little tip - if you don't already know, the choke lever on Hondas have a round tip that fits perfectly in the fuel line to plug it. comes in handy

[Deucealive]

Completely agree with you on using impact on everything. When I'm working on car, if I could get to it with my impact guns or air ratchet, that's why I'm using. My small engines also of course.

[kevinroberts]

I have a honda 270 but it has a tapered shaft. Can't put a torque converter on it

[BigRig]

Speaking of upgrades, do you know if a 340/390 cam will fit in a 270?

[bigtexas]

Been using ratchets my whole life I just got my first impact and might I say it's the best thing I've ever purchased. Some of those longer bolts take 10-20 maybe even 30 seconds to get off depending on the rust this impact all you have to do is spray a bit of wd40 on it and it comes off in 5 seconds or less

[MrRizza]

Can't wait for you to put a cam it one of these bad boys and see how it goes

[M.TTT.]

Good to know about that spacer, have a gx390 I was bout to put a filter adapter on.

Hey! Great channel RB! Extremely informative content! I’ve got a 9 hp Honda that i plan to slightly build . I ordered a toque converter for it and plan to use on my Colman ct200 mini bike. Any thoughts or suggestions? Keep up the great work. How ironic is it that this episode popped up 4 years later on the same day I ordered torque converter!!?

[sierraneese]

I got the 301cc with stage 1 performance kit with governor removed 40 series ctv lol. I love it just got to get the right size belt on 22" wheels

[redneckcomputergeek]

At 30k Subs I still have dummies telling me not to use my impact on case bolts LOL

[Builds]

so which carb worked best with the gx270 clone? I want to do performance upgrades on my gx270 clone, should I get the gx390 carb? or maybe a gx340 carb? I can likely make my own exhaust. I'm kinda on a budget, I could also re-jet my factory carb if that's beneficial at all...? thanks

[ise_cube]

do you know the right dimentions for the bolt to hold the clutch?

[CluelessEngineer]

What chain do you run with high HP engines like this? I have a 9hp Subaru Robin, and going to run a 35 Chain on my race kart with it and a torque converter. Will I have chain issues. Have you ever had strength issues with 35 Chain?

Hey rbg. Can you give a quick tutorial on the carburetor swap I can get it right

[jpwipeout]

Little confused on the carb upgrade. I get that the opening is bigger for obvious reasons but if the head opening is the same 20mm. Wouldn't it still be restricted? Also do u have to remove the oil senser to also remove the governor?

[seanpereira]

Hey Red Beard, love the videos, and the time you take, cheers from Oz.

Quick one, is it necessary to remove the governor as a part of the header / jet / K&N style filter upgrade? I'm confident to do everything up to the open heart surgery of the governor removal.

Thanks in advance!

[davinlyda]

Like the build. I am building a gx340 for my brothers go kart.

[kevinkuhle]

So did you plug holes with bolts, where you removed the oil sensor and the governor?

[mackdiesal]

Hey red beard I pulled the pin off the governor arm and the whole arm drop into case. Was that supposed to happen? And why would it do that? I had never opened the case before that happened

[treversteib]

Hey red did you but the gx 390 carb or the gx 340 carb

And what headed did you put on it
