i have a performance question. i'm a gearhead with cars and trucks, new to outboards. i cannot see how my carb on my 25hp tiller gets a lot of air under the cover... so would it do me any good to put a hole and maybe intake tube into my carb for a 'ram air' effect? with some sort of filter to keep out particles. would i get a noticeable difference? also, from factory my WOT on the handle is not near WOT on the carb, so i adjusted the stopper on the linkage to make sure that WOT on the handle opens up my carb all the way, is this safe and ok?
<br /><br />The speed marked on the tiller handle is a close approximation, but none are particularly accurate. The carb butterfly should be fully open when the timing is fully advanced. Sounds like that's what you did.
