[SEL] Webster type 1A

[Craig Buzzell]

Hello List; I am looking for info on the Type 1A Webster. I have one  
on my newly acquired Monarch Model N. It seems to be hot as I got a  
good pop on ether as the fuel is not hooked up yet. The cam  & exhaust  
valve trip rod does not go all the way back by itself so as I pull it  
over the mag trip mechanism does not engage. Am I missing a return  
spring or is it an adjustment issue?
My Economy's and Stover have a return spring on the shaft but this  
shaft is rectangular and does not seem compatible with a round coil  
spring.
Thanks for your help;
