SureFly Hot Starts

[Marauder]

Just had a SureFly installed. I’ve read numerous accounts that hot starts are easier. I’m having issues with hot starts.

 

For those of you who have installed one on a IO-360, did you need to change your hot start procedure?

 

I’ve used the same hot starting procedure since I bought the plane in 1991. On shutdown, leave the throttle at 1,000 RPM. On hot start up, leave mixture out, crank and when it catches (3 or 4 blades), advance the mixture. This doesn’t work any longer. The only way I could get it to start was to use the flooded start procedure.

 

Am I looking at a SureFly issue or something else?

I have exactly your setup.  I didn’t change hot start technique at all with the SF.  It fires maybe one or two blades earlier but otherwise it’s the same as before.  If you “miss” a hot start, you might still have to go to the flooded procedure.  That only happens to me about once a year or so.  Your previous technique is exactly what I use/used.

And you didn’t say, but the SF is on the left, correct?

Honestly, i haven't noticed  a change in the hot start procedure, it might start a blade or two sooner ,shrug.

flooded procedure seems to work better however

Thanks for the reply. I suspect something is wrong with either the mag or something else. I’ve tried a different hot start that another IO-360 uses and it isn’t any better.

I recently talked with J owner who said that she had a SureFly with variable timing installed. She said that her CHTs were 25-30 degrees higher on climb with the SureFly, then with the mags. She said that she had the SureFly SIM reset to fixed timing and the problem went away. I asked her what power setting she used on climb and she said usually around 26 squared. 

I didn't think that the variable timing kicked in unless the MP was less than 25 inches.

Has anyone else experienced this?

And good to hear from you Chris. I was beginning to wonder if you were still around. I haven't really spoken to Jack since he sold his C.
