2 stroke surge
Hello,
I have been visiting the site for some time now. My Golf Cart will start run strong for 10 sec than bog and run slow. Once I let off the throttle for 5 sec it runs strong for 10 sec and so on. Cart was running fine when parked 6 months ago now this.This is a pre mix as the oil injection has been disabled, here is what I have done; Claned carb completely (off of cart) Replaced air cleaner replaced al fuel with fresh I would think this a fuel pump? |

Re: 2 stroke surge
Welcome. YEP sounds like the fuel pump but test it before buying a new one. On jack stands !!! remove the fuel line going to the carb and crank it see if you have a strong pulse of fuel. If you do the pump my not be the issue. Has the crank seals been replaced as any point? This could also cause a surge due to a vacuum leak because its a pulse pump.

Re: 2 stroke surge
I would check the pressure out to carb fuel line and make sure you have a strong stream.

Re: 2 stroke surge
Is the govenor still hooked up?If so,this surge,then lag is your govenor kicking in.I would look at the carb,fuel-pump,lines,filter,and crank-seals if this running problem is new,but under normal circumstances,the way you describe the power rise/fall would be the govenor kicking in and limiting power.Hope this helps.
