porsche 930 weak spark??

[minirally]

hello guys,really enjoy the forum. now,i have a problem!

last week i go on the track with the 930,all great until i began to be low on gas,so i return to the pit slowly, for not melting somewhat.

i put new race gas,but after that,car is very difficult to start,and not working on all cylinders for sure.

i removed spark plug,and three of them are fouling,i clean them,and after that it still very hard to stard,just like a fouling engine,but finished to start after very long starting.

after,several check, i see the spark are very weak,maybe my cause of fouling plugs.

my question is,what it happens,car run like the hell before running out of gas? i have compression,is there a protection device on this car?

thanks all

ps sorry for my poor english,i,m from quebec,canada

i finally found problem, the warm up regulators faulty, they dump lot of fuel in the intake! happy,it is not the engine!!

thanks guys, run like new now.... i took the warm up from my old 2,7 engine (from the white 911)and hopefully,it is the same number stamp on it !

Was this 2.7L engine normally aspirated? If so the WUR does not have a boost enrichment circuit and should not be used.

Beautiful car!

thanks Brian, it is the same wur,same number stamped, with one small vaccum and the large one for the boost from the throttle body.
it is ok? you think.
