mine has got 4gals on it now. and i have never had a leak yet. how much fuel does the motor have one it? i know the front bearing can seep fuel if ran really rich. if the carb retainer screw is leaking put some rv silicone on it and it should take care of that. may want to check and make sure the screw isn't loose.

Does your carb retainer have any o-rings on it? If I'm not mistaken, there were two versions of the carb retainer.

Those prices cannot be with any Mods. Thats street price for the stock P/S/R
The seller hasn't responded to my question, so I think there's no mods other than being a Arrow set (which changes the rod design).... but even if there were mods, I wouldn't chance it. What credentials does that guy have?

My motor has about 2-3 litres on it and i did find the screw a little lose so hopefuly that was the problem but one thing it held it's tune all day and the seeping could be from that as there was minimal dirt on the bearing only on the bottom...

The only part that will fit an xz-b is the rod. Everything will fit a vz-b though.

Yes,The pre-run version can save you time of break in,it has been run in at break in stand for few tanks with a break in fuel.
