Are you flooding it?
Is it getting enough fuel? Air bubbles in the lines?
Where are your needle settings?

I say return the needle settings back to stock, pull your carb and clean it out, could be locked with fuel, my Jato had a problem like your saying, so i wasen't home to fix it and had my GF take it to the hobby shop, he richened the needles 5 turns, cleaned the carn out because it was hydro locked with fuel and it started right up and ran great. Might have the same problem.

SOUNDS like your truck is flooded though, if it's that tight you have WAY to much fuel in there, pull the glow plug, flip the truck upside down and spin the starter and fuel should shoot out, keep doing that till no fiel spits out and then try to restart it. DO THIS before you take apart the carb.

ALSO check your glow plug to make sure it's lighting, along with making sure your igniter is charged fully!

Hi. Beware of a loose plug, if you loosen it too much you probably won't be able to start it either - I know mine wouldn't.

the carb. is at factory setting , the glow plug and igniter are heating up fine. And cen recomends that you loosen the glow plug to get it started.

After breakin you should not have to loosen the plug.

I figured out the problem first i changed to a os#8 plugand second i use my drill to start to replace roto starter. And tighten glow plug .

THANKS FOR ALL THE HELP
