I have a moki 1.8 with a cline regulator...........pressurized system

the diaphram was replaced 18 months ago..........5 flights on the replacement

the motor was moth balled, but started right up after sitting all this time

5 minutes into the run the motor shuts down

now it doesn't draw fuel.....except with the carb wide open and my finger over the throat of the carb for priming

could the diaphram have died already????

any help is always appreciated

Sounds like a bad diaphram to me. Take it apart again and see. Could also be junk in the needle valve. Take the carb off and take the needle valve out. Check the carb for junk.

try running it bypassing the cline, this will tell if its the cline or carb

Phantom, this thread might be helpful to you http://www.rcuniverse.com/forum/m_34...tm.htm#3490466

Call Jim Cline, he's very helpful.

Is your tank buldging out really good and reaching a healthy pressure? It's hard to draw fuel without good pressure in the tank.

You can suck fuel out of the regulator using a fill pump but first make sure the tank is pressurized. The idea of running without the Cline is good but if the tank is too far back, and you go flying that way, it could lean out in uplines. It will rule out the carb if it runs without the Cline so it's its a very good test.

WOW......

what a wealth of help............don't know who to thank first

Rajul.........the link to the other thread helped a lot, seems this item has been disected by the best.

got to believe that its the diaphram..........seems that the life of it all depends, but it doesn't seem too long with glow fuel

Joe........will be calling cline today to get model of kit needed.......thanks

I'll let you guys know how I make out...............

thanks again
