beanpoleuk Posted December 12, 2013 Share Posted December 12, 2013 The Solex B30PSEI is playing up on my 1250 and needs repair/overhaul..Should I go to the trouble of repairing/overhauling or replace altogether with something else ?I would replace it with another B30PSEI if I could find one at a reasonable price, but wondered if I would bebetter off looking at something different altogether ?Steve Quote Link to comment Share on other sites More sharing options...
herald948 Posted December 13, 2013 Share Posted December 13, 2013 What sort(s) of problem(s) are you having? These carbs often respond amazingly well to no more than careful cleaning of the various jets, particularly the idle jet and the accelerator ("gooseneck") jet.

beanpoleuk Posted December 13, 2013 Author Share Posted December 13, 2013 The previous owner made one carb out of 2, but I am not convinced it has been put together correctly, the tick over adjustment screw is so far away from the stop it doesn't do anythijng, and the throttle need 'blipping' to return to a slow tick over otherwise it is about 2500 revs !

nicmk1est Posted December 13, 2013 Share Posted December 13, 2013 sounds like nothing is line up properly,,,needle not square to housing,,,5/8th spanner,un-do the housing few turns,lift pot-lift and drop few times then tighten up housing,lift and drop pot few times just to make sure it free to move without catching Quote Link to comment Share on other sites More sharing options...
Casper Posted December 13, 2013 Share Posted December 13, 2013 This may be useful:Initial SettingsAdjust the throttle/choke inter-connecting rod by inserting a length of 0.027†(0.7mm) wire, or a No. 71 drill between the throttle butterfly and the bore of the carb. body. With the choke fully closed, tighten the rod adjusting screw.Set the idle screw to just touch the throttle lever, then turn it in 1.5 turns Screw the mixture screw in ‘till it just stops, then back it out 2 turns. This is a good starting point.Set idle to 500 rpm (quite slow). Unscrew mixture screw ‘till it hunts, then screw in to give a best idle. Slow the idle down again if this speeds thing up, and re adjust the mixture again.C. Quote Link to comment Share on other sites More sharing options...
