Hi All
so....I put a set of dual ict webers on my 1600, 009 dist, elec ign. non stock exhaust. I bought these used but took them apart, cleaned and re assembled before I put on engine. The float bowl valves seemed to be operating correctly also. I have a small aux. gas container that I used to use to run motorcycles with when tuning with no gas tank. Its actually a paint gun cup with an inline filter. I was using this because the gas tank is out of the car and I wanted to set up the webers anyway. The little gas tank holds about 3-4 cups of fuel and by the time I get to the back of the car after starting it, after 30 more seconds the gas is gone. So total of about a min and 3-4 cups of fuel has been drank by the motor. The fuel pump is ok, and has a good diaphragm, so I know its not dumping it in crankcase. The jet sizes in the webers are 160, 130, and 40. I have the screws set to what weber says to start off with when tuning.
Is this normal or an excessive amount of gas to be using?
When hooked up to good size MC engines the gas would last quite a while before it ran out
Any suggestions would be welcome
TIA

I can usually fill the carburetor float bowl with maybe 4-5 ounces of fuel and get it to idle cold for maybe 30 seconds, hot it will idle for longer. |

Make sure the gasoline does not leak down overnight or even over a period of 3 days of no driving. You will need a way to measure the gas level in them. In the Thing you probably can look down the throat of the carb while it's running. You should not see gas going in when you look down it at idle even revving a little. If gas is going in then the float is too high or the needle valve is sticking or something. Check the plugs for being all carboned up. Maybe it's on one and not the other. _________________ 1960 Beetle And 1679cc DP W-100 & Dual Zeniths! |

Thanks for the responses.....turned out to be a float had a little hole in it! Got the gas out, cleaned and put a drop of solder on it and no more problem. Runs better too! Duh. |

Yes, It probably is running with a higher gas level now on the repaired float. My need the gas levels checked between carbs. _________________ 1960 Beetle And 1679cc DP W-100 & Dual Zeniths! |
