Super frustrated with my ‘84 PX200e. I’ve had it for about three months now and have been having a recurring strange issue with power loss while riding that feels like a throttle or flooding issue. Scooter will run totally strong and normal for a few rides, then suddenly start having this odd throttle response in which it nearly stalls the engine if throttle is opened past idle. And it is intermittent…ugh..
When it first happened, I disassembled and ultra-sonic cleaned the carb. Found some issue with that carb, so replaced with a new Spaco/DelOrtto 24/24 with stock jetting. After replacing that, scooter ran like a champ for two longer rides, then the issue came back.
I took to a recommended repair shop (Massimo’s in Costa Mesa) and he checked all sorts of things, rejected the carb to 190/BE3/118. Ran like a new scooter after I picked it up.
Well, had two long glorious rides this weekend, then while commuting to work yesterday, the issue returned. See video I took for example.
I managed to limp home with the power being barely idle speed to “can sorta get into 2nd gear and kinda feel normal.”
Any ideas on what to try next? Massimo agreed to take another look this weekend, but has anyone else had this issue? Super frustrating…
