Make sure you use a stainless clamp.
Something to think about??
I wonder why it blew?
Usually only a backfire would cause the split???
After the repair, use a can of starting fluid around the intake sides of the motor.
See if it makes any difference in the way it runs.
If the spray makes it stumble,run smooth or coughs?? Then it's got a bad gasket and sucking air.
The bad gasket can make it backfire??
Couldnt get a clamp to stay on it seemed to wide and would slip off. I used a ziptie and that worked. No more exhaust smoke leaks.
Bad gaskets you say.....?
Yea its possible. It coughs and sneezes quite a bit when i first try to start it. Then randomly itll do it throughout the day. At times itll fire right up with no sneeze at all.
When i started it recently when boot blew i had stored it as we moved. Maybe a month. First crank i primed the bulb and put throttle in fast idle and BANG! Sounded like a gunshot. Used the choke as usual. Not sure if fast idle start would cause backfire or cuz i hadnt started it in a while. Anyways...
Then the motor wouldnt start and if it did it wouldnt run long. I took off cover and it started right up. But didnt backfire that time. Put cover on and it stalled. Thats when i knew something wasnt right and upon further inspection saw the boot split wide open.
I installed a new one and took it out couple days ago. It didnt backfire this time but it took several cranks to get it started. Then it idled at boat dock and made it all way past no wake zone. Ran ok for few minutes to our spot.
I noticed carbs were leaking while out there. Out of the high speed jet or weep hole??? In middle carb.
The bowls were leaking too and the air plenum gaskets were soaked through and seeping a tad. Mounting gaskets are nice and sealed.
Took off the top carb when i got home and noticed two things. First is that the bowl wasnt parallel to the carb surface like its supposed to. The float is good and floats though.
Two....The needle was ok but i noticed it has a rubber tip. It didnt look deformed. But the part im not too informed about is the replacement needle with the correct corresponding part number does not have a rubber tip. I have a solid brass seat. Im not sure if i need a needle with a rubber tip or the metal tip will work with the brass seat???
And when you say gasket??? Which one would you be referring to? Any of the carb gaskets or like a head gasket, etc????
Thanks for the reply. I ordered a new gasket set and carb kit to see if any of it will help with the backfiribg/sneezing. Of course ill set the floats correctly as well.
The air screws are set to about 1 1/8 turns out and she smokes quite a bit idling but im ok with that. It stays idling for the most part. Just sneezes more than i think it should.
Any other input would be appreciated. Take care.
