Greetings,

I have a DA-50 mounted in a BMW Yak that I purchased from a fellow pilot at my field. So far I have 8 flights on it but the previous owner flew it for several months before upgrading to 100cc planes. My question concerns starting the plane for the first time of the day. When I first flew the plane it would take 5-6 flips, with choke on, before it 'popped' and then I would shut off the choke and flip the prop once again and it would start right up. Recently, during the unusually hot weather here, it wouldn't start at all; kind of acted like it was flooded. So, I would let it sit for 15-20 minutes and then try cranking it over again with both the choke on and off but nothing happens. Each time I have had to use a high-torque starter to get it to finally turn over. Once it did this, it ran fine the rest of the day; it just seems to act like this on the first start of the day.
Is there anything that I should look at or adjust to correct this problem? Please let me know.

Thanks,

Mark
