Webra bubble boys

[Gray E Fowler]

Guys....

Do what Lance said...Back off the pump pressure. Both Lance and I flew the 
Webra/Bully for years and every single one of them required a lower pump 
pressure than how it was set from the factory. You will know that you have 
too low of a pressure when you can open the needle valve all the way and 
there is no change. Get there and then increase it a bit. Once you get 
that set you will find that you can adjust the low end needle to do what 
it was supposed to do...adjust the idle not the mid range.  The engine 
does not require alot of pressure to operate.....just enough to get it to 
the carb.
