Hey everybody. So I have a 2013 Puma Apache, manufactured by ZNEN, and it's been great so far. I know people like to rip on Chinese scooters, but I've been more than happy with the build quality, considering the price. Some of the hardware and vacuum/fuel lines were obviously bad quality, but they've been replaced.
Anyway, I recently replaced the stock air box with a UNI air filter, and changed the main jet from a stock 110 to a 115. I also switched the engine oil when I changed the air filter, about 200 miles ago. Everything else is stock, except for an NCY ignition coil and iridium spark plug (NGK brand CR7HIX). After I changed the air filter, the scooter has problems warming up. It starts perfectly, and runs great once the engine is hot.
The only problem is that I have to start it 3 or 4 times while its warming up. I always start it in the garage and let it heat up for a while before driving it. It'll fire and start, but after 30 seconds or so the RPM's drop, and it dies. So I'll start it again, and it'll die again. But after a few rounds of this, it runs like a dream. It's not really a major concern, just annoying. If I hang out and pull the throttle a bit through the warming up process, it won't die. What could be causing this? The oil I'm using is Royal Purple 10W-30 for 4-stroke engines, and Royal Purple gear oil...if that matters. The scooter has about 900 miles. I bought it brand new and broke in the engine properly (as far as I know).
I've checked the carb float, it moves properly and isn't clogged/blocked/damaged. Same thing with the auto choke needle. I've torn apart and cleaned the carb with cleaner and compressed air a million times, but no dice.
Thanks!
