Problem with my 77 50 hp suzuki

[rcthd]

Ok here is the problem.

The other night I was out on the lake. I stopped and started the motor about 3-4 times no problems then on the next time it would not start. The next day I put in new plugs and it started just fine.

Now last night I was on the lake driving anound and the motor just stopped. I pulled the plugs and they looked wet, so I am guessing that the motor if flooding out. I put the old plugs back in and I got it started and went home.

Is their any adjustments on these carbs that I can try?

Motor history: There is a newer electric system on the motor.

I have replaced the gas lines, tank and added a filter a couple of years ago.

This motor has sat a couple of years without being started so could old gas/oil be the problem?

edited to add: that I am useing new gas but when last ran it was not foamed ect.

Any ideas?

Thanks

Rick

Not sure if this the same problem as you are having but mine was similar. Would start cold no problem, would start fine if I started it again within 20 minutes or so, but after that it would be a real PITA to get it to start. Sound similar to what you have going?

What I finally wound up doing is rebuilding the carbs. It would seem that the needle and seat was not sealing the bowl and the gas was seeping down into the cylinders and flooding it out. After the rebuild it works fine. I did my own so it only cost me about $75 for the kits and it was not that difficult to do.

It may be what you are experiencing. Then again it may not be.

You need your carbs rebuilt after sitting for such a long time, that will solve the problem.
