I was hand propping (without plugs) to get oil pressure on my newly rebuilt engine. The impulse coupler on the left mag was doing it's clicking and felt normal. There was a definite click but didn't take a lot of resistance to overcome. After I got a slight oil pressure I went back and turned the prop some more. After quite a few blades the area where the click is got insanely tight! I could still get it to turn but it hit a hard stop at the normal impulse coupler snap spot. I stopped and came here in hopes that someone will hopefully give me some advice on what to do.
Should I pull the left mag and see if there is something wrong with the impulse coupler or is this normal? It sure didn't feel normal. There was also what sounded like a creaking sound coming from the left mag after it got tight. It only makes the sound when it is winding up the spring in the mag and ready to release. The engine also spins smoothly backwards.
The engine was ran for almost 2.5 hours at Aerosport but they used a slave left mag.
Could really use your guys' help on this one, I'm getting very frustrated with the project at this point...
Thanks in advance everyone
