Still not getting fuel? What else?

[Banny&RappyGuy]

Ok, carbs are clean( boiled and spotless) , I have new Reeds, I have 125 compression and there is fuel in the carbs but it's not getting pulled through. What else can I check for? I've kicked it with choke and checked the plugs after and they're dry. If I put fuel in the head it will start and stay running?! Anyone else have this happen? This thing is driving me crazy

Did you use compressed air and cleaner for the jets? How about your petcock? Does it flow gas through it fine? Are the floats suck in the carb making gas just poor out of them? How about the gas cap vent? Is that plugged up?

Choke tube on?

Bowls on the right sides?

float height checked?

[oldskool]

^^^ That. choke tube connected? Floats adjusted properly?  Any air leaks?

Did everything I can think of, used compressed air to clean the carbs and all the jets, did a leak down test, carbs are getting fuel, bowls and slides are on the right carbs, choke tube is there and good!! Like I said I don't know what else it could be? Mind boggling to me?

Have you recently replaced pistons? I have seen them installed backwards and that would cause the exact same problem.

[Banny&RappyGuy]

No, I haven't changed the pistons. It'll run great if I get it started. It just won't start after it sits.

It sounds like a compression issue.

A lot of blow by will just eliminate the vacuum in the cases. Have you used more then one tester to eliminate a faulty tester?

[Banny&RappyGuy]

ACTUALLY DID GET ANOTHER TESTER TO MAKE SURE AND THEY BOTH READ THE SAME, 125PSI. THE THING I CANT FIGURE OUT IS THAT IF I GET IT RUNNING IT'LL PULL FUEL AND RUN GREAT. IT'LL START UP AFTER THAT TOO UNTIL LIKE THE NEXT DAY OR IT GETS COLD KINDA THING!!!!

Stock carbs? Check the o ring on choke. Maybe it's just not bringing the choke circuit in. I'm assuming it runs fine after it does start??

X2 very good chance it's a choke problem..

[Banny&RappyGuy]

It runs great once I get it started!! Also I fired it up this morning( with some help) and I took the choke tube off while it's running and it revs up quite a bit,, put the tube back on and it idles down to where it should be. Is this normal??

The choke plunger o ring. It will unscrew with wrench from the left carb.

Yes, because without tube you have created an air leak=lean
