Could i be having this problem if the carb is to small for the engine.We have not checked what size the engine is yet the guy who bought the carb thought it was a 1600 so he bought a carb for it for a 1600 .Now all i have to do is find the size of the engine .A friend compared his manx with an 1835 to mine and the case bolts on mine are 5/8 same as his and with a 1600 the case bolts are 9/16 does that change anything? |

| I wish I could help but I'm not mechanically inclined. If you don't get an answer here, post your question under the year VW that you have. |

You check the manifold boots for cracks? Sounds like a vacuum leak to me.

No cracks in the manifold but the rubber covers that go over the manifold and clamp down are worn out. |

Wrap them the best you can (by them I mean the rubber boots) in tape or plastic or some thing to seal the boots and see how she runs. You just want to eliminate possibilitys of a vacuum leak one by one.

I also found that the gas line was pinched and the valve was not all the way open. I will wrap them as best i can i have E6000 industrial rubberized glue i can fill in any cracks 6000 psi of pressure to break |

A pinched fuel line definitely does not help.

I hate thoughs times when it could be a multitude of things like in this case im not sure how good the fuel filter is the fuel line was pinched the valve was not open vacuum could be off.Now i have to re set the damn valve lash on this and i have no clue because im used to go kart engines not car motors my go kart engines only have two valves that are not connected. Can anyone tell me what i should be doing im on the left side of the engine what is valve one vale two valve three and 4 is it the valve closest to the driver being number 1 ? Should i be at TDC when i set valves one and 2 or BDC .I read someone mentioned model of the engine this engine is a UO model |

| Idle Cutoff Valve on the carb hooked up/functioning? Mine was not hooked up and would only idle stay running when cold. |
