PIGDOG i agree with the stock studs and the slip on spacers (i have 8mm slip on spacers haha but there is still plenty of thread in the whel nuts) but the bolt on spacers cant be that bad with the stock studs can they?
sounds like my carby. my carby wont idle below 2000rpm, it runs really rich and sometimes when i turn the car off it starts back up for like 5 seconds haha (it does really good key bangers because it runs so rich haha)
