I am renovating a Seeley TL200E and need to source a carburetor float chamber gasket. The carb is a Keihin marked F4 04C. Anyone any experience or suggestions on this or even replacement carb please. Main Honda dealers claimed to have a fiche but the gasket set was wrong, as were the fork seals (now sorted).

Not sure of the data precisely, however after researching my Keihin Seeley carb (same model number)I am led to believe it might be from an earlier TL 125 ('D' or 'S'). Parts for these are readily available so you should be able to get the gasket you require. I bought two jets recently that certainly fit as I am having a difficult time with my Seeley as I try and make the bike run smoothly. It seems to be very lumpy and I've relaced a 1.10 main jet with a .92 and .38 pilot jet yet the bike is still very eratic. Any feedback on what jets are in yours would help.
