Carburettor Dellorto VHST 28 BS.
The Dellorto VHST is a flat slide carburettor with an extremely small housing. Its dimensions are exactly between a PHBH and a PHBL. With its 35mm connection it has the same dimensions as the PHBH, and can therefore be mounted on all rubber connectors with this dimension without any problems. With 6mm main nozzles and D needles, Dellorto uses the standard range. Only with the mixing tubes HH and the secondary nozzles Dellorto treads a new path.
With the connection width for the air filter is 50mm.
