[NSRCA-discussion] Fuel Regulation in 2C Engines

[Rcmaster199 at aol.com]

The Perry pumper carb has sweet running characteristics with either the  
Perry pump or webra pump feeding it. I ran it in a webra 145 for about 50  flights 
and it worked well in the metering department. 
 
I was not terribly happy with the stickiness of the barrel in the plastic  
case however, and stopped using it. To get the carb tight enough in the  
crankcase throat, I had to snug it down far enough where the plastic carb  housing 
distrorted. 
 
The same guts with an ally case would alleviate the sticky distortion  
problem of the Perry pumper carb. I talked with Conley about the problem and was  
told he was going to look into it but I guess he didn't. The carb design fits my 
 requirements of KISS and would otherwise be excellent for our application

One point of interest here and it hasn't been  mentioned in any of the other 
posts.  It would be best to run the Perry  Carb when using the Perry pump.  I 
tried this on the ST2300 and it would  not work with the stock carb.  
Installed the large bore Perry carb and  once the needle was set it was fire it up and 
fly and a very reliable  setup.   I would check to see if there is a carb 
available for the  OS 1.60 and concider this since its not worth the time and 
frustration(carb  cost is well worth it).   I now run that ST2300 in a Funtana 
and I  never touch the needle setting, amazingly the engine has the original 
bearing  and ring and it has well over 450 flights on it.
