Why when i rev out in gear does it just drop off,then i let off and it picks back up? just started this little mystery today. i was just running around in the yard with it.would it do this if it was a little low in oil? Thanks for any advice..Gary

If it is losing power when on the gas it could be a fuel flow problem.

I have a new fuel pump and filter,is there anywhere on here that explains how to "open up" those quick disconnects? it does like the carb would do if the bowl ran out of fuel

I took the 2 connects off the 2 fuel lines put them in a vice and drilled out the white plastic inside the flow hole. Then blew air through them to get remaining plastic pieces out. The other ones are on the tank they just screw out of the tank. Take those and also drill out the white plastic inside of them, also make sure you pull out the o-rings that are in the center of the tank connects. Then just reinsert back in tank using teflon tape and your good.

Ya, the quick connects are too restricting and the o-rings swell with time, and gutting them lets the pump run free-er.

If you want the cat's meow then boomer's tank conversions are sweet and really quiet the pump down. Some say you will never have a pump failure afterwords.

I thought that fixed it, but took it out for a ride,and about a mile down the road it would just run out of fuel. i would let off the gas and let it idle or shut it off and after a minute or so it would start up and run like a champ. i did notice after i shut it off there were air bubbles steadily flowing through my fuel filter. after they stopped flowing i started it and i couldnt get it to run out of fuel again. i prob made it a mile before this started. do you think when i first run it for the day,it has an air pocket? where would the air pocket be coming from? Thanks for any help...Gary

I blew through the vent tube it was clear.just cant figure out why when it runs out,it has way too much air in the filter. you can see bubbles constantly flow through the filter for about 45 seconds. then its good to go.could it be sucking air at the quick disconnect?
