Aerocarb with Optional Air Filter
I checked out the Sonerai this weekend and it turns out the airfilter was not the problem. Looks like it was a loose spark plug. I installed a new set prior to flying. One of the plugs was different from the other three and this was the one that was loose. I'm sure I checked the torque... -

Aerocarb with Optional Air Filter
Yes, I cut out the internal web and it ran much smoother. I also used a dremel tool to smooth out the inside of the intake. Ken -

Chad, When running the engine on the ground the plugs were coffee colored. After the flight they were very black. The engine runs totally different in the air than it does on the ground. I'll post pictures soon. Ken -

Aerocarb with Optional Air Filter
I believe you're right about the air filter. I had a test pilot fly the plane with the aerocarb on the old engine using RAM air and it flew fine except for pressure baffle issues. The #4 main bearing burnt before I could fly so I bought a new GP engine. It should be ready to fly again in a... -

Aerocarb with Optional Air Filter
Ed, I tried the #2 needle and set the mixture for WOT. When doing so, it would run rich at idle. When using the #3 needle the mixture was right at all power settings. By the way, what type of air filter are you using? Ken -

Aerocarb with Optional Air Filter
I'll take pictures of my setup as soon as I can get back out to the hangar. Here is some additional info: the prop is Ed Sterba. Intakes are GP with the partition cut out as recommended by Chad. The carb is mounted horizontally beneath the engine. The air filter is mounted as recommended by... -

Aerocarb with Optional Air Filter
Anyone using an Aerocarb with the optional air filter on a GP 2180? I flew my Sonerai II LT for the first time today. Static rpm with a 53x43 prop is 3100. Engine runs very smooth on the ground. The problem is: after liftoff the engine runs rough and the plane will climb at only 150 fpm... -

Spinner Bulkhead
I think I'll take your advice and add the bulkhead before flying. I've had this plane for 3 1/2 yrs and haven't flown it yet. The builder was a machinist with more time than money and cut critical corners. I think I'm down to the last few issues, including a new engine from GP. I'm... -

Spinner Bulkhead
Hello I purchased a Sonerai II LT with 100 hrs. A friend said a forward spinner bulkhead is required. My plane does not have one. There are no cracks or problems with it. Is a forward bulkhead really needed? Thanks Ken -

static rpm
I had a similar problem with my engine. I have a 2180 VW. I tried diagnosing it for 3 years before finally pulling the engine and shipping it to GP. The problem was the prop hub and bearing assembly. The builder was a machinist and made the parts. He forgot to drill one of the holes to...
