We have fire in the hole! Tonight I managed to start her again after beginning of restoration 14 months ago, very pleased! Only thing is, she ran or carburattor cleaner, not petrol:) I could see the fuel pump was trying to but just didnt get filled. Do you need to prime it or something? I took the glass off and poured some petrol in it but that did not seem to make a difference. I also filled up the float in the carburattor to no avail. I had a 2 meter long hose going into a jerrycan which was approximatly 1 meter higher than the engine. Is there something I am doing wrong? Thanks guys, chuffed restourateur:) |

Check your pump and make sure its pumping. remove the line at the carb, place it in a small can and have someone turn her over - gas = pump is good - no gas = not so good. A good pump should self prime. You may want to lower the temp fuel tank. |

Thanks Ratchet, I will lower the jerrycan thats a good idea, I though gravity might help but maybe not.... The glas bowl is empty and stays emtpy, it should fill up shouldnt it? I do however see some mist showing up at beats which makes me think she is trying? |

The very first time I tried to fire mine up I *ahem....* had the fuel lines hooked up backwards at the pump. If you're not getting fuel into the pump, it's something from your pump back to your fuel source. Blockage in the line from the jerry can maybe? When I ran mine on an external fuel source, I used an outboard motor fuel tank and had it sitting on top of the cowl and it worked fine. The glass bowl should have some fuel in it at least. Been awhile since I had a glass bowl pump on mine, but I seem to remember it being at least half full most of the time. Good luck! I hope you get her fired up soon! |

Hmmm still no go. 1) I found out the fuel line from jerrycan to fuelpump was blocked. I will make a new one tomorrow (was going to do that anyways). 2) I pulled the fuel pump apart, well took the head off and checked the valves. They were new as I just reconditioned the pump, but VERY stiff. So blowing hardly let anythiing through, sucking was a bit better, but not a lot. So I placed the old ones back in again which seemed to improve the situation a bit. With the bowl on top I can blow hard and just the tiniest amount of air going through, sucking none what so ever. Thats for the inlet off course, the outlet is the other way arround off course:) I ran the engine and the membrane happily goes up and down. So I re-installed the top and the glass bowl expecting good results.... not. When I run the engine on the starter motor and hold my finger before "In" the faintest kind off sort off air is requested. Out is nothing at all. My question is, should I be clearly feeling a sucking and/or a blowing when the engine runs on the starter motor? Thanks guys If this aint working I'll probably order a new one, I just like to get the original working if possible... |

No ! http://z4.invisionfree.com/CJ3B_Bulletin_B...?showtopic=4289 No but you should check level of fuel in the carburetor to verify if the well has filled to proper level. No fuel should flow if the well is full. Yes but the suction is only about lung pressure or roughly 3-1/2 PSI. |

You guys rock!!!! She is running again!!! ![]() I did a couple of things: 1) Replaced the valves in the fuel pump with the old one 2) Sawn off the inlet tube as that was blocked 3) Poured some petrol in the fuel pump to get her going 4) Poured some petrol in the carburettor bowl 5) Poured some petrol in the carby to get her kicking over 6) Sanded the bottom of the top half of the fuel pump a bit more flat She is running like a beauty now!!! Thanks so much, I'll play a bit with the timing and carby settings this weekend and than its probably on to body work, exciting!!! |
