RF_R_US Once you had the carb apart, I would have changed the float needle. The rubber tips (or maybe your's is brass) can look fine but it doesn't take a lot of wear for fuel to flow past them. The best solution if you have a brass needle is to replace the seat AND the needle. If your needle is a rubber tipped item, the seats are usually fine and just a float needle replacement is good to go. Even though your fuel may not appear to be leaking right now, you might find that it floods the engine when driving down the road. If it starts missing or stahls, your plug could be fouled or then there is the filter starving it. If you have this problem, pull the plug and you'll know flooded or starved is pretty obvious.

BIGIRON What TOBJ said about the filter. The smaller diameter of the inlet/outlet of the filter will act as a "choke" (not like the choke on an engine, but like the choke on a pipeline). Liquid can only flow as fast as the smallest diameter of line will let it.

But there's several guys, DX and I think Paper, who run filters with no problem.

theotherbigjoe You may run into a loss of fuel issue at higher running rpms on the road.
There have been problems in the past with a filter restricting just enough fuel flow to cause the Carb to run out quicker then the tank can supply.

Heads up for that..

uk shanuss i replaced the diaphram and the gaskets in the petcock and stripped the carb, cleaned it etc.. job done. i was left scratching my head for a while with the pitcock though. i also fitted an inline gas filter as it was letting through crud from the bottom of the tank.
