I was planning on running them withut the choke flap as I mostly drive short journeys, and at the moment I've got the choke mechys completely disabled and starting isn't too bad. I worry about all that extra richness everytime I stop for 10 mins and then start again! The extra throttle lift would be usefull though. > sounds like these carbs have been rebushed previously as ive never seen > any from the factory that had any form of bushings in them the spindles > allways run in the housing. I think it must have been a VW approved dealer refurbishment as they are so identical, and I pulled one of the PTFE liners out and the machining is beautiful- too good I think for a home job by most. > having fitted at some point all the jets available in my carbs ive ended on > 132.5 mains as the most power producing jets my mpg on a long run is about > 28/30. Aren't you running a bigger setup though Neil? Mines stock 1600, and at the moment I'm still only getting avg 20mpg- hence the need for rebuilt carbs. I think I'll try the larger jets on the left bank- I'm sure this would help the longevity of the engine, and its hardly up to modern emmissions standards anyway so a little worse won't hurt too much, and there are few enough of us anyway! Besides, if the engine stays in better condition for longer as a result, thats got to be better for everyone, init? I also need to take another look at the ps&cs this summer and maybe replace them though they looked very unworn last tiime I looked. Somethings not right ;-( >because the idle neadle is finer it will give you better adjustment. How many turns do you have to screw the adjuster out Neil? If its about 3, does that mean that it should be screwed out 1/2 to 1 turn past the point where the engine just stops faltering ( instead of 1/4 to 1/2 for the earlier coarse thread as per Haynes)? > best o luck. Thanks Neil, I think I need it. Its really encouraging though that these carbs are so simple. I likes simple me! The carb on my Citroen Dyane was way more complicated with dual chokes and all sorts of linkages- that was only for a 600cc engine- albeit a higher tuned engine than ours- it would sing at 6-7000 RPM all day in stock form! A pig to work on though compared to my Type3. Mark Seaton '73 TA ------------------------------------------------------------------- Search old messages on the Web!
