I feel like you should just order 2 mikuni carbs in each size and keep one at your parents + one at the shop of each 😛 It seems the answer is always "just swap the carb" when you guys go to an old motorJuly 28, 2020 at 8:54 am #135467Kris Roberts
Carboureter for aircraft don't have a float valve or the engine would cut out at strange angles!👍July 28, 2020 at 8:54 am #135468neo 71665
Pretty sure I've said this a dozen times on deaf ears.
Electric fuel pumps push better than they suck. Put the pump near the tank where it belongs. There is a reason why you only see modern cars with pumps in the tanks. The use the fuel to cool the pump and its where it supposed to be by the tank.
Either get the correct rated pump or put a reg on that thing.
Honestly I'm surprised they let you threw tech last time.July 28, 2020 at 8:54 am #135469John Doe

Look at Rotax airplane engines,some of their carbs work upside down. Or Look up a vid about how the spitfire engine works that wil explain allot.July 28, 2020 at 8:54 am #135471Incognito Bandito
oil leak gag at the end hahahaJuly 28, 2020 at 8:54 am #135472Snowiercoyote
What would be cool is you and him put the 670 snowmobile sled engine in that and make a cooling sistom that would be fastJuly 28, 2020 at 8:54 am #135473Steve Jacobson
Put the 2 stroke you guys just got on itJuly 28, 2020 at 8:54 am #135474keaton beckham
im pretty sure airplanes use diaphragm carburetors like the ones used on chainsaws, weed eaters etc… so they can work upside down. might be called pressure carburetors.July 28, 2020 at 8:54 am #135475Raggsey1
That was funny just at the end with a fork lift named exon valdezJuly 28, 2020 at 8:54 am #135476Ethan Keeen
Needs the 100hp two-stroke on itJuly 28, 2020 at 8:54 am #135477Marclar
Aircraft carburetors are specifically made for aircraft. They are often more complicated than normal “small engine” carburetors as well as having an FAA manufactures airworthiness certificate. In other words to make and sell carbs for aircraft you need that cert from the FAA. There are also regulations about changing the “stock” carbs on any aircraft. In order to change to a different carb (unless it’s on a list of FAA approved carbs for your specific engine) then you need what’s called a supplemental type certificate. Again, in order to attain that, you need to be in touch with them FAA. Long story short, the difference is the regulations surrounding the aircraft carbs. In theory they work the same as any carb. And of course there are float type and pressure type.July 28, 2020 at 8:54 am #135478Gareth Wick
I'm so glad it's out of the shed!!!
You should put the 2stroke on itJuly 28, 2020 at 8:54 am #135479John Daniels
Man you guys need to start building up spare parts and keep them organized on a shelving unitJuly 28, 2020 at 8:54 am #135462adminKeymaster
We built this 60s inspired miniature drag rail about three years ago with a modified Harbor Freight 670cc V twin making about 55 horsepower. Our engine had a …July 28, 2020 at 8:54 am #135463friscoHub415
The same thing happend to my 5th scale rc baha a rock got in there and killed my coil……you guys should get a couple of 5th scale RCs they use chainsaw engine same style of stuff like your go carts and they are super fun brosJuly 28, 2020 at 8:54 am #135480AgnotologyTV
you just ever going to swap the driver position with the engine? The biggest performance gain you could make would be to remove those driveline losses by the jackshafts. plus you'd pull almost 100 lbs out of it. Bet you'd drop to mid 8's in the 1/8thJuly 28, 2020 at 8:54 am #135481ST2
You should take the engine off from dukarti and put it on the dragster. I said that 2years ago😂July 28, 2020 at 8:54 am #135482Matthew Povey
When do we get to see the truck in all it gloryJuly 28, 2020 at 8:54 am #135483Bradley J. Fortner
This thing needs some competition. Something else that goes really fast and really straight. A drag mini-bike maybe? I don't know. But, SOMETHING needs to be in the other lane.July 28, 2020 at 8:54 am #135484Christopher Mariscal

I say it will run an 7.75 in the 1/8 mile.July 28, 2020 at 8:54 am #135490dr reckoff
I would love to see you turbo charge that motor and build a new rail with the motor in the rear ,maybe check into some real junior rail slicks instead of the turf tires ,just some thoughts for future episodes!!!!July 28, 2020 at 8:54 am #135491demonic477
I have to say if you want to boost this V twin you can use a AMR-300 or a AMR- 500 supercharger . if you look on Amazon there 220 bucks but If you look on Alibaba you can find them for 120 bucks for a rebuilt one there good up to a 2.0 litre engine for the AMR-500 model or a 1.7 litre for the AMR-300 . I would love to see the dragster ripping up the strip with a blower on it .July 28, 2020 at 8:54 am #135492BIRTHDAYFACE046
Some Robinson Helicopters use CarburetorsJuly 28, 2020 at 8:54 am #135493Mi Scusi
Red beard's garage has done a supercharged 670, maybe an idea for this thing. It would b a rocket.July 28, 2020 at 8:54 am #135494cole cole
The torque converter is rated for 50 horsepowerJuly 28, 2020 at 8:54 am #135495demonic477
whenever you have a simple gap set up like a lawn mower or a old school points set up on a car you can get away with using a match book flap as a feeler gauge to set the gap . most match books are made with 3 mil paper so it's about perfect for setting the gap on a mower the points on a old beater car. I own like 5 sets of feeler gauges for all kinds of old points set up's and I still fall back to the match book for my old dodge's points . the best part for doing a mower mag is you can put the match book flap between the fly wheel and the mag and just tighten the bolts the match book will slide right out after your done leaving the gap perfect and ready to run.July 28, 2020 at 8:54 am #135496Atomix

Subaru likely make aircraft carbs. I think aviation carbs are the origin of those slide carbsJuly 28, 2020 at 8:54 am #135499Keep flying Race up
