    Hello

    I am the new owner of a 1975 175 Cross Country GP. This is my first foray into the world of vintage bikes. When I turn on the fuel and kick it, after 3-4 kicks, I will have a torrent of fuel leaking from where the exhuast pipe joins the cylinder. I will take out the spark plug remove the pipe, let it dry out a few days then change the gearbox/crankcase oil.

    I have also dismantled the carberator, and examind the float which seems to work fine, I dont know if the needle is seating properly or not, but the mechanism seems to be free moving and not stuck. It is equipped with an Amal 32 mm center float chamber carb (mark II).

    I've done this drill 3 times with the same result. Anybody ever dealt with this or have any helpful ideas? I've thought of switching over to a mikuni, but don't have any info on what model to get. Also, this may seem like a dumb question: what constitutes a right vs. left carb?

    Unless you have bad main seals, your transmission oil should be alright. You can remove most of the fuel mix from your crank case by kicking the motor over a bunch of times with the spark plug removed. Check your float level for proper height and make sure it isn't installed upside down, your float needle for wear. The needle should not have a groove running around it where it seats. If those look good, check your float chambers for leaks by taking the float assembly out of your carb and submerging it in a bowl of warm water. Any holes or cracks will immediately show up as a stream of tiny air bubbles.

    The difference between a left carb and a right carb is the side the tickler is on. They use Amals on Triumphs,and other British bikes of the 60's and 70's some had dual carbs, mine has a single with the tickler on the right side because the exhaust pipes are on the left just like your husky. It is an easy carb to set up.

    not too familiar with amal carbs, but the symptoms you are describing usually result from a worn needle valve. it might look alright, buy if the needle valve doesn't seat properly it doesn't matter where your floats are set. they are cheap, and easy to replace. try http://www.speedandsport.com/ i believe they carry parts for amal carbs. good luck to ya.

    If you do change the valve make sure you check your float level before and after you change it.If you have the plastic needle valve and you replace it with the Viton tipped brass one you may have to change the float level

    I have a 76 175 CC as well. I had issues with the Amal that were similar. What I did was put on a Mikuni. Wow what a difference. Starts 2nd kick when cold and 1/2 when warm. Great throttle responce as well and idles like a dream.

    As stated before I believe speed sport carries Amal parts but i have not ordered from them.

    I used the 32MM v Mikuni and it is a dirct bolt on. I lowered the clip to the 3 notch from the bottom and adjusted the air screw to 1 1/2 turn and plug reading is great.
