    4781- Not sure if after the dash is a B or an 8. underneath that is 2832 and on the top of the carb there was a GR5533B.

    Is that what you were looking for?

    I replied..

    Yeah i think its from a BB Olds and thats what my dad had so he just put it on there. I have been having some issues with the engine running right and maybe that is why..

    I find the boat real easy to start when she is cold but once she is warmed up she likes to stall and does not like to start back up until she has had some time to cool down..

    If tuned properly will this carb work in a SBC? Or am i just beating a dead horse.. I dont want to get rid of it so i might just buy something else and keep this until i find a BB.

    Thoughts?

    Dang. What do your plugs and transom look like. My machinest was tryin to tell me that carb choice isn't as critical to engine size as most people think, because a carb is supose to mix "x" amount of fuel, with how ever much or little air is going through it. Obviously to a point, I dunno, thats part of the reason I wanted to know what his plugs looked like.

    I'm waiting for the exhaust to cool so i can pull the plugs. transom looks clean, why do you ask?


    However i did just redo the floats and they where set all the way up so i turned them down per OEM spec.

    Well i pulled all the plugs. they all looked fine except one. all of the cylinders except 6 where slightly grey. No flakeness or gunk. However cylinder 6 plug snapped when i pulled it out and looked all black and nasty. Pic below.




    Could that plug have been bad and just fouled. Could only one cylinder foul and not the others?

    Delemorte, Sure would like to see the rest. Espessially number three hole, but all would be good. And agreed on the "alot of carb for a small block ". Unless it's a big small block. M

    Ask and you shall receive. here is number 3 cylinder. And all the other cylinders look just like this.



    BTW these plugs have about 10 hours on them. Probably less but 10 is a nice round number.
