testing in barrel

[newboater1012]

I am testing a 1959 johnson seahorse using a half-barrel. There is a lot of smoke. I read in an answer somewhere in the forum that when testing this way there will be smoke - but I can't find the link again. Can someone out there answer this for me?

The smoke will come straight up out of the barrel, and be sucked under the hood, and into the carb giving erratic running. If you have one, blow a fan over the barrel when the engine is running. This work's well for me.

With mine in a barrell, it smoked to the point that I was embarrassed. Then I tried it out on the lake and the smoke was nearly non existant.

yes exactly, and testing in a barrel is just that testing, don't get caught up in tying to tune because before long your carboned up and plugs are beginning to foul up.

Re: testing in barrel

thanks I will try this. I was afraid all the smoke indicated something was wrong with the engine.

If you can foul up an engine running in a barrel, don't leave the dock with it.

True, some engines can run all day in a barrel if you feed in some cool water, my 43yr. old evenrude won't, it will begin to foul plugs even on the lake if I tool around too long.

If the engine is correct, it should'nt foul plugs'. My 57, 18hp does'nt, neither does the 55 7.5hp.
