[ROVERNET - UK] Calling Rovernet Brain trust!!!

[Slatskars]

Ben,

Just got through double checking all of my SU reference manuals and the HD 
carb needles are set the same way as H or HS fixed needle types. Loosen the 
holding screw and use a straight edge to set the should of the needle flush 
with the bottom of the piston. Retighten the screw and it is set.

I have both the Haynes and Burlen SU workshop manuals, but can find nothing 
in either of them about this economizer valve device that John Burkhard has 
brought into the discussion. Also no mention in either the P-5 factory 
workshop manual or the Autobooks version. I am not familiar with this Wades 
book. Guess that I will have to locate one of those too. That is unless John 
can somehow scan that section onto the web site or is willing to send me a 
copy also. Very interesting. I really like his simplistic explanation of the 
operating principle. I really like the Burlen SU manual as a reference book, 
but I guess they missed that one feature.
