    dont open up the fuel pump. Just get a soda bottle, make a hole in the cap, attach a fuel line hose.

    Wrap the part where the hose goes through the cap with electrical tape about 20 times. This will seal it.

    Use this as your fuel source whenever you have a funny engine issue. You can't believe how much trouble comes from that fuel pump. This is the only way you will know for sure.

    My Z was doing the exact same thing and the fuel pump was working!! I thought well it pumps fuel? The fuel was not enough....just as you describe.

    If I would go 3/4 to full throttle for a length of time it would bog and act like its running out of gas. If I took the hose off while running gas would pour out...but it was not enough to feed the carb at high throttle.

    It is not bogging like it is running out of gas. It is making that crackling rich sound.

    Man,

    I am going through the same deal with my seals. All I know is that if your crank seal go out you will either have a lean condition (if the stator side goes bad) or a rich condition with alot of stinky smoke if the tranny side seal goes out.

    I don't know how to figure out if they are good or not. I know if its on the stator side you can spray WD 40 around the seal and see if revs go up.

    On the tranny side its tough to say. That does not sound like your problem though because if it was leaking it would be leaking when you rev and idle too.

    Maybe someone else has a different idea.

    hey...if you want...you can sell that trike to me so you don't have to worry about this anymore...

    For the right price anything is forsale. I tried new gas today and it is still running like crap. Ill wait entill i get the eletrical parts from blazer. I hope it is the coil or something and not anything internal.

    Granger....don't fret man. Send a PM to Tim and see what he says.

    This is a tough one but I know Tim will figure it out.

    I don't want to buy your trike...remember you told me the same thing when I was pissed off about mine....

    ...thats why I said it.

    Good luck and hang in there!!
