Is it in neutral?

 

[Phildoo]

No. It started doing this while on the lake the other day. It feels like it loses spark under load..also getting fuel spray out of front carb back out of the throttle body.

i'd start with new sparkplugs. Check the oil return for sparkles from the rv gear.

 

[Phildoo]

Yea, plugs were the first thing I did..right on the lake. Not sure where the oil return line is. Anyone have a photo?

 

[parrothd]

Ugh.....

I'd do a compression test, and make sure the rotary valve is still turning, and check the simple things like plugs/wires..

 

[Phildoo]

Compression is dead on 150/150

 

[parrothd]

Not sure if you have enough room, but look down the carbs with the throttle open and see if the rotary valve is still moving. I'd take the plugs out and rotate the engine by hand, may be easier to take the carbs off, and or the carb intake, or use a mirror...

 

[seadooya]

try clipping the plug wires. You say you went thru the carbs, is the excel pump squirting? Did you pull the raves, make sure they're clean, then install new plugs? Use a mirror, make sure the brass oil fittings are still protruding thru the intake? If not, then possible, it ground a groove from port to port holes....

Clipping the plug wires??

 

[seadooya]

pull the sparkplug boots, bro. They pop right off, clip the wires 1/4in, then insert boots back on. thread them back on though

Sounds like it's on the rev limiter. Limp mode? Overheating?
