Won't start
Hey guys, sorry for a total newb question but I'm stumped. 85 spree won't start.
Getting gas,
I cleaned out carb multiple times (made sure all micro holes open), it's getting spark,
good compression.
Will start if I squirt gas/oil mix into cylinder. Once started in that fashion it will stay running but it's an extremely high idle so I don't usually leave it running for more than a few seconds. Please help!! Thanks in advance

Re: Won't start
Check the petcock, make sure you have vacuum going to it and that it isn't clogged. Make sure gas comes from the fuel lines when vacuum is applied.
Re: Won't start
Yes, petcock is operating correctly.
Re: Won't start
sounds like throttle valve came in wrong way, or not seating well...
Re: Won't start
Betting your slide is in backward, or cable is hung up.

Re: Won't start
Hung up cable sounds right, as throttle feels very odd...almost stuck open. I assume that would affect starting? I tried removing the throttle valve, plugging the hole and then attempting to start but it didn't even feel like it wanted to start at all.
Re: Won't start
Did you read what noiseguy said and checked ?
There is notches in the carb that guide the throttle thing down

Re: Won't start
Yes, it is properly aligned. Cable seems to not be hung up. but would stuck throttle make such a difference when starting that the scooter wouldn't even "try to" start at all?

Greetings:
Uhh, yeah. These things start on the starter "enrichener" only if the throttle is closed. Adding that much air entry area with a throttle stuck open results in the inhalation of an uncombustibly lean mixture. It MIGHT start, eventually if the engine friction-warms enough, but if it does you'll be scrambling for the Kill switch because it'll rev to the moon.
