I put this motor together...Machined 1984 block, new pistons/rings/bearings etc...Been running great. Until last trip.
For the issue, just tonight I swapped the VRO/Fuel pump unit with another (I mix), and did a complete carb rebuild properly( Berrymans, wire and air). Will test tomorrow.
THE QUESTION: I found the original floats bent at a decent angle, where the bowls would probably fill with a lesser amount of fuel when the needle shuts off the supply.
THE SYMPTOM: Would bog and try to die only once at planning speeds 3000-3500 after 15secs or so. Backing off the throttle to idle for just a couple seconds would allow another short run. YES, squeezing the bulb, or hitting the primer--WOULD DEFINETLY ALLOW it to run at speed. I could actually keep hitting the primer and continue to run, sort of.
This is not a Tempature issue, as I monitor closely..I know these motors pretty well. I am currently using double oil during my breakin, due to the new pistons and rings. The carbs were original 1984, and personally I hadn't rebuilt them before last night. They looked clean.
CAN THOSE BENT FLOATS DO THIS: A short run, then run out of fuel until they fill up again??
Thanks
