Dudes, Everything was fine till It stalled after a highspeed run and when it came down to idle, it stalled. Now I can't start it again...! Help...

Maybe you are running it alittle lean on the top and the plug burned out, check it, I bet that is what happened.

I checked the plug and it's A OK

how's the compression? Also sometimes you can get vapor-lock after a speed run, carb gets hot, and the fuel boils when it gets to it. If the plug is good, and you are getting fuel, then compression is about the only other thing to check.

I am having the same problem too. HSN almost 4 turns out. It was running fine until WOT. Then I can't start it. I have to remove the fuel line from pipe to tank then it will start again. This is so weird.

It still sounds like it's running hot. Do you have a temp gauge? If so, what's it say at the glowplug?

You may have an air leak in the backplate, fuel line, fuel tank, carb neck, exhaust coupler and/or header gasket. An air leak will give you high temps and erratic running regardless what you set the carb at.

This engine has not passed 200

Dude, I think the spent gas from the pipe is leaking back into the engine. I took it to local LHS to have them check it out. Hopefully they finish before race day... Did yours come with the carb settings really rich???
