[C320-list] ENGINE FUEL PRIME

[Joe Jablonowski]

 Have you ever checked inside the exhaust mixing elbow?On my Perkins Perama diesel, the massive iron casting looked fine from the outside, but the internal rust had choked the system badly. The normally 1-1/2 in. dia. aperture had narrowed down to 1/4 in.!- Joe JablonowskiC320 #104

 I just got on here and noticed this thread. After a perfect season last
year, my Perkins Perama engine would not start this year. I changed the
Racor and on-engine fuel filter, bled the system (which had a lot of air in
it), and finally got it to start. Now it will only start after using glow
plugs for 30 seconds, setting the engine on full throttle and continuous
cranking for nearly 30 seconds. We have since changed the fuel and return
lines. still the same result. Once started and shut down, it will
immediately start again, but as soon as the engine has cooled down,I have
to go through the same process again. Once it starts, it runs great,
unloaded or loaded. Any help would be greatly appreciated.
