New Engine start up

[Tom Howland]

Lemans24,
Well I have the dreaded boiling gasoline. I started to do the tune with a hot engine that was turned off. I leaned over the engine to get a tool and heard the boiling. Looked down the venturies and saw the squirters squirting and drips coming out of the auxiliary venturies. Pools of gas on the butterflies.
I’m going to check the needle valves for construction debris first. Then I’ll make some spacers from 1/2 inch Lexan to curb the heat flow hopefully.

Gary,
I do have an O2 logger setup. Been waiting for 200 miles of break-in which I got Monday. Balancing is close but not final. I think mixture screws are 1 1/4 out. I'll start moving them towards 3/4. Timing is 36-38. I saw the progression holes in only one carb so I will now check all of them.

Thank you guys for the input.

be aware of cylinder wash. If your dip stick smells like gas, change your oil. I will turn the engine over a few times without starting to clear out gas that is sitting on top of the butterflys. A Porsche guy told me they sometimes put a switch to turn off the "spark" so the carbs can clear out
