670cc full throttle

[ROLY239]

My 670cc predator engine starts at full thottle every time I turn it on, only time it seems to be on lower revs is when it’s in choke. I’ve removed the governor too I don’t know if this has anything to do with it.

Check the throttle cable and where it connects to the carb... It might be pulling a bit, therefor taking off on you...

I agree with mckutzy, but another possibility is your Engine was made for a special purpose; like on a Generator... The Carburetor on Generator engines are different, It's completely normal for them to run at high RPM all the time, and never be able to Idle down until the Carburetor is replaced or possibly modified...

Did your engine used to start at full throttle every time, before you removed the Governor?

Lets see some pics of the throttle setup...

I'm pretty sure carsandcameras had this problem because the motor used the governor as a return spring of sorts. Add one and see if the problem goes away.

Kinda how a small block clone works..
