Wagstaff Extra 300
My 2 1/2" 8-32 bolts go into blind nuts in the firewall with lock nuts on the backside. That's all folks.
PS; If you buy standoffs from Roger you will not have a hardware problem because his standoffs are threaded on both sides. No need to locate unusual hardware. I wasted most of a day and half a tank of gas locating the long cap head bolts.
Did anybody see fancman's photo on previous page? Looks like he is using metal push rods for the throttle and choke. I was under the impression that you must use non conductive (plastic) push-rods to contain the RFI with gas engines. Am I correct or what?
