is probably a limited mod. cam, or an open class cam. They can turn 8-9000 rpm! I raced an open class cart back in the day. They'd run 70-90 mph depending on gearing! Awesome find! Check out the valve springs. The weight of the spring controls the rpm. If you plan to turn high rpm, get an aluminum flywheel!!!!! I saw one fly apart at the local track...a piece of hit a guy in the head and killed him! Nearly took his head off! No kidding...

The welds near the valve guides are there to strengthen the area. Flat head Briggs motors are known for cracking in that area. It was prepped as a race motor. You need to pull the valves, clean them, and lap them to the block. Clean up the carb and slap it back together. That motor will push close to 10 HP.

Built bunches of those. I used to think of you guys like 11 yo me, knocking around in the shed. reason i say is it took you guys awhile to figure out kill switches and relieable throttle return springs. now getting back to where i started like 25 years ago, really cool. say my buddys and i would use a steel flywheel key that looked half sheared to advance ignition timing for alcohol. also those old pulse jet carbs are a forgotten art but they can be rebushinged to get them tight again. so between the carb and tank you can use a peace of flat spring steel to raise the fuel level in the bowl. or build an intake adapter and use a motorcycle carb. lastly i think that engine was pretty healthy it just needs to warm up so everything can get tight. oh one more thing those alcohol engines run a light weight lubricant, can remember what we used but its similar to hydarolic oil.

I have seen several modified briggs flatheads with tig welded reinforcements near the lifter bores. In fact, if you go to DynoCams website and find their flathead cams, you'll notice almost every cam description recommends reinforcing in that area. On the Briggs Raptor III (not sure about the earlier ones) the block is much beefier and thicker in that area (between fins and crankcase it is noticibly reinforced from factory. I think the engine you have is actually a Raptor block

That's like our old racing engines. Chain guard on the timing cover and it looked like our racing oil (Thor oils I believe). 5 hp Briggs made 13.6 hp. Bullet Racing Engines in Knoxville TN built them. I would also bet that is a Dyno Racing cam. Also, that carb could be jetted and worked to run methanol.
