cold weather troubles
I have a couple of medalists with four stroke engines that have both had the fuel pump pulse line freeze up. This causes the carts to not start. If I pull the fuel pump vacum line off I will find ice in the middle of them. This has happened when its around 0degrees or colder. Both carts are stored outside. I am sure this is just condensation but I am not sure how to fix it. Does anyone else run their carts below 0?

Re: cold weather troubles
Try a little gasline antifreeze. Run in the minus here and dont seem to have a problem. I was told alot of the water you get in your tank is from using jerry cans.

Re: cold weather troubles
But its not in the fuel, it the vacum pulse line to the crankcase. These usually start right up even at 15 below.

Re: cold weather troubles
It probably is condensation from the warm motor.. If you could get the hose where the pump and hose is higher than the pulse pick up from the motor, any water in there would go back into the motor.. Not sure if that is good either though but it would solve that issue. Also an electric pump may fix this..
Just out of curiosity, how much water are we talking about ? Option 3, put a T in the pulse hose at the low spot that goes to a piece of hose say a foot long that is below the rest of the hose and capped off. Gravity would send the water to the bogus tube that you could drain when needed.. |

Re: cold weather troubles
Thanks for the ideas. It's only a very small amount but just enough ice to plug the line. I will try raising the line to get a slope to it.

Re: cold weather troubles
I had the same problem, wouldn't restart in cold weather. I put a 7psi electric fuel pump on mine. I have the pump wired to come on with the gas pedal. In very cold weather I let the pump run a little bit without the engine cranking, it heats the fuel because the pump gets warm and that alone will get the fuel flowing

Re: cold weather troubles
I don't have any problem with mine in extreme cold. All you have to do is slope the line so it drains. I wouldn't fiddle around with electric pumps the pulse pumps work great and last a very long time. Good luck.
