The Bocar 30/31 copies have a poor reputation.Several years ago a company called Brosol produced another Solex copy, the H 30/31 endorsed by Solex. I've run these carbs on 1500 and 1600sp engines for years with no problems at all. I have some NOS spares but don't really want to sell them. If you keep an eye on the forums and eBay you may be able to pick up a new one. The Solex 30 that you have is basically a good carb. With some new bushes and a couple of spacers to sort the idle cam problem, it will go on for years to come. The accelerator pump is probably fine, but could do with a new diaphragm.
