What Header are you using?

aloha Rene I am running the novarossi header

 

[Rene Danner]

Oh OKay, I had a Tecnopower header and the little nipple on he bottom had to be plugged. I also noticed that the motor loves fuel on my flow meter I am at 120. I have not tried a 442 yet you may want to try a little smaller prop.

Rene are u running the stock carb or a modified I swapped out the stock plastic arm with a cmb aluminum arm but can't get it tune right so I swapped to a novarossi mod carb from woods with remote needle flowed with Boris meter at 160

Sorry to say this but the OPS carb has not worked at all,I am using a F Orlic carb with a 338 bore.I am also using a boris meter gen 3 and 160 seems to be a good starting point for most 21's not the OPS bring it to 120 and try again also let it idle a bit before putting it in the water to let it build a little heat.
