1985 70hp Johson VRO

[cchinchak]

My problem is the engine bogs down and stalls when trying to open up the throttle. The VRO has been disabled and now using premixed gas/oil. Compression and spark are both good. I figured the carbs needed to be cleaned so I took all 3 off. Then I noticed that the hose to the oil nipple on the bottom of the VRO fuel pump was disconnected. Will this cause the the motor to stall and die when trying to open up the throttle?
Thanks.

if that is not blocked off, it will pump air into the fuel mix. just put a short piece of hose on it, then a bolt, plug in the hose and a hose clamp. clean the carbs any way. especially the low and high speed jets.

Will that air being pumped into the fuel mix cause it to bog down when trying to go faster? It idled fine.

Thanks.
