free revving sd33

Post by Wish I had coils »

A little help would be good just took sd33 motor out of smashed mud runner bolted into new body, after much bleeding we got it started, but when she started she went into self distruct mod revving her brains out.
She has no throttle responce at all just revs till i pull the fuel cut out

Sounds like you have a pump problem. There is no governor control inside it, generally from something not moving freely inside. Do you have another pump to try on it?

they are vacuum opperated govenor if you have the two vacuum hoses on the back of the pump crossed it will cause full revs or make sure the line is coming from the vacuum side of ur intake manifold
