had suggestions about what carb to fit delorto seems to be the most popular anyone got one fitted and how do the get on with it.or are there any suggestions

the choice boils down to amal concentric or dell ortto frankly many critsie the amal and change thier dellorttos for the scottish/ looking ta the scottish results though the amal cant be that bad if after two days of the hardest pre 65 sections you only drop 3! now that UPB and Armac have the stuff off the shelf then frankly its down to personal preference and for what and where you'll use the thing. the amal will get you in every club trial in the country the dell orrtto will give you some restrictions.. ( but not many..)

you should also consider that the dellorto is easy to install (one piece rubber manifold from Armac or 3 piece from UPB) easy to set up, doesn't need constant adjustment,seems not to wear out to quickly and in some cases seems to use a lot less fuel.......

Most of the guys seem to swap back to the dellorto after Scotland.

Del-Orto all the way unless you intend to ride the SSDT P65 trial, fit one & forget it they are perfect for the Cub.

Who are UPB?

http://www.upbuk.co.uk/pre65.html in the interests of fiarness other suppliers are available.. but not on my favourites list!

any idea on size or model. thanks

Hi, Don Smith and a few others were playing around with the Villiers carb to good effect.It seemed to work well, the only downside is the lack of an idle screw, in its original application the idle speed was set by adjusting the throttle cable. This can be overcome with a little engineering, and as far as Iknow Don never had a problem with entries, due to the carb being British. You will have to make an adaptor because the carb is a stub fitting. If anyone is interested to try it, let me know and we can see about making the adaptor. Dave
