Hey guys - first post!

Been working on an 89 hurricane on and off for a year. I've worked out my fuel pump and pilot screw issues, now I just need to figure out this fuel leak!

Leaking form the bottom of the float bowls. Tomorrow I will take the carbs off and investigate gaskets, the couple I checked were fine visually.

I also pulled out one of the overflow valves from the bottom of the float bowl and it was just the needle screw, no o ring, washer, gasket or anything. I read another post that sounded like there was supposed to be an o ring in there. Anyone know if I'm missing an o ring?

Good info in the linked thread, havent tried it myself but might be worth a try before spending the 20$ on each carb for the oem gasket kit.

 

I saw that on the forum. Great idea. I used permatex gasket sealant. Working great so far.

As far as the drain screws I was missing an o ring seal on one of them, used a metric replacement - fuel leak solved.

Now time to change plugs and figure out the cct.

 

*Stupid question alert*
What do I need to remove spark plugs on my hurricane? Tried every metric and english deep well I have b/w 1/2" and 3/4.

 

You aren't the first person to puzzle over plugs.

This thread illustrates some of the trouble

so 18mm is the answer, but it sounds like you will need a thin-walled socket if not a dedicated plug-socket.
