Took the plunge and ordered the compact canister Pitts style muffler from J-tec. While waiting, I decided it was time to set up the fuel line, choke, and throttle servo. I have drilled the firewall for all three, installed the throttle servo, and am working on the choke linkage. I will post the pics when completed. To avoid the interference from the fuel tank, I have moved it back from the firewall, and placed the servo and choke linkage just behind the firewall. The choke will be a manual lever using 1/2 of a servo horn and after installing it, I did have to increase the size of the hole in the firewall. No big deal, and it now looks like a keyhole. Will finish up the connections tomorrow or next day.
