Hi

I am currently running in a tup12....and while i was on the 6th tank... there was a weird sound coming from the engine.....when i checked it out i found the spring was broken that holds the header........it could be the rattling sound........ second thing that worried me......most was that the pinions gears had a lil bit of play when u hold them and shake them..... I heard its normal but when compared it to my OS 12 tr on the fw.. it was not that much and there was more play on the sirio......... is this normal the setup was done as the book........ do we need to add more shims incase of the 12 tup ???

anyone faced this problem........

Break in ......

the site says to do almost 10 tanks...i am on the 7th tank........right now can i lean it to the top range and richen it just a lil bit so that it would help me set the sleeve......or should this be done after the 10th tank. the website videos does not elaborate......

currently i am running really rich......but while running i have to give bursts as the car sometimes comes to a stop ..... so i have to go full throtle to get the car moving...... coz its that rich !!!

any suggestions here will save an engine !

cheers
