Thanks Richard,I already have a spacer from Triumph Tune which I will be replacing with the new one.

Well after some surfing I have found that Minispares suppy a carb spacer fitted with a vacuum take off,so all problems solved,

I have a GT6/3 with twin HIF6 carbs and I'm intending to drill and tap the manifold in order to use twin gauges to balance the carbs. 1. has anyone done this? 2 how close does the water cooling part of the manifold come to the flange,looks a good place to drill. 3 I would much prefer to acquire the small tube the same as the vacuum advance fixture on the rear carb,is that possible? 4 how important is the diameter of the hole into the inlet tract? Please don't tell me to use a tube to listen to the hiss,tried that ,can't crack it.

Fastyr mie,or good evening Vanadium 23, not bad for a stopover! .Thanks for the info,well worth looking into should this horror crop up again.I've always drained my bikes in the 'off season' but have so far got away with it on my mower. I've been dormant for a while on the forum, not really a newbie ,been a member for 27 years.

I considered drain cleaner but locally it comes as gel in 500ml bottles not practical to circulate around the tank. So plan B caustic soda,I added 500gms to 5 litres of water threw a few stones into the tank and agigated it for about 10 mins. and when it had cooled down about another 10 mins emptied it into 25lt old water carrier for later disposal at our local centre(hope they take it) Repeated the procedure and now the tank is really clean inside. On each treatment I thoroughly rinsed it with water to stop any future corrosive action. If you decide to try this wear protective clothing,gloves and eye protection.

Thanks for the link,the tank out of the GT6 mk 3,the deposit is black and gooey .This after 12months off the road . I'll try new petrol when I have unblocked the outlet,it really is quite a mess.

Can anyone recommend a suitable method of getting rid of the black goo left in my tank by stale fuel. Ta
