Barnett Trials Posted November 12, 2018 Report Share Posted November 12, 2018 Hi there I have a Montesa 304, needing a new carb. Its fitted with an Amal - any idea what model it should be, and what alternatives are there ? cheers John Quote Link to comment Share on other sites More sharing options...
pschrauber Posted November 13, 2018 Report Share Posted November 13, 2018 (edited) Alternative could be a Dell'Orto PHBH 26 BS, the a bit more modern one with air screw and idle jet nozzle. At leat works great to my 242, another carb but expensive would be a 25mm SmartCarb* but that is costly. I would not use an AMAL again unless the slide issue is not solved, (the AMAL used the same material for carb bod and slide which causes super much friction and leads very fast to rattling slides so worn slides and carb bodies!) The silde should be made out of the softer material the Body should be made of the harder material, so the slide wears and not the carb Body, thus the plated and hardened slides are not such a good idea because in the end you will have a proper working slide but a worn out carb Body ... *SmartCarb has no jets which is super nice in handling and if you ride in very different climate and hight situations.
