johny Posted August 10 Report Share Posted August 10 I think air is drawn in that little hole you can see in the photo at the base of the tube and once flow is enough the ball will be lifted up to float. If the hole is blocked or theres a leak where the tube connects to the body of the balancer then of course the ball wont move.... Link to comment Share on other sites More sharing options...
johny Posted August 12 Report Share Posted August 12 Hi Carba, any progress with your balancing? Heres a photo of you gauge with the entrance open which is how you should begin before turning the centre disc with your finger to close it sufficiently to make the indicator ball rise. Of course revving the engine will do the same thing because of the increased air flow.... Link to comment Share on other sites More sharing options...
Carba1984 Posted August 13 Author Report Share Posted August 13 Hi, I have been working on it for 3 hours, I have managed to make the idle not go up by cutting gasoline, I have also discovered a plug that someone has put in the vacuum feed tube of the distributor, There's no problem with the balancer 1 Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 14 Report Share Posted August 14 is this an electronic rev counter it seems too smooth/damped to be the cable driven you could be showing changes in charge voltage pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 14 Report Share Posted August 14 is the rev counter driven by a cable drive from the distributor base or is it electronic done by wires Pete Link to comment Share on other sites More sharing options...

There must be something not right with the intake/carburettor. Iain Link to comment Share on other sites More sharing options...

Carba1984 Posted August 14 Author Report Share Posted August 14 If I lower one face to each nut, the car goes wrong when I accelerate, I can't lower the idling anymore because the screws are already down from everything Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 15 Report Share Posted August 15 if you remove the oil filler cap does the idle increase ?? air leaks from the rocker box zone will have effects on your idle Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 15 Report Share Posted August 15 then the comments about electronic points and electronic tacho may well be where this nightmare of twiddling is getting its gremlin from i would refit mechanical points and test the result to eliminate this idea Pete Link to comment Share on other sites More sharing options...

Pete Lewis Posted August 16 Report Share Posted August 16 and take the rev counter impulse feed off the coil terminal . just to make sure this is not interfering might sound daft but its certainly caused upsets over the years Pete Link to comment Share on other sites More sharing options...
Carba1984 Posted August 16 Author Report Share Posted August 16 Guys, I have sprayed with spray and I have discovered that the idle speed varies when sprayed on the axes of the butterflies, I don't know if this translation is good, but I think I have my idling problem here, There's slack Link to comment Share on other sites More sharing options...
johny Posted August 16 Report Share Posted August 16 This is quite possible but there would have to be a lot of wear and movement in the butterfly spindles. Then this is would usually make the mixture weak when driving.... Link to comment Share on other sites More sharing options...
Carba1984 Posted August 16 Author Report Share Posted August 16 (edited) The car on the road behaves well, I think the problem with idle is going to be that air intake in the butterfly spindles, I don't see any other possible option. I've checked everything Edited August 16 by Carba1984 Link to comment Share on other sites More sharing options...
johny Posted August 17 Report Share Posted August 17 Can you try putting grease temporarily around the spindles where they exit the carburettor bodies to seal them and see if theres an improvement? If its definitely the problem then new spindles are available and hopefully the bodies will not need machining... 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 17 Report Share Posted August 17 just to add when fitting new shafts leave the butterfly screws loose to allow the plate to fully centralise when closed before tightening them. and be aware the plates are chamfered and must only fit one way round or you wont close the throttles Pete Link to comment Share on other sites More sharing options...
Carba1984 Posted August 17 Author Report Share Posted August 17 The plates have a small valve, I have seen that many people change them for plates without a valve.The plates have a small valve, I have seen that many people change them for plates without a valve. By the way, right now I'm idling between 900-1100 but with the screws loose from everything, Without acting on the butterflies Link to comment Share on other sites More sharing options...
johny Posted August 17 Report Share Posted August 17 yes those valves, which are to reduce emissions when closing the throttle at high speeds, can leak air through and affect the idle. As you say the butterfly plates can be replaced with solid ones or the valves even soldered closed... Link to comment Share on other sites More sharing options...
