check all the eletrical. are the spark plugs getting spark. just a thought but pour some racing gas in the carb to see if it starts. have some water near by though.
just tune the thing up and make sure the engine is getting fuel and spark. i would say check compression but i have no idea how to do that on a rotary engine

verify it gets fuel and fire, then it is highly likely its flooded out. the rotaries are super notorius for flooding, even the brand new injected ones flood. remove spark plugs ( all 4 are on drivers side mid way down on block) clean and dry plugs, remove fuel source to carb or at least hold accel to floor. crank engine for 10-30 secs. then squirt a ounce or so oil in each rotor through plug holes. install plugs, pour a couple ounces down carb and re-apply fuel source. start cranking engine over, and you will probably need to keep foot to floor and it will eventually build compression and begin to fire. oh and be prepared for smoke. and its best to replace spark plugs and buy a spare set and put in glove box. and if flooded may want to check oil for fuel saturation.

I know it is getting good clean fuel now (smell) and she tries to fire, but just can't seem to do it. I pulled the spark plugs and Mikey scrubbed them good with a wire brush the size of a toothbrush. The plugs on top had oil on them, but not the ones on the bottom.
Are you saying to dump some oil in the carb. too?
Thanks for the help, I gotta get this thing running.

just a litlle bit of oil, down carb, maybe a good way is to use a jar with a vac hose in jar and hooked to manifold vac. let the engine draw a 1-2 ounces through the hose. you need to probably hold accel wide open to help with possible de-flood condition. they can take a while to finally bust off. just dont burn starter up. its good to put a boost charger on battery for a faster spin. let starter cool. sometimes it take a quite a few crankings and it will finally start then ease off throttle and feather it for a min or two untill it quits smoking. somepeople try using a little ether but thats dangerous

I forgot all about this thread.
I put new plugs in and finally got it running a couple of weeks ago. You guys wouldn't believe the smoke that came out of that thing. I drove it around for a couple of hours and it ran fine, no overheating or anything.
But now, I have a different problem. A few days after running it, I went to run to the store in it, and after starting it, the add coolant alarm went off. I shut it off and popped the hood and had coolant spraying out of the vent cap on the overflow bottle.
What appears to be happening is that the radiator is building up pressure really quick as if it isn't getting into the engine. I thought maybe the water pump just quit. Any ideas?
