Re: Carb removal/overhaul/refit
hi you can buy manuals from leisure trail for about £8 i think. but you dont need one. its really easy to clean out the carb. all the screws only go in one place and there isnt much to them.
all you need to do is loosen the two clamps on the inlet manifolds (carefull with the mailifolds thouse bits of rubber pipe are not as cheap as you think) and take off the overflow tubes. then just unscrew the top and take out the slide assembly.try to keep it as one unit and carefull with the needle. then all you do is:
unscrew the 4 bolts on the bottom of the carb (float bowl).
you will then see the plastic float
remove the pin holding it in place (float pivot pin)
you will see a little pointy weight hanging off it. (float needle) check that it goes to a point and isnt flat. if its flat buy a new one.
after the float and needle are removed you can then unscrew the biggish brass bolts out of the centre (there your jets)
soak the brass parts and the float needle in carb cleaner and leave to soak
there is also 2 screws on the side of the carb (idle ajuster and mixture screw) these both need to be removed as they have little rubber orings on them that the carb cleaner will eat away at. before you remove the small brass screw (mixture screw) it is very important to count how many turns out the screw is otherwise you might not get the carb setting right again afterwards. its usally about 1 1/4 turns out. so turn the screw in untill it bottoms out counting how many turns it goes but DONT OVERTIGHTEN IT.
check the rubber orings and if broken,stretched, or brittle replace with new ones
now get some carb cleaner and spray it down every nuck and cranny and leave to soak
put more carb cleaner in and blow out with some air. a pump will do but compressed air is better. if not just wipe the carb cleaner off the best you can and let it dry
give it a really good scrub where the throttle slide went in the top with a cloth.(even if it looks clean youll be suprised how much muck comes off the side). also clean the float bowl.
make sure the jets youve been soaking to one side are clean and that you can see right through them
small jet (pilot jet)
big one (mail jet)
it might sound like theres loads to do but really its pretty easy considering how much garages charge to do it.
you should find the cleaning will give you better idle and smoother running.
