TRAILMASTER XRS 150. Won't start.

[Mydive2]

Installed new stock carb, fueltank valve, hoses
and filter and fresh gas. Started right up, ran like a champ after installs. Next day, will not start. Getting plenty of gas at carb fuel inlet. Cranked and cranked. Pull plug to check for spark, which it does have , but spark plug dry as a bone.

This subforum is just for saying hello and is one of the least popular places on the site. Go Kart Discussion gets the most traffic and views than anything else. Copy and paste what you wrote into a new thread here: https://www.diygokarts.com/community/forums/go-kart-discussion.6/ and some photos of your kart, engine and carb would help.

Anyway, you basically stated the problem right at end--you're (probably) not getting fuel. Carburetors are not idiot proof, they are analog science and they rarely come properly adjusted right out of the box....

Sounds like the carb may be dirty again.

I found that it will start with a squirt of starting fluid. It will continue to run full rpm range for as long as I wish. Ran it for 1 hour before shutting it off. It would then restart repeatedly. Let it set for 2 hours, would not restart without squirt of fluid. .Apparently no problem getting fuel, has compression and Ignition.
