Hi Corbin By any chance did this issue start after you replaced the fuel cap? I had a very similar experience with my Q2. Do you know if your ram air plumbing bends downward into the overflow tube

Does your intake path have SCAT tubing? I had a clever avionics tech remove the steel wire from the SCAT tubing that connected the air filter to the fuel-flow controller. Runup was fine, but on

In 35 years I've had two facet pumps fail. One stopped keeping up with fuel needs at high altitude. The squeeze bulb got me home. My method of fuel control is to run the pump untill I see header

Jay------------  Yuup---  I followed the plans when doing the install. the only deviation is the fuel filler on the side f the fuselage.   Although my fuel pump is switched, I will leave it on all

Very helpful information and greatly appreciated. I will be back out there in the next day or two. Thanks again. -- Corbin N121CG

That video pretty much rules out a throttle plate issue, MAP looks as expected with throttle travel. The engine sounds like it’s running fairly well other some hesitation on acceleration at low rpm.

Thanks, Shaun. I have the Airflow Performance injection system. I don't believe the throttle plate is loose but will add that to my list to check. The only MAP reading I have handy is the

Not sure what injection system you have or how your induction is set up, but is it possible that your throttle plate has become loose or unclocked? Not making full rpm at full throttle travel is

Thanks guys. I will double-check the manifold pressure lines. The ignition install had us "T" off the line for the Plasma boxes so it is possible something came loose. Corbin -- Corbin N121CG

I think I used something more like this as the thread form seemed to match up. It is a vented cap that I plugged and worked fine.

Are your manifold pressure lines correctly installed? Jim Sent from Outer Space

Hi Chris, What you have done is what the original plans call for, so should be good. Cheers, Jay

Hi Corbin, Is there a chance that your manifold pressure gauge is starting to crater and this is is influencing both spark advance and fuel injection? Just an uneducated question from a poorly

Here is what I did. The filler is in the side of the fuselage ,just below the Naca. Goes directly into the main tank and is hidden by the side consol.  The header is vented by a tube that goes

Me again. Haven't flown in months due to the Lightspeed ignition install, weather, you name it. Departed my home airport today and flew over to my new hangar. Upon takeoff, RPM at full throttle was

The low pressure on cowl is solely due to the sharp corner they have on the cowl. The air is forced perpendicular to the flight direction, then has to correct back rapidly and makes a low pressure

Thanks Sam, that's an awful lot like my setup except mine is flush fit to the fuselage. I cant believe how much knowledge is in this group and the willingness to share it. Thanks guys!

I used one of these: https://www.aircraftspruce.com/catalog/appages/bayonetfuelcaps.php I floxed the receiver to a PVC pipe. I've never had a problem with it, but both the gasket and the fuel cap

That's a way cool visual that has confirmed a suspicion I had about where the original builder placed the NACA ducts for cabin air.......about the center side of the canopy opening just below the

Here is the way I did it. Credit goes to Jim Doyle http://samhoskins.blogspot.com/2018/12/q-2-q-200-fuel-filler-cap.html?m=1
