[QUOTE="Big Sid, post: 37673, member: 2781"] On Lola , our twin racer . It uses 32 mm concentric Mk 1 carbs , these the new production carbs currently being produced . Much improved over the earlier ones , better metal and precision casting throughout . But where the old ones had a simple loose fitting tickler button projecting up out of a opening , this serving also as the vent hole for the float bowl , now there is a more sleek alloy tube standing proud capped snugly by a hood . This certainly keeps out rain and dirt but it's all so close fitting that it nearly seals out air from entering , barely any can be sucked through . While there is a small hole in the vertical tube it is closely covered by the sliding hood . This has to be a problem if one uses full throttle running hard through the gears and the fuel needs to be exiting the bowl right now . Certainly a poorly thought out modification of the original venting provision . I have drilled right down through the hood cap exposing the hollow tickler shaft which should eliminate the problem . I had talked over my concern with Tom Healey who suggested the course of action . Tom is a clever fellow , a real asset to Coventry Spares and his Dad John Healy who is a carburetion whiz . Sid .
