decel to idle

Postby amytom » Wed May 15, 2013 9:23 am

My port engine has been having an issue for quite some time. It idles okay when you start it up, runs fine at speed but when I decelerate it dies instead of ideling. For other reasons the fuel pump and carb have both been changed; the fuel pump with a new one the carb I rebuilt. Compression, timing, and cooling are all good.

Any thoughts?

Have you tried adjusting the idle screw a bit to increase the idle speed? It's possible that in all the mechanical work the cable is slightly off from the original position.

Eric,

Thanks for the suggestion. Yes bumping the idle up was one of the first things I tried but taking it too high causes issues with shifting in and out of gear.

The amount I was able to bump it up didnt do the trick.

Did you figure this out, Tom? We have similar issues. I have been assuming the carb is messed up in some way and needs a thorough cleaning.

Not yet Mike. Unfortunately life keeps getting in the way.
I plan to take alook at the intake manifold gaskets and will probably swap the two carbs to see if the problem moves.

I would love to swap the carbs but I find removing the port one to be bad enough. Getting at the starboard one, the carb that is working, looks impossible. I did try that with the fuel pump though.
