My leaf blower has started giving me trouble lately. It slows down at full throttle
It runs fine until it gets warm, maybe 5-10 minutes then it starts slowing down at full throttle every once in a while until it gets progressively worst and eventually I can't get it to run at full throttle. I can keep it running by letting off the throttle for a few seconds then returning to wot. the problem is intermitent so I can get the job done it just takes longer.
I checked the screen in the exhaust but it wasn't very dirty. I also took the carb off and sprayed it down with carb cleaner. found out it is a strato design and the strato barrel valve in the carb had a bit of oil mix in it so I sprayed everything inside and out with carb cleaner without disassembling it.
I did a search and found out it has reed valves so maybe something is wrong with them but other than the basics I have no clue where to start. The plug is a nice tan color with a little carbon buildup. no obvious fuel leaks, fuel filter is new from last year.
Where do I look next?
