sick of my 36mm drinkin fuel faster than i drink beer ,i opted for a 30mm , problem carb/manifold sizes mismatch . after stepped rubber splits an failures ,home made conversion silicon sleeves tending for carb to shift ,only a short stub on carb so tighten the clip an they squeeze off .

out with the home chemistry kit an a quick order to simply bearings .

polish out the brass bush so with heat it can be forced on ,an locks on cooling , clean carb an bush with acetone .

mix up the aliminuim epoxy resin , chemmy metal gloopy stuff , a smear round carb mouth ,making sure to fill the groove for rubber .carb 003 by henri briggs, on Flickr
heat bush to 50 celsius , slide on an seat with rubber mallet ,

check excess gloop has formed a gas tight seal around joint an leave vertical in a vice for 24 hours , stuffs quite runny an i dont want it seperating from joint .

an the final bit , collect gloop an leave to set ,so i can check its hardness an that i mixed it correctly , then pop it in the bean can with ethanol rich petrol . theres already other earlier bits been soaking for months in there , a ongoing experiment after finding jb weld dont resist modern fuel anymore .

an yes ,for a "proper job" i should of machined/re-created the grooves in outside of bush for rubber ,but there not essential . H
