1974 25 hp evinrude won't run unless choked???

[fishhawk]

I have a 1974 25 hp evinrude that won't stay running when you release the choke???????? HELP!!!

 

[crazymanme2]

Has it ever ran good :?:

May just need a good carb cleaning [-o<

Need a little motor history? :roll:

I would start with a carb cleaning. it sounds like the high speed jet is clogged.

Ditto. I had the same problem, and cleaning the card fixed it.

well, that was mt 1st carb. job, but it was a piece of cake, can't hardly go wrong. It's a 1976 25 hp. 'rude. Manual choke

I put a block on it that i bought off of ebay, starts up fine( w/choke on) untill you release the choke, then it just dies, starts right back up, but the same thing.

I have a 25hp Mercury that was doing the same thing, turned out to be the fuel tank not venting properly.

Hmmm, well I use the same gas tank and lines on my other motor and it works fine. So I doubt thats it. I'll pull the jet and see what happens. Thanx, any and all help and criticism are welcome.
