Perfect, thank you everyone for the help. It means a lot. I can finally says it’s ready to race.

[David hofflinger]

Alright I fixed it, come to find out it was the starter and bad battery. The only question I have now is why it won’t keep running if I let off the gas, I have the idle screw set up but the motor dies as soon as I let off. It’s a 2 stroke and I know a lot of guys who race dirt bikes don’t want there bikes to idle at all.

[David hofflinger]

Okay, so I had the kart running and stupid me forgot to put the small o rings on for the cylinder head bolts…Coolant leaked out while running and went into the cylinder and stopped the motor. Now I dried everything out and now the motor will only turn over…it won’t coma bust so I’m back to squar one. And today after I’d crank it the starter stopped engaging…I assumed it was a bad battery and bad starter so I got a new starter and battery…still doesn’t work. The motor turns over but the starter won’t engage to grabs the clutch. In all honesty I’ve never worked on anything so temperamental and confusing.

[David hofflinger]

GOOD NEWS! I got it running. I still don’t know how but I tried the old spark plug and it started right up. For some reason the new plugs were not working and I know…it’s strange.

[David hofflinger]

So I’m getting spark and I tried choking the motor, I’m getting nothing still. I even tried starter fluid right in the cylinder and nothing. I’m at a loss for words. Carb seems to be sucking in gas. Everything is lined up.

[David hofflinger]

<p>I just send back the cylinder I got on eBay, the one that was too short, the guy actually shimmed the top of it off and didn’t tell me. So I dropped the old one back on just to see and it turns over fine now. Weird. And Walt, you’re in Bridgeton? If I need help I’ll contact you somehow</p>

[David hofflinger]

I found out it’s the new cylinder. It’s a hair to short for some reason and making the piston hit the head. I’ll need s thicker gasket and then it should run. S

[David hofflinger]

Now I put the motor and everything back together again, new issue, the kart won’t turn over now. At all. It looks stuck

[David hofflinger]

If only there was a kart mechanic around Vineland New Jersey lol

[David hofflinger]

Like, even when the motor turns overs the gas doesn’t get sucked into the motor, just sold out the carb. And it won’t even attempt to combust, it just turns over. Can choking it be the cure? Also before I rebuilt the motor starting fluid started it right up, I tried spraying starting fuild into the carb recently after I rebuilt it and I got nothing. But tomorrow I’ll attempt to choke it like you said and hopefully that’s the problem.

I did not choke it though, the only thing is when I bought the motors used before I rebuilt it, all I had to do was spray the starting fluid in the carb and it started right up. I’ll try to choke it like you said. I’m hoping that’s the issue. </span>

[David hofflinger]

What is the crank trigger magnet? I got a magnet that goes in between the stater, but it doesn’t fit properly on my crank shaft, the original magnet fit but the new one the kit came with is bored way too big

[David hofflinger]

I never thought of choking the motor like that, I’ll let you know once I try it. Thank you all for the help

[David hofflinger]

I actually got the key ignition kit from comet kart sales. Came with everything

[David hofflinger]

Sorry I thought I deleted that comment, it’s a Leopard I just measured wrong sorry

[David hofflinger]

Yep, everything went together and plunged in the same way it way before. Just after the rebuild no fuel is being sucked up into the motor, just the carb. And the carb is fine so I still can’t figure it out. I guess once the new piston comes in I’ll see if it actually was a compression issue. I also tongues everything to specs so that may have been another issue before

 

 

 

 

[David hofflinger]

<p>My bore measured 53.47. I can only find Pistons starting at 54 on Comet Kart sales.</p>

[David hofflinger]

I did that, no combustion. But the piston and everything is working how it should. It went together exactly how it came apart.

[David hofflinger]

I’m thinking its to low of compression from the old piston and ring. Maybe when I put it back together it’s too low now and it won’t suck up the gas through the carb

[David hofflinger]

The clutch is good and yes I rebuilt the whole bottom end, seals and everything. Just didn’t put in new a piston or rings. So I’m thinking its low compression that’s not letting the gas pump up to the motor. And the carb is in good condition everything’s clean and working.

[David hofflinger]

I’ll Che k that tomorrow. Also, what does it mean when I look for a new piston and it says Red Dot or Blue Dot?

[David hofflinger]

<p>I was just asking if that’s how this carb works, again I’m new to this. But if I had a kart mechanic anywhere around here is definitely go to them. But until then I’d like to try to figure this out. All I know is fuel is not getting into the motor and no combustion, but there is a spark. If you guys are as stumped as I am I don’t blame you. </p>

[David hofflinger]

When I push the throttle should anything move in the carb up or down? Because nothing happens. I’m just taking guesses now.

[David hofflinger]

<p>I checked my carb again and it’s all together right it looks. It’s still not sucking gas into the motor. I’m honestly stumped. My last resort would be to take it to my local track and get one of there mechanics to mess with it.</p>

[David hofflinger]

<p>Fuel is being sucked up only through the carb and back out of the front of it. Not even making it into the motor and I checked all the holes and everything and it’s all lined up. Did I put the motor together wrong? Maybe I didn’t torque the bolts to spec? </p>
