Hey guys! LOVE this forum. I read through a bunch of Carb stuff on tips to get them off, came in handy today.
1) Bought bike from an OLD guy who gave up, it had been sitting for maybe 2 years, gas is apparently 1+ year old and he put a can of seafoam in there (I added one myself)
2) Inspecting the carbs I noticed they looked wet, it had just stormed. Tried starting the bike, VERY slow crank, sounded like sticky pistons.
3) Brought bike home, pulled plugs, added seafoam, hit the starter 10 minutes later and no stuck pistons! Cleared the seafoam out. Added new plugs.
4) Tried starting the bike, it starts!!!! Only when holding the choke all the way open. I did get it down to like half but she just dies out. Any throttle will kill the bike.
5) Pulled Carbs, cleaned them -- very dirty, found a mud wasp (dead)! - used carb cleaner + air hose and blew out everything I could see and find.
-----------
6) Carbs reassembled (omg that sucked), tried starting it - no start. I think the battery might be tired as I accidently hit the kill switch lol, spent 30 minutes on it, checking spark etc only to notice later. Battery is now at about 11.8 volts.
7) I was able to get it started on full choke when I added my battery booster but that too is dead! Farts. Currently charging everything and waiting impatiently to see if my $600 dollar bike will live!
QUESTIONS:
- The old gas: I'm thinking it might have water / moisture, I think I'll drain the carbs tonight and suck the gas out, replace with new gas just to eliminate this issue all together. But as it started on full choke and ran for 3 minutes shouldn't the gas be OK?
- Battery at 11.8v: It does have enough juice to start it for a second but I can hear it spinning slower. I know on snow mobiles you gota have a FULL battery to start. Same thing here?
- I'm not exactly sure where the pilot jet is for idle, 99% sure I cleaned it. I took off a part in the float bowl that had a gasket, they did tear in a few places but I'm not super concerned as it was only on the screws that held it down. Would this torn gasket result in no start?
Summary: I feel like carb is fine, I've cleaned a lot of them now lol. I LOVE the metal float needles omg why isn't that a standard... Fuel is running fine. Hoping it's just weak battery. Would love to hear your thoughts! Cheers from Canada.
