JCB 214E idles but won't answer throttle.

2007 JCB 214E 1000hrs. on the meter. been chasing an air leak (if tractor sits for a week you have to pump the fuel filter a couple of times at startup) tightening fittings one at a time and THOUGHT it was resolved. started it yesterday and it revved to approx. 1800 rpm (butt puckering moment) then settled down to idle. but all it will do is idle. won't answer accelerator or hand throttle. traced out cables to pump and they are free. injection pump lever moves shaft on pump but idle speed never changes. fuel filter is new. screen is clear in tank. fuel starved somehow? if it idles can I assume the fuel solenoid is working and it is getting fuel? what am i missing? pulling that pump is gonna suck......... any thoughts will be appreciated.

That implies the engine was running.... so that makes me bow out without a clue. Mine (1550B) wouldn't change RPM once and it turned out my throttle cable was fraying/stretching inside the sheath. Replaced it and all was fine. It would however, change speed if manually forced at the pump.

Good luck with figuring it out and fixing it.

Google is your friend on this one.. theres a lot of variables to this problem..
But if u go to google & type in, "JCB 241E injection pump".. theres a thread on TBN exactly like your problem & all the diagnostics associated w/ it.. AND the cure..
Good luck & let us know how you made out..
Pulling the pump is easy..

THATS "ion" pump.. NOT "or" pump.!!!

searched TBN directly for "JCB 241E injection pump" as well as "JCB 214E injection pump" and came up with nothing. ditto for broader spectrum searches with different S/Es. I will be happy to read, research and rectify my tractor problem if you would point me @ the thread that is "exactly like my problem"........thx in advance.

I was mistaken.. its on the Yesterdays Tractor thread.. found it using google.
