jimsshed Posted February 3, 2007 Report Share Posted February 3, 2007 I think you mean you have a Beta 50 Mini-trial, not a Rev-50 (which has a clutch and manual gearbox). There is no air screw, and you will find that this carb, with it's plastic slide and single jet (yep, there's no pilot jet either) is a cheaper item than you'll find on most lawn mowers and something Beta should be ashamed of.

bob Posted February 3, 2007 Report Share Posted February 3, 2007 The carb is a cheaper item, and although I've never been inside one I expect the mixture can be adjusted by moving the needle up and down in relation to the slider. The UK beta importer 'John Lampkin Imports' will stock all parts, and might even have some upgrade carbs or carb parts. Also on their website is a map locating all the UK beta dealers if you want to stay local. You can find them at - http://www.beta-uk.com/ Bob Quote Link to comment Share on other sites More sharing options...
