Dicky Blighter Posted April 28, 2009 Share Posted April 28, 2009 Just a thought here, when I fitted my new carbs at the weekend I took the opportunity to add a couple of vacuum take offs ready for the Megajolt install. I should be able to use these with a vaccuum gauge (or even using the readout from the Maegajolt) by reading one at a time and blocking the other to balance the carbs?Be much easier than messing around with the crappy plastic Gunsons Carbalancer that falls apart every time I use it.Any thoughts.?

GT6boy Posted April 28, 2009 Share Posted April 28, 2009 Good idea Dicky! I used the Gunsons item for years, but once the car went to triple SU's which already had the vacuum advance take-off individually fitted, I used these with a proper set of gauges and was amazed at the degree of accuracy possible when balencing 8). Far superior to the 'okey-dokey' method with the plastic juggling ball. Link to comment Share on other sites More sharing options...
Dicky Blighter Posted April 28, 2009 Author Share Posted April 28, 2009 In that case I shall wander round the motor factors at lunch time and buy a lo-gauge Link to comment Share on other sites More sharing options...
Mj17 Posted April 28, 2009 Share Posted April 28, 2009 Not having individual pressure take-offs I'm a convert to one of these - http://tinyurl.com/cmh7lcMuch easier to use than the Gunson and only a little more expensive. Great on the Spitfire - just a shame the wing gets in the way on teh saloon's rear carb :( Link to comment Share on other sites More sharing options...
GT6boy Posted April 28, 2009 Share Posted April 28, 2009 These are my gauges. This was when the cam wasn't timed in right and I couldn't get them to balance properly. Now i can get them spot-on 8). There are loads of cheap versions on Flea-bay, but I understand the needles arn't damped particularly well, so the needles tend to dance around a lot?

Webers or SU's?If SU's can you show me your take off's :)ThanksROb Link to comment Share on other sites More sharing options...
GT6boy Posted April 28, 2009 Share Posted April 28, 2009 SU HIF38's. As these came off individual Metros, each carb had its own vacuum advance take-off just the engine side of the throttle butterflys. The link to the singlke carb instal on this mini shows the same take-off as a small bronze push-on union on the top of the carb to inlet manifold mounting face. http://images.google.co.uk/imgres?imgurl=http://i241.photobucket.com/albums/ff85/Capt_bj/mini/Carb2.jpg&imgrefurl=http://www.northamericanmotoring.com/forums/classic-mini-talk/148699-can-you-help-id-my-carb-please.html&usg=__eRYz5YhCZDEDeXOK7b0-ou_m9WI=&h=768&w=1024&sz=201&hl=en&start=6&sig2=H8r_V0jRGjHXZhVh5OVhSQ&um=1&tbnid=wViEmJBk9GwgyM:&tbnh=113&tbnw=150&prev=/images%3Fq%3Dhif%2B38%26hl%3Den%26client%3Dfirefox-a%26channel%3Ds%26rls%3Dorg.mozilla:en-US:official%26hs%3D0Hu%26um%3D1&ei=i2f3SYr8H8K1-Aa7hoG6Dw If the link doesn't work, I can put a pic of my car.

Deleted User Posted April 28, 2009 Share Posted April 28, 2009 Ahh all becomes clear! Thanks.I had single take offs on the Webers (x4)but on the Su's I use a different tool!just looking at adding extra take offs to the mainifold but not sure if this is worth it with the balance tube?Rob Link to comment Share on other sites More sharing options...
