I'll move the prop, but same issue. If I put a battery charger on, the engine turns over easily. Main air pressure is high and constant both tries. Should I just replace the valve or are there possibly larger problems afoot.

By adding the charger, you temporarily solve the problem. A guess.

It is an electro/pneumatic valve, meaning it has a solenoid in it which opens the valve and allows the air to get to the engine. Your solenoid works better with more charge (on the charger) because it is corroded and requires more power (amps) to open the valve. However you might try flushing out the pneumatic side with WD-40, give me a call and I'll explain the process. I have them in stock if needed.

Dennis Savarese" Subject: Re: Yak-List: QDF-1 AIR START SOLENOID VALVE Byron is correct. The air start solenoid is not fully opening because of the weak battery OR there may be some gunk inside the solenoid that is causing it not to fully open. Replace the batteries first and try it. If it still acts up, I'm sure Doug has new air start solenoids in stock. Dennis A.

Look at the voltmeter when you are starting. If it is at 24v (it should be) and you have the problem , you are looking at either a bad start valve or bad connections to the start valve. If the voltage is below 24 volts then either your a Battery is bad or the battery is not charging properly. Make sure you have 28v when the generator comes on-line. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 brian@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message yak-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Yak-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/yak-list Browse Digests http://www.matronics.com/digest/yak-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
