Looks awesome!!! How much did your Yokes cost? I am really debating sending mine out at annual this fall.

I will be there! Tyler

What exactly do you mean by morning sickness? After more investigating my mechanic could not find anything unusual. All the spark plugs are in good condition and compressions were 79, 78, 79,76. He shined a light into the cylinders and said he couldn't see anything unusual. We checked for fuel leaks and there was no blue staining anywhere. Before I got the plane, the previous owner only put 80hrs on it over about 6 years. He tried to fly once a month. Now that I am flying a lot more is this common? My mechanic said it may fix itself after being ran some more. I did not have a chance to fly last night and get a video but I should be able to in the next couple days. I'm sure it isn't anything major I just get very particular when it comes to the engine and figured I would pick your guy's brains. I appreciate all the help!

Yep! They are 100hr slick mags. RPM drop is about 75 on both mags at 1700rpm. They are tempest plugs. When we take them out to check compression I'll snap some photos. Annual is due in November so if they're looking old and have a bad gap I might buy a new set now. We had the cowling off recently and I remember taking a good look at the fuel sender and injectors and did not see any staining. I'll pull the bottom cowling off as well and have my A&P take a look at each cylinders intake manifold. He flew the plane with me last week and was thinking an exhaust vulvae may need to be bored, but he wanted to look at a few other things first. Thanks for the help everyone, I'll have more updates this evening.

I am meeting with my mechanic tonight and will have some for info for you guys. My #1 EGT runs cooler than the rest but by no more than like 80 degrees. I have not noticed the issue when landing just when taxiing around bellow 1100rpm or so. I do not think it is a fuel leak because i have not noticed any blue staining from the cowling but will do some more investigating with the cowling off. We are probably going to start with compression and when we run it up I will get some video to share. Thanks for the help!

100hrs since new mags, 100hrs since IRAN, 600hrs since new engine. It's not even that the engine is running rough...its more of a small vibration/misfire. I have flown rentals that run way way more rough haha. I might go take a video tomorrow. I do have a JPI 700 and there is nothing unusual with the EGT's. I might go do a run up this evening and play with the mixture again and just double check she isnt idling too rich

Yes we tried leaning and it did not help. And yes! It has every speed mod you can put on it. It was an old Mod Works bird. Love it!

Hey everyone. I own a M20F that I just recently purchased. The only thing I have found with the airplane the bothers me is a slight misfire at low rpm settings. The mag check is really good and all the EGT's are very similar up at cruise. I have tried running the engine hot on the ground to burn off any carbon deposits on the spark plugs but the plugs seem to be fine. Anything about 1300rpm or so there is no misfire at all. The engine run perfectly. The engine is the IO-360-A1A. Does anybody have any ideas on where to start? Thanks
