There's no point in asking for advice if you're not going to act on it. I should know. After 7 or 8 attempts to start the engine, it failed to start. Out it went (it really wasn't as difficult or time consuming as I thought). Then I made a 90 mile round trip to exchange the old new engine for a brand new engine. Tomorrow I'll install it on the bike frame and let her run. I was surprised to find the bolts to the riser plate and frame loose when I had made a full fledged effort to tighten them prior to installing the Predator engine. We'll try again, this time with lock tight or something similar. It was taking too much of my time but I'm convinced the problem was something I did. I did check the gas line from the tank and manifold as well. Both were tight and functioning properly. I'd like to do the Stage 1 kit install as well but I failed to order the vent caps and I can't find them locally. I don't like ordering online... Thanx again to SAS289 and of course Lizardking ...
