Hi all, new to this forum.
Short story: '71 cb450 motor and only the necessities to start, kick started fine the first time, and it idled fine. Next, tried the starter motor, didn't work, gas shot from air jet. Kick start is now verrryyy difficult to turn, and it doesn't spring back up anymore. Pistons move up and down with no problem.
Help?
Long story:
I recently picked up a cb450 motor (just motor and carbs), and then some. I plan on using it for a country yard go kart - so budget is low. I was told it had been sitting around for a little under 10 years. Anyhow, I went the cheap route and got universal coils and condensers to get the engine to start. I greased up the cam lobes and put in fresh oil, cleaned the carbs and such. Hooked up the coils and condenser, etc... I mocked up a wood frame to hold the engine while i tried to kick start it.
A few kicks later it started and idled perfectly fine, but without headers, i turned it off after a minute.
After i was sure it could idle, I wanted to make sure i could start it with the starter motor since I didn't want to deal with kick starting it on a go kart chassis.
I hooked up power to the starter motor, nothing happened just slight whirring. It was a very old battery that I let charge earlier that morning. I figured the battery wasn't fully charged or giving out enough current. I tried to jump start the motor with my car; this time, the starter turned the engine over a couple times and the carbs SHOT gas out of the air jet. I let the starter cool for a few minutes, tried again, and same result. The starter motor is hooked up properly, and the starter clutch rotates freely one way, and restricted the opposite way.
So i go to kick start it, and the kickstart will not move as easily as before, nor will it spring back into place. Also, one of the carbs is spewing gas out of the overflow, so I'll have to check the needle and such.
I've tried to turn the crankshaft via the flywheel bolt, and it turns fine clockwise(? don't remember). The crankshaft will only turn a 180 degrees before it will get really difficult when i turn it counter-clockwise.
Whew! that's a lot to read. any help? Thanks.
