After uneventful flight to IPT and landing then form IPT to SEG and landing; all on left tank (started with approx. 25 gals L & R tanks; changed to Right Tank before takeoff from SEG.  On climbout at approx 900 AGL; engine stopped.  I immediately lowered the nose and turned back toward the SEG airport to enter downwind for Runway 17; if able.  At the same time I also switched tanks back to the left tank; checked to see if the electric fuel pump was on (it was) and applied carburetor heat and the engine immediately came alive.  I kept a closed approach to Runway 17 (no other traffic); and announced my downwind; base; and final leg as as I normally have in the past and landed uneventfully.  I then did a run-up with both tanks and had no problems.  I then shut down and observed the engine for anything unusual.  Everything appeared to be fine.  I called my Mechanic and we discussed the entire event and he said there may be a problem with the right tank and to fly the airplane back to ZZZ (15 mi) on the left tank (which had plenty of fuel).  After successful run-up; and checking that the left tank was selected; I took off and completed the flight with no problems.  My Mechanic met me and again questioned me; and as of this writing is troubleshooting; what appeared to be temporary fuel starvation involving the right tank; which had plenty of fuel.
Musketeer pilot reports switching to the full fuel tank prior to takeoff then having the engine quit at 900 feet AGL.  The fuel selector is placed back to the left tank and carburetor heat is applied.  The engine immediately catches and a precautionary landing ensues.
