Simon https://vintagebikemagazine.com/technical-articles/amal/ " A note about slides: The is a lot of folklore about the slide clearance in Amal carburetors. To insure the slide will not stick in the bore from the mounting hardware being over tightened the slides are given .0035″ to .004″ clear...

Well the amount of distortion and metal removal is very small and round unworn slides display no movement in any radial axis. Worn slides unfortunately do and are a waste of time, but the result is a serviceable body. The 0.004" clearance was a revised increased clearance as users were distorti...

Better finish too!

Paul there seems to be an awful lot of oil getting down the stem and onto the valve, Fours are not my territory at all, but on the KH i restricted the oil flow to the top end by feeding it off the return and use cast iron guides which presumably run less hot clearance. The high temperature cooking p...

On attempting to assemble a pile of monobloc parts into a 1 inch body for the KH I found that the various condition slides I had were too tight a fit, due I expect to distortion of the body due to overtightening, A one and five sixteenth second hand machine reamer from ebay held in a vice with the j...

Steve, yes all cleaned out, I expect its old baked on stuff in oilways that the detergent in he oil has lifted

My KH always seemed to have an oil drip when returned from a run out with no obvious source, but when recently running it on the centre stand it became a positive drip from the oil return union on the crank case. I thought the solution was obvious and easy and tightened the pipe nut, at which' the p...

Thanks for the good wishes folks, just time to sort now, probably ok for the winter!

Thanks Paul fortunately damage to the bike is very light, mainly a bent footrest and mashed footrest rubber!

JB weld is well worth a try I think as there will be no possibility of distortion an the rough surface should provide a good key
