  1. These days I keep asking myself how do tin top manufactures get 50 + mpg from a car that will do120 mph ??? they all seem to do it now ?

     

    It is because the engine wasn't designed 40 years ago!

  2. Hi Paolow the reason we ask where you live (if you haven't put it in your details) is that there is often someone nearby who could help or at least pop around to drink your tea and commiserate. Glad you have got it running ok, going any bigger on main jets will just be a waste of fuel on a std. pinto I would say. I have a dgas with a reasonable cam and flowed head with 137 jets and that is slightly rich according to my exhaust pipe colour. As for timing that has been a popular topic recently try a search on here but at tick over with the vacuum advance disconnected (and blocked off) start at 8° btdc. As for the surge it sounds as there may still be a bit of an air leak somewhere, also check that both butterflys fully close together. sometimes they get out of sinc there is an adjustment on one of the gear quadrants to do this.

  3. The Stevenage group were invited, at short notice! to join local Westfield owners for a trip to the De Havilland heritage centre (London Colney) on sunday. We had a run from Knebworth to the museum in convoy, only lost one westfield on the way. The place is very interesting, run by volunteers, no funding and has a wide collection of planes from assorted moths, a Rapide being rebuilt, Autogiro, Mosquitoes, Doves, Venoms, Vixen. The Comet fuselage used to discover metal fatigue, lots of engines from gipsies to merlins, jets and even a rocket. The people there were full of information and keen to know about our cars. here are a couple of pics.

  4. 140s are possibly too big for a std pinto so if it is running lean then the jets are not the problem. unless they are blocked. Is the fuel level ok in the carb? is the fuel pump working ok? have you tried it on a std. carb? where do you live?

  5. Once upon a time I 3/4 built a special body on a Ruby chassis and drove it along the handy farm track next door. The brakes were hopeless even though I spent a lot of time trying to set them up and the clutch was either in or out. As you say Terry how people manage to drive them in modern traffic beats me.

  6. Sean, can't be of too much help I am afraid as I have the Bosch pointless system but have you disconnected the vacuum advance when you set it at tickover? if not you will get too much advance. The Setting should be about 6° but will probably be fine at 8 or even more. The only reason I can think of running it at 2000 would be to check that the advance system is working. Good luck with the mot! :)

  7. Hi Neil, the problem with a low ratio diff is that first gear becomes very 'short' great for towing heavy things but you have to change up quicker. So it may not necessarily improve acceleration times. I have a 3.77 diff and often use 2nd to pull away, first just seems a bit too low.

  8. If the thread is unlubricated a lot of the tightening force is used up by friction in the assembly. When it is lubricated the friction reduces dramatically so the force tightens the thread as opposed to just overcoming the friction.
