First question since i am assuming it was just sitting around for some time if i am correct you need to pull the carb remove the float bowl and components if everything was done correctly with your rebuild the likely problem is your carb is gummed up remove everything in the carb low speed jet etc. soak everything in sea foam fuel cleaner overnight and hopefully you have some compressed air and blow out that low speed jet and passage way pay close attention that you have see fluid coming from the other end and check the jet make sure it is unclogged hold it up to the light.

NO! Check the boot between the carb and engine. Very common problem for aged rubber is non-visual cracks. Pull it off and check the boot by kneeding it and looking at it under a light.

70lbs for a 90cc should be good, but 80-85 is better. Compression drops from piston rings wearing out, most of the time. Piston rings wear out from old oil...every time. Rule of Thumb: 5 tanks of gas, change your oil !!! It's not a car !!! A car has 5 quarts of oil which takes about 3 months to break down (2,000 miles or so), 90 cc engine has a half a quart, which takes about 3 weeks to break down (based on everyday use) SO...5 tanks of gas, change your oil..
as for the not starting thing, check for spark (should be a blue spark ONLY, any other, replace plug, orange won't ignite gas) if you haven't been riding for a while, open the drain screw on the bottom the carburetor and drain the water out. Ethanol turns to water when the gas sits too long...

have 04 polaris predator 500 doing the same thing, when giving full throttle it seems to be hitting a limiter a couple of 1000 rpm below full rpm, but will only start with air box disconnected from carby and spitting gas out, might be buggered T.P.S unit have bought new Keihin Flat CR carby with T.P.S on it so to replace one on thumb throttle as it has taken some knocks ( should be able to test T.P.S with volt meter when pushing the throttle), a cdi unit and coil will see how that goes.

I dont have a solution but mine is doing the same as the posted ones--runs at idle but bogs down with fast fuel feed!! does anyone know the solution?
SOURCE: what do I need to check
Oil level good ? Fins on head clean? Or could be electic componets braking down due to heat start with checking resistance at primary coil
