Dear Listers, There are just a couple days left for this year's List Fund Raiser. If you've been putting off making a Contribution until the last minute, well, this is it! The last minute, that is... :-) There are some GREAT new gift selections to choose from this year. I personally want at least four of them! There's probably something you can't live without too! And, best of all it supports your Lists! Please remember that there isn't any sort of commercial advertising on the Lists and the *only* means of keeping these Lists running is through your Contributions during this Fund Raiser. Let's make this a "Black Friday" for the Lists! Please make a Contribution today! http://www.matronics.com/contribution Or, drop a personal check in the mail to: Matt Dralle / Matronics 581 Jeannie Way Livermore CA 94550 Thank you!

The second start was worse than the first. Excellent air pressure on both, I did not check the bat voltage during start. The prop barely turned after depressing the start button. I could not hear any air leaking and the prop did not hang up in any one spot (ie broken air line to cyl). Just turned painfully slow. Both times I pulled the prop through numerous time as I always do prior to start. Any thought on this one gents?

If your model has the manual lever on the side to open it, I would suggest trying it out and see if the prop spins normally. I am not suggesting you start it this way except when there is no other choice, but if you use the manual valve lever and it spins normally, then you can pretty much feel safe that you have figured out what is wrong. You also brought up a very good point about battery voltage. Just for the record, I have run into a lot of battery issues over the years with both ALL of these aircraft. Since the battery is not used to crank a starter, and really requires very little energy during start, people tend to ignore and never test the batteries. A crude but effective test is just to hook a 24 volt landing light up to your batteries while you also have a voltmeter connected to them. If the battery voltage drops to below 20 volts, they are SHOT. Flying with batteries in this condition is also a good way to cause damage to avionics. And yes, very low battery voltage during start will cause the starter valve not to open fully. So battery voltage would be the very first thing to check.

If you have the manual starter valve you should be able to hear the air leaking while the lever is depressed. Doug Sapp has these gaskets in stock.
