Quick start, quick stall.

My starboard engine will immediately start, run for a second or two and stall. It will do this about 3 times before it will keep running. Port engine went throught identical routine and starts and runs fine.

I recently did some carb work to solve a chronic running rich situation and this is probably a by product of that. I found float levels very high and lowered them, among other small settings and adjustments.

Any ideas before I just take it apart to look for something I don't now yet?

Thanks!

Oops...1990 OMC 5.7 litre with Holley 4175 carbs.

Ayuh,.... My 1st guess is, ya went to far,.....

 

[Gilded_Splinters]

Agreed. Unfortunately, this is one of the few Holley carbs without external float level adjustments.

Thanks.

Choke working properly?

 

[Gilded_Splinters]

It seems to be, yes.

Something odd did happen this weekend. I was doing some electrical work behind the dash and needed to turn the key to the on position to check something out. I was reaching from a strange position and turned it too far and it fired right up.

Ordinarily, I have to give the throttles a half pump and "get them running" if you know what I mean, but it started right up and idled very well with no throttle input at all. I was in total agreement about the float level, but this makes me think again.

What say you?
