Hi everyone,
I recently got my PK50B engine and I've gone about 65 km on it already (about 1 and 1/4 tanks of gas), it's incredibly fun, but I'm a little concerned. Here's why...
Ever since I got it it has been 4-stroking. Since I'm a sucker for engine noise, I think it actually sounds pretty good as a 4-stroke, but I want to find out why it is doing it.
It only works properly when I go uphill or on loose sand when it's getting a hard workout. Wiring seems OK, I had soldered the blue wire to a kill switch, but the black wire is not soldered yet. I don't think that's the problem because it works fine under load.
I am absolutely sure it is not running too rich. In fact, for a while I actually had it running much too lean because I thought that it was too rich. The spark plug was pure white after a 20-minute run and the silver finish on the engine had even got a bit yellower from the lean heat.
Any help would be appreciated.
Jess
