    Carb Installation; help!

    I took my carbs off to clean them, and now I am trying to reinstall them on my Hawk with no luck! I bought new rubber boots and got them on the heads, but no matter how I try (and I've been trying for over a month now!), I can't get the carbs back on. I got the left one on at one time, but the right one (facing the front of the bike) was not aligned with the rubber boot at all. So I took the left side off again. I've been trying now to push down the right one, but it's just not working. Does anyone have any helpful hints? I read somewhere about twisting the carbs clockwise, but I don't really know what that means. I tried that when I had the one carb in, and there was just no good result. Do I push them down all at once or ?? I'd really appreciate any help. Thanks!

    It is a little tricky. I use some silicone spray, get them lined up, then push-twist-rock until they fall into place. Just make sure they are really lined up right first.

      I had a notion that the carb rubbers have got a bit moulded in that locates them in the right position on the stubs? Once the rubbers are correctly located you should be able to push the carbs down onto them. A bit of wd40 or some petrol on the rubbers will help.

      Although old, hardened rubber can be a real beast new ones should be easy - I wonder if something isn’t lined up. If you posted some pics that may help ?

        sometimes helps to have the boots half on/half off and angled to match up to the heads/carbs best. use dab of grease on heads and carbs too.

          Make sure the metal bands are as wide as possible and located where they should be so not in the way. I have used Armorall to make them slippering.

            I refitted my carbs yesterday. I used plumbers silicone grease to lube the rubbers just a smear so it didn't go everywhere. Also might help if the rubbers are warm and flexible I warmed mine up with a hairdryer.

            Don't try to push straight down get one side started but not all the way in, in then twist and wiggle it until the other carb is just in but don't put down pressure until both carbs are in then I rocked it backwards and forwards until the carbs slipped into place.

            You don't want to press down hard it's a softly softly Job. The only time you press down hard is when you tighten the bolts on the straps otherwise as I found they can slip out of place. Just use one hand to press down one hand to use the screwdriver and your spare hand to hold the torch so you can see what your doing.

            I found it easier to connect the choke cables before fitting the carbs the front choke isn't easy to get to.
