To test the compression on one of these engines with a gauge, a 10mm adapter must be used. A standard spark plug is 14mm. You can possibly use the gauge with the rubber insert you shove into the spark plug hole; otherwise your compression gauge has to have the smaller 10mm adapter included to accomodate the small spark plug size. I do not know if the loaner kits at the auto parts store include the adapter.

ok so i kept fooling around with it today and i finally got it to start again... im almost positive that its a bad ignition coil. i wiggled it around and it finally started again a few times today. but still wants to die at idle. i sucked all the old gas out of it with a shop vac and put some ethanol free gas in it. the oil was black as tar. so i also changed the oil.

but yes it is beat up a bit. and has been sitting for a long time. and another issue with it... so i purchased a new starter relay and a new starter switch.. and i still cant engage the starter with the button on the handle bar. i have to jump the relay with a screwdriver to get the starter to work.

I bought a 98 Zuma scooter that sat for around 1-2 years! Carb had rock hard varnish in it and the tank was a nightmare! I managed to salvage the carb, mostly because we have a industrial parts cleaner at my job, and I cleaned out the fuel tank 3 times total. Also replaced the fuel filter just because it was cheap and easy to get at. Scooter runs like a top now! Sometimes the plug boot/cap gets a damaged spring holder and does not make good contact. It will stall at idle. My Adly had it break in the first 100 miles. I have it kinda rigged now but it has done around 1000 miles now with no issues. Now, other issue. A weak battery will make it hard to start, sometimes not even letting the starter engage. Did you put a new battery in it or was the one with the scooter still good? At the price you paid it does not seem that bad a deal. Cheapest I ever let a scooter go was $400 for a nice and clean 08 Zuma 2 stroke. Still kicking myself because I wanted $750 obo. Long story but I honored the price. Helped someone out and went to a good home, plus I broke even on the deal. Shop Vac and fuel? Wow, you got LUCKY you didnt blow up!

My 98 Zuma was sitting, like I said, for 1-2 years. I got lucky though. It was kept in a climate controlled garage and it has drum brakes. Im a small engine tech for a living but dont work on or fix them, I just test them for emissions compliance. I do build 2 stroke scooters and mopeds for fun, see how fast you can get it to go without falling apart. If I cant figure something out or run into a weird problem my boss has a Dr. degree in mechanical engineering/small engine technology. Now onto your scoot. I bet the window for the brake fluid level check on the front brake master cylinder is leaking. I have had it happen and it sucks! Agree on getting it running first. Keep us updated and dont hesitate to ask questions!
