Under these conditions, a vapour lock is quite possible. Normally if the circulation in the fuel lines is OK, then it's not so much of a problem but perhaps the Ventus does not have a return line? This is what DG say: Approx. 1⁄4 hour after retraction of the hot engine vapour bubbles may start forming in the carburettor which makes engine start difficult. In most cases the engine will start but refuse to accept throttle and may stop again. To avoid the engine stopping press the starter button again, if necessary several times. Each time you press the starter button the primer valve opens and injects some additional fuel to keep the engine running. Does the Ventus Solo have a fuel injector? The normal way to check for things like this is to remove a spark plug, rest it on the side of the engine and crank it over, watching for a spark. You can't hand turn the prop because there's normally not enough revs for a spark so you have to use the starter motor. Don't do this on a glider though! It is really dangerous for a few reasons. The motor may start but also the fuel vapour may ignite and start a good fire. I've got away with this with car engines but a friend torched his mates Alpha Spider and it burned to a write off. The newsgroups are really your best bet where you can get a range of views… a lot of them barking mad but that's what you sign on for isn't it?
