[AT] Need help troubleshooting engine/compressor

Sun Aug 16 20:24:41 PDT 2015

Bo:
Thanks, that is what I ended up doing..    I loosened up the spring on 
that Sullicon control some...  It was adjusted to the max.   Then I 
backed off the Pressure regulator screw.  Then I also lengthened the rod 
from the governor to the Sullicon.  The 6cyl carb I installed had the 
float hinged at the front end of the engine.  The intake manifold carb 
flange was angled to allow the carb to be horizontal when installed in a 
vehicle.  In the compressor it causes the front end to be low.  The new 
carb was flooding some due to this.    I set the float level down and 
also backed off the auto choke.  I also advanced the timing a lot.  It 
finally would start and run  enough to build up minimum pressure and cut 
back...    I ran the compressor at open discharge and it ran for a while 
then loaded up and died.   It would not start.  I checked and had no 
spark at the coil.   Installed the old coil and it ran. The new BWD $30 
coil lasted about 10 minutes...  I adjusted the compressor to run at 
90-100 psi when blowing through a 1/2 inch hose barb.  I have a claw 
foot hose barb end that connects to a 4 ft length of pipe with a valve 
that I blow off the equipment with.  I think it will improve with 
running, I still have to make an adapter to fit the air horn of the carb...

Now if I could just get the Leroi running.  I got a 60cc syringe and put 
60cc of SiliKroil in each cylinder.    It may not do much for the 
valves, but it will loosen any rings that are stuck...

Thanks for your advice...
