Yak18t engine starting advice
Hi Guys, recently I purchased a Yak18T, a beautiful machine. I would like some advice on starting the engine. Im getting better at it but would like some advice from other Yak18T owners to see if Im holding my tongue in the correct position. At present I prime the line up to pressure, this takes about 8 pumps before correct line pressure. Then prime the cylinders 4 pumps, swing the prop several times and another 4 primes. On pushing the starter, it does fire normally very quickly, I then switch on the Mags. I have the throttle at about 1cm. Ive noticed if it doesnt fire within a few seconds, its not going to fire at all and best to wait 5-10 minutes before restarting. Its about 12 degrees here in NZ at present so not the best time to purchase a radial engine. Im paranoid about hydraulic lock by over priming with fuel (before starting I swing prop 20-30 times with lower cylinder valve open to drain oil). Any advice would be much appreciated
