Fuel primer bulb issue Q.

2 posts in this topic

The boat is a 1997 Pro V and the motor is a 1997 Johnson 115 Fastrike. The issue I have is after running from the landing to the fishing spot and sitting there for 30-45 minutes, restarting the motor turnes into a start/die, start/die situation until you reprime the motor. The primer bulb goes soft sitting there for that little while. The motor starts and runs fine cold.

I changed the primer bulb and fuel inlet hose earlier in the year and that didn't help anything.

I don't know if this a related issue or not but after the motor is started (restarted after it's warm) you kind of have to baby it get into any throttle above idle. It kind of acts like a (I am really dating myself here) like back in the day when vehicles had carburetors and the accelorator pump was bad. The motor runs great at WOT once you get there and after you get thru the off idle issue it pulls real strong.

Can any of you 2 stroke masters figure this out?

By the way, the gas is good and has sea foam in it, compression is within 3 psi of each other.

I'm guessing it's time for a fuel pump (in this case VRO) rebuild - it doesn't have enough vacuum to pull the fuel up to the tank - and drawing the primer bulb down is one of the big symptoms...

      Most of our fish came on minnows under bobbers. I spooked countless fish with even subtle jigging.

      Hey, Here a quick update on actual ice thickness or snow cover on trout. 14 inchs of ice pressure ridge out there. if you are  on a snowmobile if traveling fast on it watch for it. Truck or car i do not recommend on trout with pressure ridge. And yes i have been on the whitefish chain this year in truck. just not on trout. just my 2 cents

      Thanks for the info everyone. And Borch that is good to know too.  I try to spend 2-3 hours looking on cedar each trip, but It's a lot of water to break down , and having only been out hardwater cattin 6 times so far I still have a lot to learn.  Generally I spend a lot of my 3 hours losing confidence and then wind up at the meth hole to catch a few .  Putting in the work is what makes it so fun once it all comes together though!
