engine probs???
I have a NEW o.s. max la .25 motor on my air boat i have troubles starting it it seems i have to prime it by putting a couple drops of gas in the card sometimes it fire right up and runs great other times it wants to start but only runs for about4 or 5 seconds and after about 5 mins of trying to start the darn thing it fires up. It runs fine when i get it started, the only prob i have is getting it started!!!!!

RE: engine probs???
Hey Jeremy,
It sounds like the fuel is not being drawn into the carb on the times it doesn't stay running. You want to take a look at where the fuel tank is placed. Is it below the engine or far away? I know there is a way to prime the engine without putting a few drops of fuel down the carb. I'm sure someone will post exactly how to do it. I think it's done by placing your finger over the carb and turning until the fuel comes up to it, then turn it a couple of more times, and it should be primed. Don't quote me on this....but I belive it's how it's done!!

Do one or two things hold your remote in the kill position as you spin the motor, or hold your finger over the exhaust(thats if you have a pressure line on it)

If I need to prime mine, I cover the carb opening with the tip of a finger, and TURN the prop over, NOT flip it over.
The ways Hal stated also work well. The benefit of putting your finger over the muffler outlet is that you can spin the engine over withan electric starter, glow igniter connected and when it fires up, you are good to go. With this technique, there is little chance of flooding the engine, unlike the other two ways.
