Having problems with the motor running at high rpm. I had just replaced the fuel pump, cleaned the carb. Has anyone seen this before with the style motor can't seem to figure it out i have a feeling it is like a rev limiter which in theory would be the power pack.

I had trouble with your link above. Is this your video?...

It may not be a problem as your motor doesn't have a load. You should only throttle that high on the water.

Do you also own a Jap Sport bike? Those guys do that all the time as well.

That engine was never designed to be run like you just ran it.
It is the limiter kicking in and from the way it was run ..... its a good thing it was there.
Put it in the water and run it, on the boat, away from the dock, in gear, and actually pushing the boat. Figured I better spell it out for you !
Yes, the last part was a bit of good natured fun!
 
Reminds me when we were kids. Take a junk car and run it in neutral with a cinder block on the gas pedal. Wait for the funny noises.

Missed that video link...


A bigger prop won't help unless your out on the water...in a boat...in gear.

He had it on land, on a hose. Put it in gear and went to WOT...............
Say it aint so........ Good way to blow one up

WTH , :LOL2:
 
Test it a few more times and that will more than likely put an end to the surging, but you may not be happy with the reason it doesn't run.... I mean surge any more. :shock:
