No you wont need an ntire 1400 dollar rebuild kit. Most people perfer to use all new parts when rebuilding, but you can get away with out it in some areas... depending on the state of your current internal pieces. As far as ATF, a lil goes a long way!!!!!!! lol i remember the first time i did the ATF trick... Pop the front trailing plug... attach small piece of fuel line to squeeze bottle of ATF. Squeeze 1 squeeze (normal squeeze, dont get crazy) into spark plug hole. Reinstall plug. Start car. tell everyone in your neighborhood that your house isnt burning down, nothing exploded, there is no fire, and wear some sort of a mask, and possibly take a video... It will take a handful of minutes to clear out from all the smoke, and will smoke so bad that you'll think all hell is breaking lose. When all is said and done your flooding issue will be fixed (until it floods again) and it may very well loosen up stuck seals and so on... It may also do some damage to the internals... so be very gentle with the ATF, and put a 600 on that thing! Then take it to a rotary guy, like Samito, and have em look at it and get a better picture of whats wrong with the engine.

Thats not going to do anything so dont waste your time bro. You can try the ATF but usually its only when carbon is build up inside the seals. Give it a try you have nothing to lose...

bro the same thing was happening with my sammy with a 12a and when we took it apart the slots where the apex seals goes were to wide open for the seals....i mean it was the worst i have ever seen the housings were really bad and the thing would still start and i would drive it 12a's will run for ever thats why i love them more than a 13b even tho parts are getting a lil hard to get my guess is that they might of used new parts but the rotors were bad like out of spec to be able to be reused also if u used a regular compression tester like for a piston eng it will not give you acurate readings u have to use one specially made for rotarys also that carb is way to big for a street port i would go with a 600... if bridge ported then i would go with a 650....the carb needs to be worked on ( some parts repleced and some added ) you cant just slap a holly and hope it works...when i rebuilt my eng i did have to squirt a lil oil to get it started for the first cople of times ( like 5 or 6) wile the apex seals set with the housing but then it would start right up everytime after that also about the omp if the link is not hooked up then make sure that they didnt tie wrapped it down all the way open.....also this is the reason rotarys have a bad rep...people trying to rebuild their engines reusing bad parts if you have to re place the apex seals why not replace corner seals and springs specially if not using 93+ corner seals springs also replace the side seals and springs.....half way build eng can only give you so much if you have any questions let me know i have a really good mechanic in the pinellas park area let me know if this helped

check all the way down at the actual omp if its not hooked up you are not getting oil to your carb like you are supposed to i would pre mix the gas....1 oz of oil per gallon of gas my first mechanic always told me that 2 cycle racing oil works great but thats his opinion other might tell you other wise but u must premix if omp is not in use
