Thanks for the video! By the way, the music is fantastic! What is it?

That's why float height is so important.

Yes, it is the same.

This is the same style choke as my 78 cb550. ... (I know these are not the carbs but the style is the same with the spring positions)

Thank you.

Great video👌🏼🥂

I think i got something backward, when i push on the choke shaft part the cable pulls none of the butterflys close

Which slot is stock position??

This is very hopeful. So the correct height of the float bowl is when there's a hairline gap between the metal tang and float valve button.

How many times does one have to wind that spring?!?! I cannot get both sides to spring back like yours

thanks, this part of carb reassembly is a bugger! you make it look too easy. doing a 79 CB650 now but will look back at a 81 CB650 CV carbs i did last year to make sure ok.

26mm from under head to end of bolt. I used a washer also. One important note. The head will need a lot of heat before those original studs will come out. Try to do it right after a long ride.

Hi @Mike Nixon, what is the length of the bolt you used to replace the studs in the cylinder head?

How much torque did you put on the screw for the carburetor bowls?

Dave, have you tried my method?

My 1975 CB750 is a pain in the ass to get on the centers stand. I'm not sure why. It was even harder when I first bought it. I didn't realize it had lowering blocks on the rear shocks. I took those off and it got easier to put on the c-stand, but it's nowhere near as easy as my 1964 triumph 650...that bike goes onto the stand with barely any effort.

Nice one Mike. Clear accurate & concise.

80mph speedo on 140mph bike...USA does some strange things

Used your handy guide booklet on valve clearance shims...my bike would spin quite a while before starting...now fires up just like this video thanks. I have your other booklets and live in the UK..so easy to read and understand and the additional tips..like tapping the valves before starting invaluable...

My apologies to anyone who has tried to communicate, ask questions especially, and not received an answer. TH-cam and Apple's iPad seem to have some incompatibilities that make it difficult to find and answer comments. I got an email from TH-cam today saying someone asked about float timing. But the question does not show when I go into TH-cam. The timing as shown in the video is, at the measurement tool setting, the float valve should just have closed. Not before and not after. This is why you barely lower and raise the float, to gauge this timing.

Mike Nixon do you start measuring float height when the metal tang is just barely touching the shock absorber on the end of the needle valve

Thank you much!!!

Frank, you are very welcome!

Thank you for making this video!

Does anybody know where I can get a replacement for this spring?

What a beautiful bike! Im still cruising around on mine! Thanks for my carb rebuild and the guidance on Sta bil

so good video, many times pictures are enough to explain. short, concise, great 👍

Glad it worked out.

Mike....thanks for sending me to JR. He just sent me pics of my rebuilt carbs....gorgeous. He is a wealth of knowledge and a great guy to speak with....we have had several very long conversations.😉After 7 years I'll finally begin building my CBX. It has Carrillo's, Megacycle cams, a one off cam sprocket system, 67.5 Wiseco's etc etc etc. It should make 120 NA RWHP at least I figure. For crying out loud....my SOHC CB750 /1000cc makes 106.7! 😆

👏👏👏

thank you so much for this video. saved me alot of headaches..!!!

Thanks Dave!

Nice work Mike.....sounds awesome (Dave from Australia!)

Its a shame you have to buy an entire assembly to replace that one spring. Thanks for the video sir!

Any chance you could help me figure out my issue? 79 CB750K. th-cam.com/video/ZJlPt0aWUdw/w-d-xo.html

Graham, email me at carbrebuilder@gmail.com

Graham, Hondabond 4 is for the half-moon cutouts, just as shown in the official manual, and of course for the crankcase halves. To glue the gasket to the valve cover, use 3M #70 or #80. Both are very good and what I use.

Hi Mike can you use Honda bond 4 to keep valve cover gasket in place so it does not drop when turned over on cbx1000...as I'm refitting a new one after doing valve clearances...using your fab..booklet.

Spares are available , please let me know

Great video. Thank you for the technique.

Which carbs, DOHC four? Or CBX1000? Or SOHC four? And which model?

I just finished the spring ,works grate after adjusting the butterfly choke valves, need help with the the small brass plugs holding the tiny jets in .One has a small very tiny hole in it , What carb does it go on? #2?

I've always done it with my back to the bike. This seems easier.

thanks

Life saver!!!

Hi, Glenn. Have someone do it who knows the carbs well. I am one, but it does not have to be me. But before that, eliminate the stuff that isn't carburetors.

My rebuild did not work... any suggestions?

If you can rotate the screw more than 360 degrees it means someone has hacked on the screw head (cap) with a dremel. So no, you don't need to remove the cap, and yes, the screw is being adjusted. But that is a crappy way to do it. The cap should have been removed instead.

i can turn the flag all the way around no stoping is this not adjusting the muxture?
