Ok, I have an honest good ole question. I have a 3W120 on a 35% extra 260, 28-10 prop. I am having a hard time starting it up. at first I thought it was flooding out but when I pulled the plugs out they were dry. This is after gas is running out of the carb. I put the plugs back in and try again. Same thing, no fire and gas running out of the carb. I walk away and let it sit for a few minute go back and flip it 2-3 times and whammy it hits . I then take the choke off and it starts right up.

I think what might be happening is the carb block has some pin holes in it and will not start till it gets enogh fuel in it to satureate the carb blkock.

Anybody else want to take a swing at it.

After it starts up the first time on the day of flying it will start right up the rest of the day.
