Good Morning, Where can I find a copy of the installation manual. The website returned zero docs. Thanks.

Scott Perdue did a review after six years of ownership. He's tried lots of different tugs and I find his reviews credible. I think it would be easier and safer for my hangar. I have multiple AC in my hangar and it would be nice to be able to check clearances without being tied to the front of the aircraft.

8K, 29/2400 or 30.5/2250, 172-174 TAS.

Yes, the KAS297. I also enter the desired altitude into the GI275 as it offer altitude call outs, alerts, TOD, BOD and what I call the banana on the map to show my both. My navigator is a GTN750. Works great but definitely no Alt. Select or ROC via the GI275.

I have a Pair of GI275s with a King KFC 150. Works well! My alt preselect functions are not available on the 275 but everything else works great. I’m not familiar with the KAP but the KFC has a flight director and it works well with the GI275s. No regrets.

I’ve flown about 5 hours since my last post. First crank the #1 jug lagged less than 5 seconds. I surmise the lifters had to pump back up. Next two, #1 came online in perfect sync. Ran for awhile LOP and performed an inflight mag check with satisfactory results. I have a flight Monday morning so I’m going to repeat and upload all the data to my Savy ticket. Feeling much better but still scratching my head. Thanks again.

I agree with the reamer suggestion as a matter of good practice and I may come back to it later. I could not give them a quick check because I don't have the correct size reamer. Mcfarland is out of stock of the guided reamers so I chose to put her back together. I'll have the correct reamer in a couple of weeks and after feeling the guides I'm confident they won't stick open or closed in the interim. Tried plug swapping. I did bench test all the plugs (fine wire) under pressure but I did not check resistance. Good suggestion, thanks! I'll be doing an inflight ignition test this afternoon.

I did, see my previous post.

Starting to feel like I'm hunting Zebras with regards to the valves. Both intake and exhaust are smooth with the appropriate wobble. I had another A&P take a look and I did not offer an opinion prior to his diagnosis. He concurred all is well. I also uploaded a video and pics for Savy to diagnose. Same. I bought these jugs new from Lycoming and sent them directly to Victor for valve work. I'm reluctant to ream just for the sake of reaming as I'm in the do no harm camp. I may come back to the valves but for now I'm starting to re-diagnose. Thanks again for weighing in!

Yes, but thanks for the advice.

Well, no joy. Pulled the valve springs and the valve stem is smooth as silk in the guide.

Thanks, I had read this. I'm ordering but preparing for plan B.

Thanks!

Thanks for the responses. I use 20/50 with camguard. Oil consumption is minimal. I believe reaming the guide is the solution but it's great to hear a consensus. I'm a Savy user and they offered the same response. To bad I don't have the appropriate size reamer in my box. Mcfarland is out of stock. I plan to back order and clean the valve stem up to buy myself some time. I don't want to waste time doing the job twice but without the reamer I don't see I have an option. They estimate 15 June but since COVID I've much more skeptical. Thanks again.

Good afternoon, I've been working an issue with my Bravo and as always, I'm reaching out to the group for advice. M20M TIO540AF1B 300 hours SMOH (Victor Aviation) On 4/18 I experience a rough running engine after start up. After 30-45 seconds it cleared up. The remainder of the flight was ops normal. Next two flights were normal as well. As my annual is coming due I performed a 100 hour on the engine. This included plug cleaning, testing, and rotating-timing check-and borescope. Post maintenance I started the engine to check for leaks and experienced the same roughness for roughly twice as long. My Son observed rhythmic puffs of black smoke and the data shows #1 and #2 EGTs slow to rise. After the roughness cleared up the engine ran normally. #1 Valve
