[QUOTE="14altra, post: 482659, member: 28091"] This is my first small engine motor Im used to larger outboards. I bought a new tank put 2 gallons of fuel and 7 oz of oil which should be 40:1. I may be running to rich but I didnt ant to chance it. The cowl shows 16oz for 4-6 gallons of fuel which is 30 or 40:1. 7 is between 30-40 to 1. The problem is the engine wont stay running. I can get it to start but after 4 or 5 minutes it dies. There are multiple adjustments on the front. Choke, idle, and high speed. I set them all at the suggested settings under the cowl and it will start and run and I can even push in the choke and I seem to be able to smooth it out with the high speed setting. One thing I noticed is that I cant get the primer bulb to get firm. When I pump it fuel comes out of a little hole in what I think is the fuel pump. The bulb on my last outboard, a 90hp mercury, would get rock hard. I dont think fuel should be coming out. Someone told me its an overflow/pressure relief so you dont rupture the pump diaphragm. Any help would be very appreciated. I would like to be able to grab an hour or two fishing once in awhile. I have pics but I dont know how to upload them. [/QUOTE]
