I finally got my 2 running half way decent. It seems to be smoking a bit and it smells like fuel but I have never seen a car smoke this much from fuel without fouling the plugs. when its idling not really any smoke but when you rev it up it is belching it out pretty good. Give me a little insight here, this is my first rotary project and I am not sure what the possibilites are. I know if it were a V8 smoking like this carburation alone wouldnt smoke this much.

The engine is a 12a streetport with a mikuni phh 44 jets are 240 main, 200 main, 70 pump, 57.5 idle jets.

 

what color is the smoke

 

whiteish for the most part really smells BAD ! smells very rich. I am thinking its some oil seal or something. I can change the jets and it doesnt help much if at all.

I should take a picture, but you guts would brobably laugh.

 

here is a picture, the car is cold now and when its warmed up its much thicker

 

White smoke is almost always coolant leaking! engine oil burns a blueish color, and too rich usually burns black or dark brown. There are always exceptions. Rotaries are very easy to work on, especially when trying to diagnose a leak. If you blew a coolant seal it would burn blueish smoke, no question. If you blew a coolant seal the car would burn white smoke, smell of coolant, and become hard to start, especially when cold( are u losing coolant?). Your car could burn any kind of smoke and still smell like fuel if its running rich. Most rotaries fumes smell like gas due to the high amount of HC's that get by. Hope this helps.

 

changing jets won't have much affect at idle since the idle circuit is seperate from the primary circuit. Have you turned the top mixture **** in quite a ways to lean it out? Do you know if the thermal reactor is getting air? there are tons of things to test - do you have a vacuum gauge hooked up to the engine to tune with?
