Typo in Subject heading: should read "Need help with Ford 2000 [b:f26a7c5a10]3cyl[/b:f26a7c5a10] gas with Holley Carb"
I just rebuilt this Holley carb, including the throttle shaft and accel. plunger. I followed Rachel's instructions from J&D productions on you tube: sanded the new plunger down til it just fit in the cylinder, etc., but I left it pretty snug.
The butterfly works freely by hand. Engine starts up and runs pretty good at idle...
THE PROBLEM is: pulling the throttle gradually as you normally would to rev it up has no effect. Pulling it half way , or even two thirds has no effect: still idles. The throttle will only open if I pull it ALL THE WAY down, then it opens wide and I have to try to regulate it by pushing half way back to idle. Very tricky!
I have checked and oiled all the throttle/gov. linkage. The springs are connected on the horizontal throttle rod and the verticle gov. lever. I suspected the governor (though it was ok before I rebuilt the carb) but the Gov. seems to respond by pushing the lever back when the carb to gov. link rod is removed, when running.
I don't want to tear into the governor, especially if the problem is with my carb rebuild, of course. There is precious little info about these governors on the web!
QUESTON: Is it possible the accel. plunger in the carb could cause this behavior if it was sticking? Or can anyone suggest something else?
THANKS IN ADVANCE for helping me out!
