Here's what it does. starts easy, idles great and accelerates to full throttle fairly quickly. once it gets to full throttle or sometimes just before it will "bog" then immediately pick up run fine for anywhere from a few seconds to a couple minutes and do it all over again. It also will occaisiionaly do this at maybe 3/4 throttle.
The oil side of the VRO was plugged off by a previous owner.
When would you look first, the fuel pump or carb floats? Or is this perhaps not a fuel system problem??
I can buy a new non VRO pump for 100 bucks... but the parts house tells me there's two types I can use.... one that mounts to the crankcase and gets it's vacuum from there and one that I'd run a hose to the existing port on the crankcase that feeds the installed VRO pump.
If I got the one that mounts to the crankcase... where would I mount it to get the vacuum? Is there a port somewhere that's got a screw in it or something??
This engine has power pack that's not 3 months old and new coils...
Obviously I'm no expert or I wouldn't be asking questions here... but it would seem logical to me that the fuel pump isn't keeping the carbs supplied with enough fuel..... but then again once it bogs it recovers within a second or two...
I haven't tried running it on the hose to see if it does the same thing without a "load" on it other than the prop.... but thought that might be a useless test?
