    From memory I think you can do the mains, airs, pump and the idle. With the idle I think you can change a 50 F8 to a 55 F8 but not to a 50 F9. Not sure though on that one though.

     

    Years ago while I was at college I had access to a rolling road. I spent many happy hours *wink* *wink* fettling the old lancia, modifying the carbs as the engine had various bits bolted on it. On one occasion I put a new exhaust on it and the carb settings became way out (I seem to remember I got 15 BHP from just bolting on the exhaust 😬 😬)

     

    I drilled out the jets to suit but went a bit too far with the mains… Not having access to a supply of trial jets, I soldered the hole up and drilled them a bit smaller! I replaced them with the correct size after though….

  2. For the jets, why not drill them out? A 45 pump jet has a 0.45mm hole and a 165 main has a 0.65 hole….

     

    You can buy a set of metric micro drills for around £4 that will do the whole range. There are some on Ebay at the moment, type in micro drill, loads on there.

     

    If you use a small chuck or better still a pin vice you can twist the drills through by hand. I always file the number off the jet though to save confusion later!

     

    I used to run a Lancia twincam with 45’s on, but I found that number 1 plug was always black when the others were a nice chocolate brown… I tried for ages to find the reason why, in the end I realised that one of the jets was several sizes bigger than the size stamped on it! Looks like someone had done the trick above!

     

     

    In the past I have also increased the size of chokes on the lathe. If you do this however it’s important to keep the exact profile of the hole, including the taper and the radius. It’s not that simple a job as the hole is not parallel.

    I never liked the throttle action on my car and spent some time modifying it. One of the things I changed was the bit where your foot rests. I kept the circle but made up a new bit that fitted inside and swivelled so that the new pedal bit was able to be kept parallel to your foot. Worked a treat. *thumbup*

  4. Difficult one….

     

    The problem with the reverse type easy outs is that they expand the stud un the hole, making it hard to get out! I have never had any success with them… the straight fluted ones are better. Problem now is that the easy out is VERY hard and will be impossible to drill…

     

    I have a couple of suggestions though…. First, try using a cutting disk in a dremel to cut a slot in the easy out and then turn it to remove it?

     

    The other way I have had some success with is to put a nut over the top of the broken stud and use a stick welder to tack the nut to the stud. The heat from the weld often helps. I used the method last year to remove a broken tap from a Suzuki engine case, came out a treat!

     

    Good luck!
