MGB tune up - Timing and carbs

I get the timing and the carb balance and mixture dialled in a lot closer to the mark on my 1980 MGB.

Love the wire trick. Accessory shops don't seem to stock strobe lights anymore.

[@Endfloat]

Yeah, sure no new cars need strobe lights (unless the driver is a raver)

[@windmill1965]

You showing how to use two wires is enlightening; I will try that next time on my '64 MGB. I don't own a mass flow meter to measure the symmetry, but do have an anemometer. So instead of kg/minute I get a meter/second (i.e. speed) reading. These meters are very cheap and readily available. This works well to get both carbs run symmetrical in idle.

Loving these and learning loads thanks to your way of getting things across. Great stuff, sir. 🙂

[@scottishcarenthusiastsandtrain]

Another great and Informative video Ross, I am really enjoying this series on the MG.

[@wallisparnell4464]

Been looking for this, to setup my hew engine…excellant

[@sascenturion]

Interesting stuff! ...😀👍 Thanks for posting

[@americanpatriot2422]

Always an outstanding video and presentation.

[@Endfloat]

Thank you very much! And thanks for joining me along the way!

[@kt3537]

Great video ...your better than any 1000 page manual🤠

[@Endfloat]

Well now, I don't do everything right!

[@MGB-learning]

Great video!

[@anthonygowland8363]

Nice one... some techniques there that I hadn't come across before..thanks!

[@paulmuff9883]

Great video and I would always leave a B on the rich side 👍👍

[@nigelbeaumont1109]

I use a Gunsons colortune… fool proof. Great video.

[@hankpb1]

I've never seen the wire method before...handy tip on my tr7

[@David-wy9jl]

Great looking GT and thanks making this tutorial. I always thought the advance timing was 14 degrees BTDC for dynamic tuning, 10 for static. Maybe it depends upon which year, which carb setup and which country. More advance is usually more HP. You can also check at 3000 RPM for total advance, usually 32 degrees. You can add a mark to the pully.

[@Endfloat]

Now you've got me questioning myself! I shall consult the manual!

[@spellacy29]

Enjoying these videos. Such an original car (apart from those ubiquitous minilites) so hope you're gonna keep those orange striped deckchair seats, they're so 'of their time'

[@Endfloat]

You wouldn't be a fan of the minilites then? I quite like them. If the car didn't come with them, I'd have been happy with the rostyles, mind.

[@spellacy29]

@@Endfloat it's subjective I guess. I get a little disappointed when I see so many cars at shows with silver minilites. Everything from Alfas to Zephers, when their original wheels or hub caps were often much more interesting. Rostyles with chrome trims/beauty rings look pretty cool imho 🤔

[@bshnabel]

Nice GT

[@scoobyben1979]

Awesome video. That's helped me a lot. I'm going to give it a go this weekend. Mine sounds lovely and beefy but lacks a bit of power. Timing is bang on so Carbs next.

[@Endfloat]

Let me know how you get on!

[@scoobyben1979]

@@Endfloat They're balanced perfectly. But I think I messed up the jets 🤦‍♂So I need to set it back to base settings again

[@brianmac8260]

Fair play Ross. sounds wicked. Still noodling on the P6, I have me front Carb done, except for the throttle spring. complete pain in the thumb!!

[@Endfloat]

If I remember correctly, I used the throttle lever to turn the spring before pushing it into place fully.

[@garyowen9044]

Love the pink Barbie convertible in the background. Is that in for a tune up :-) ?

[@Endfloat]

I pulled it from a skip for my son and put 2 new batteries in it and fixed a switch and it works great now! Only had one battery originally but the extra battery in parallel gives the much needed extra current for the one wheel peel! 😎

[@duncanwilson9020]

Any ideas how to unstick a lift pin? My rear carburetor (1970 mgb gt) has a frozen one. By the way, great tutorial I am gonna be tuning my own carbs soon enough.

[@douglasgreen437]

Get an old Colourtune kit...In the kit you get a special spark plug with a see-through window on it...So you can run the engine & adjust the mixture on each carb to get the right colour combustion....Great video...🤔

[@Endfloat]

I actually only found mine there yesterday, so I'm going to give it a go.

[@erikherrera9527]

😎

[@DavidUKesb]

The wires are by far the best method as you can check for balance at higher revs. If using such method there's no need to disconnect linkage. Another advantage is that there's no need to remove and refit air filters

[@Endfloat]

I don't get how it would work if you didn't disconnect the linkage. Surely to get the carbs balanced, you need to be able to adjust them independently, no?

[@DavidUKesb]

@@Endfloat Because with the wires you're balancing the height of the air pistons, not measuring air flow itself. I could never work out why the linkage should be disconnected during this process so I rang the technical helpdesk at the MGOC who confirmed what I suspected. NB. Very much looking forward to seeing the process of the MGB.

[@wallisparnell4464]

Use wires about once month to keep SUs tuned, promise make a vary reliable car. Takes you 10 min. To make any little tweeks.

[@sollywelch]

just checking, your choke is fully out when balancing the carbs at the start?

[@Endfloat]

No I turned it off.

[@TheCaffeineRacer]

Which plugs are you running in your GT ?

[@Endfloat]

NGK BP6ES plugs if I remember correctly.

[@MathiasDavidsen]

In your video you say that lifting the pin, and rpm going up you say it is too lean. I have learnt that it is the opposite.. Just wanted to mention it

[@Endfloat]

Yeah I think I got mixed up at one point. In any case, it shouldn't rise or fall if its adjusted correctly.

Recognised you at the zoo on Sunday! I knew this was the car you described, I was looking at it myself, but didn't end up going for it, got mine on a lift on Monday. Panel beater was "Pleasantly surprised" by the condition, which is nice! i.postimg.cc/bJ8FqvFL/1663631321190854.jpg

[@Endfloat]

Ah good man! Yeah, as I said you were the first person ever to spot me out in the wild! 😎 I was chuffed! That's great that your car is in good nick. How come you didn't go for the one I have?

[@hio54]

@@Endfloat So I rang the guy selling it, he told me he was selling on behlaf of someone who was a bit older and didn't use it anymore, but also told me it didn't run, and hadn't run in a few years. Maybe three? So I was looking to buy my first B, which also happened to be my first car! I was advised to go for the most solid example I could afford. Since I didn't have the hands on experience(Yet) nor the garage space to do a full engine rebuild. Here's me thinki9ng I'd just need to do some paint touch ups! So I went with my one. In hindsight, maybe not the best idea, but hey, I love it all the same!
