Which grade gas for street port?
My 84 12a has a mild street port. I was wondering what grade gasoline I should use. It has a Holley red fuel pump and I only get about 12mpg. I've researched and a street port shouldn't affect mpg. So is it the pump? Sorry if these are obvious questions I'm new to rotaries. Thanks in advance.

The carbuerator is stock. I'm not sure if it's been modified to allow more flow. But most threads I've seen say they get around 17mpg even with a modified carb or port. So I'm a bit confused. I'm going to order a stock fuel pump and try that.

it's not likely to be the pump. with my Carter on a tired, stock 13B (with Dell'Orto and all 6 ports open all the time), i was getting 24 MPG. withe the same Carter on the streetport 12A (with Nikki) that followed it, i was getting roughly the same. my brother's car, with a streetport 13B and Holley pump would get roughly 20 MPG.
you should look to getting a fresh tuneup and then go from there.
out of curiosity, what exhaust system do you have and what plugs do you run?

I was getting bad mpg's and checked my plugs they had build up on them so I changed them and it made a HUGE difference. I was getting a lot of back firing on decel now it's a lot better. Wouldn't hurt to check them even if it was just tuned up. Unless u changed them u don't know for sure

I filled up my tank last night and I got 14 mpg this time. It is my first car and manual so I guess I just got better at controlling torque. However I will still check the plugs today and clean the carb sometime.
