You shold have the spacers or you may run into perculation.
The Problem is caused by volatility of modern fuel. The gasoline is heated by the latent heat of the engine, and percolates the fuel from the bowl into the throttle area, forming a mixture that is too rich to fire.
I had this problem -not as usual - at hot starting but even on long Autobahn trips during summer.
When we drove down to Italy it starts running ultra rich till an state to absolute undrivable.
I blamed it on everything but the kitchen sink and it took quite a while to find out what it was.
I usualy ask some "old hands" but in this case they couldn´t help because the gas was way better back than so they never run in this kind of problems, caused by modern fuels.
..live and learn :rolleyes:
