My experimental biplane had been chosen to participate in a photo shoot for an aviation publication. The aircraft had to leave ZZZ field to meet with the photo plane at a different airport. After spending much longer than usual on the ground (approximately 25 mins) I was directed by ground personnel using hand signals to one of the active runways. I was then cleared by radio for immediate takeoff and told to expedite because of arriving traffic. As I taxied to take off, I saw an aircraft on about a 1/4 mi final, so I immediately started my takeoff roll. The engine came up to full power for about 2 seconds then lost power, then came back to full power only to lose power again. At this point I aborted my takeoff and told the tower I was having engine problems and needed to abort. Because of the arriving traffic, I started a left turn so that I would be out of the way of the aircraft on final. I was concerned that the arriving aircraft would not be able to stop in time, or not see me at all. I was going a little too fast to s-turn so I could not see the runway marker off the side of the runway. I was going about a fast walking speed when I hit the marker damaging my plane. I feel my mistake was being too concerned with all the active traffic as this was the first day of the week-long event at ZZZ trying not to tie up traffic by being in the middle of the runway with my engine problem. I should have stayed on the runway until I came to a taxiway or waited until slow enough to s-turn so I could see directly in front of my plane, then exit. I also learned my engine is prone to vapor lock with periods of high idle power in high temperature conditions.

Title: EXPERIMENTAL BIPLANE PLT ABORTS HIS TKOF AND DEPARTS THE RWY HITTING A RWY MARKER AT ZZZ.
Narrative: MY EXPERIMENTAL BIPLANE HAD BEEN CHOSEN TO PARTICIPATE IN A PHOTO SHOOT FOR AN AVIATION PUB. THE ACFT HAD TO LEAVE ZZZ FIELD TO MEET WITH THE PHOTO PLANE AT A DIFFERENT ARPT. AFTER SPENDING MUCH LONGER THAN USUAL ON THE GND (APPROX 25 MINS) I WAS DIRECTED BY GND PERSONNEL USING HAND SIGNALS TO ONE OF THE ACTIVE RWYS. I WAS THEN CLRED BY RADIO FOR IMMEDIATE TKOF AND TOLD TO EXPEDITE BECAUSE OF ARRIVING TFC. AS I TAXIED TO TAKE OFF, I SAW AN ACFT ON ABOUT A 1/4 MI FINAL, SO I IMMEDIATELY STARTED MY TKOF ROLL. THE ENG CAME UP TO FULL PWR FOR ABOUT 2 SECONDS THEN LOST PWR, THEN CAME BACK TO FULL PWR ONLY TO LOSE PWR AGAIN. AT THIS POINT I ABORTED MY TKOF AND TOLD THE TWR I WAS HAVING ENG PROBS AND NEEDED TO ABORT. BECAUSE OF THE ARRIVING TFC, I STARTED A L TURN SO THAT I WOULD BE OUT OF THE WAY OF THE ACFT ON FINAL. I WAS CONCERNED THAT THE ARRIVING ACFT WOULD NOT BE ABLE TO STOP IN TIME, OR NOT SEE ME AT ALL. I WAS GOING A LITTLE TOO FAST TO S-TURN SO I COULD NOT SEE THE RWY MARKER OFF THE SIDE OF THE RWY. I WAS GOING ABOUT A FAST WALKING SPD WHEN I HIT THE MARKER DAMAGING MY PLANE. I FEEL MY MISTAKE WAS BEING TOO CONCERNED WITH ALL THE ACTIVE TFC AS THIS WAS THE FIRST DAY OF THE WK-LONG EVENT AT ZZZ TRYING NOT TO TIE UP TFC BY BEING IN THE MIDDLE OF THE RWY WITH MY ENG PROB. I SHOULD HAVE STAYED ON THE RWY UNTIL I CAME TO A TXWY OR WAITED UNTIL SLOW ENOUGH TO S-TURN SO I COULD SEE DIRECTLY IN FRONT OF MY PLANE, THEN EXIT. I ALSO LEARNED MY ENG IS PRONE TO VAPOR LOCK WITH PERIODS OF HIGH IDLE PWR IN HIGH TEMP CONDITIONS.
