There is a small restrictor (part no. ETC6243) in the fuel line between the vapour separator and the Weber carb on a 110 2.5l petrol. Do you have one of these or can you tell me how big the hole is in it please? (The restrictor from the parts book only looks about 6mm dia x 6mm long with a small hole through it and it just sits in the feed pipe.) Thanks for any help. Regards, Seaboy
