I prefer buying two Colortunes at once and placing them side by side in cylinders no 2 and 3 for this tuning task. You automatically synchronise both carburettors in one go. Afterwards, after a long drive on the road, take out all sparkplugs and check on eveness in color and correct carbs in minute steps if needed. Always evade a singular spark plug going bright white, because then also your valves in that cylinder may be in danger!

Colortunes are great, I faffed for ages unsucessfully with my mixture until I got one of these. Thank you

Ive wanted to use my colortune on my mgb for ages but didnt quite know what i was doing. This vid is superb!!

GREAT VIDEO, NICE CLEAN ENGINE TO.

good show!

I've still got mine from when it first came out and has seen some sterling service over the decades, used to have it all, the meter, spark tester, balancer and out there on me Triumph's and must say that these work on Vespa's beautifully making a critical job very easy as a lean engine is heat seize city on them 2 strokes :)

Yes will work on 2 stroke , but check the size of your plug

Yes, It does not matter on your set up , it will work just the the same

it'll work in place of any spark plug of the same size

make sure the engine is fully warmed up before starting this....

What size would i need for a Wolseley 18/85 6 cylinder twin su carbs

Excellent video. Can it be used on two strokes.

Will this work using a Weber DCOE 45, obviously the mixture setting procedure is different, but would I be able to use this product in a similar way?

I d like to ask ,does it work on normal ignition or has to be electronic?

Wolseley would have 14mm plugs
