Help! My power just cuts off under high load at about 3 to 4 k rpm. This just when I used to get the rush from the rotary power. Any ideas where to start looking? Tried fuel filter/plugs/airfilter/and airflow sensor seems to move normally. And also what does premixing TCW-3 do for the rotary engine/do you keep the normal oil system working if you pre mix?

Does it just cut off for a second, then kick back in? In cold weather?

sounds the secondary fuel injectors

Yeah, that's what I was thinking. Mine hesitates (more often in the cold weather), but doesn't completely cut out. Not sure how to fix it, but it's not a big enough deal to me.

all you need to do is pull out the secondary injectors and send them to rc engineering, but to do it right i'd pull all four, that way you wouldn't have to worry about the primaries starting to leak, plus you would regain the lost power.

Where is rc engineering located? And I haven't noticed a loss of power, just a slight hesitation at exactly 3800. Ok, how did this end up being my question? https://www.nopistons.com/forums/pub...#>/biggrin.png

Temp doesn't matter and it completly dies for several seconds. Any idea how difficult it is (expensive) to have the injectors reengineered or replaced? Is this a do it my self possibility? The injectors do some times leak after it is shut down causing the common flooding problem. If I rev it just before I shut it down this seems to help the flooding, but if I forget it will flood about 1 out of every 20 times.

ok, mine does the EXACT SAME THING....hesitates, but kicks right back in, instantly...because the power comes back instantly, I haven't worried much about it



some folks have told me to reground my ecu, but I don't know if that's for hesitation, or loss of power at certain rpm, with no return of power after that....anyone care to clarify?

Not sure about the ECU thing, but critter, send them off to be either fixed or replaced. That should fix it.

there is a ground on top of the engine that has to handle all of the current and if the ground is loose or corroded it will make the hesitation worse
