430 fuel throttle

DanMN · May 15, 2019

430 sat outside 2 years- got running but it only goes one speed- shifts runs fine but you can see the lever go back and forth on the pump but doesnt go any slower or faster- thinking governor seal in pump- would like some other thoughts before taking pump off- diesel with a roosa master pump

I would take the top off the pump and manually move the governor mechanism, it sounds to me like the linkage must have rusted or varnished fast, I believe if it was rust it would have destroyed the head so if it is rust consider yourself lucky, Im betting it will free up with a little movement, there is nothing loose in there that will jump out, take care with the cover screws as I have seen them twist off, I would put good penetrating oil on them then take a punch and hammer and TAP on them a few times to help loosen them up. You will probably fix it that way, good luck, keep us posted,
