Super Tigre question
I've got a Super tigre G34 in my Sig Kobra which replaced an O.S. 25 LA. Two questions:
1. I've heard to ditch the stock glow plug that came with the engine and replace it. Any suggestions as to with what?
2. The Kobra is a small plane so the Super Tigre muffler slides a good distance on to the exhaust header. Most of the header is protruding into the muffler. I was wondering that with all that header tube inside the muffler if there wasn't a bit of a back pressure situation being created at full throttle. Is it worth it to trim the header tube back a bit or leave it as it is?
Thanks,
Dan
