Thread: Oil on intake; hard to start, backfire....

Tweet

I checked the very front ones and they were tight. But I couldn't check the next ones back. They are hex head bolts, and I can't put a tool on them w/the blower on.

I was thinking if they were loose or not sealed well, I'd have water leak up through them.

I do think I probably need to pull the manifold and put new gaskets down, but I'm just seeking thoughts before I tackle it. I'm guessing the backfire is because of the slow starting, it's loading up gas in the exhausts, and when it starts it backfires.
