"If the end of the intake that goes into the carb has a rounded edge where it should meet the o ring , it's likely your problem .
Best to flatten that end for a better seal against the o ring"
Here's what it looks like:
it is slightly rounded. this might be it. if this is indeed the problem how would you recommend flattening it.. grinding it? sanding it? replacing it?
"Did you change the intake to a aftermarket 15mm intake?"
It is the correct intake. 15mm. worked with other bings of the same size.
"Anyhow I ended up using the yellow Teflon tape"
I've heard teflon tape and I've heard furnace tape. Can anyone speak to which is better? or maybe a better question is how permanent and reliable of a fix is this? I want to leave the days of air leaks behind me with this ped. (edited)
