201er Posted December 26, 2011 Report Posted December 26, 2011 A mechanic suggested to me to use more throttle when starting and sure enough it fires up sooner with less cranking. Obviously this is easier on the starter but how is it on the engine if it fires into 1200-1800RPM right away based on the throttle position? I bring the throttle back first and then advance the mixture. So is there anything wrong with using more throttle to start with less cranking? Quote
201er Posted December 26, 2011 Author Report Posted December 26, 2011 Speaking of priming method, what I've been doing (mech's recommendation) is full throttle, full mixture, boost pump on, watch until maximum fuel flow is reached, wait 0-2 seconds depending on conditions at this fuel flow, then mixture idle, fuel pump off, throttle 1/4-1/2 way in, crank, bring throttle back, put mixture in. He said by priming with full throttle, it opens the fuel servo and gets better fuel flow for priming. This has worked very well for me but then again before I had a weak impulse coupling so it may have all been about that and not the priming method. Quote
Immelman Posted December 26, 2011 Report Posted December 26, 2011 Here's a little trick I learned a while ago that has helped starts immensely without having to advance the throttle past the 1000rpm position: After you prime (with the fuel pump), sit back and wait about 15 seconds -- longer in colder weather -- for the fuel to evaporate a bit. For me, this makes the difference between having the engine fire on the first blade vs cranking around 5-10 times. Try it, you may be surprised! Quote
jetdriven Posted December 26, 2011 Report Posted December 26, 2011 I just tried the wait 30 second method today and the engine fired om the second blade. Cold start. Quote
