OK the fuel distribution is the same as any other two stoke which works,from the compression of the rings.So you saying it's flooding in the front cylinder which tells me it is getting the fuel.Which doesn't sound like a problem.What sounds like the problem is,is a weak coil.Which is not uncommon with the Twins.However this would be the first one I've herd about being the front cylinder.Unless someone has changes the leads around (which really isn't that hard to do).I guess you could check the lead on a multi meter,but I can't remember what the reading would be.
Failing the leads being a problem.I'm sorry to say but it could well be the coil,they did have problems with these coils and it was always a week spark to one of the plugs.Usually the back,but I guess even though I've never herd of it could well have been the front too.
Just a pitty you weren't closer or we could try one of mine on it.
