Hi captinjohn & ktan 73,
I don't have a video but I'll try and post one this weekend.
The carb came from Dave's Discount Motors in the USA, it's the same configuration as the original but has a slightly large bore and 2 mixture needles, it is a rotary valve type, Walbro WYK-194.
The priming bulb is great, just keep pressing it until there are no bubbles in the return line, plug the bell mouth and flick until it fires, one more flick and it just starts and idles.
I made all the brackets and adapters for the prop hub and RcExl ignition.
It's performance is very deceptive, it never sounds like is straining and with the 20 x 8 master will climb out at 45deg, the aircraft has 104" span and weighs about 10Kg.
Don't ever let anyone tell you that these are quiet with an open pipe, with the compression raised and ports cleaned up this thing has a very loud crackle to the exhaust and does not perform as well as it does with the muffler.
