Weber Linkage Interference with Throttle Body

[DRTY_S30]

Hey guys,

I bought a new and never used Z Store Weber set up on craigslist and upon checking valve position for WOT, I found interference with the bolt for the throttle linkage and the throttle body.  Please see attached picture.  This interference is not allowing the throttle to open fully.  It is happening on all three linkage arms/throttle bodies.

Any suggestions?  I assume these are the nuts and bolts that came with the Z store kit but have no way of knowing because I bought it already assembled on craigslist.

Should I change the bolt for a skinnier one?  It is pretty small already.

Thanks in advance.

Try a panhead or panwasher style bolts
