Needles should be flush to one hour out on top and 1.5 turns in on bottom. Heat it with a heat gun to 220 deg. Not sure why your fuel is going backward, maybe make sure the box is turning the right way? Also a hotter plug helps but I broke in 2 .25's 2 weeks ago and one used the Go #6 plug with no prob.

Check the pressure feed nipple on the exhaust pipe. I had pipe once that had a blockage in there. No pressure was getting to the tank. Poke a piece of wire down the nipple or blow through it and make sure it is clear.
If it's blocked you will be running super lean and engine will start but won't keep running more than a few seconds.
Sometimes the fuel will squirt out of the carb throat when starting. Don't run your engine without the air filter for long though. Any dirt or dust down the carb throat is a recipe for disaster

By "pushes out of the carb", you're saying it flows backward away from the fuel intake nipple right? If this is what's happening, it's very likely a pressure problem like Grizz1 was suggesting, and it could be any part of the pressure system. Check very carefully: the header nipple(read Grizz1 notes), fuel tank lid, pressure test fuel tank, exhaust gaskets/seals, replace fuel tubing if it's not brand new.

Rod for 5port
 

What's the part number for a 5port connecting rod? I'm about at the 2gallon mark and I want to replace it.
thanks

I will check that out. How do I pressure test the fuel tank?

Just some awesome advice in this thread as usual.

What's the best way to get a sleeve out (without destroying it) that refuses to come out of the crankcase even when heated. Is there a tool out there besides the one's that cost as much as a new engine. (ex. GRP tooling kit $179.00) I want to replace the rod and wrist pin in my 7 port. It has about 2 gallons through it and I can tell the rod is shot. There is still lots of compression in the engine and I want to use it still.

Its best to attach a flywheel to the engine and tighten it down. heat up the case a little and place a fairly large zip tie thru the exhaust opening. Then turn the flywheel and force the piston up on the zip tie, it is ok to use pliers on the flywheel. Once the sleeve is popped up slightly i like to spray a little wd-40 onto the sleeve and slowly and very very carefully pry it out with a screwdriver, be sure to work your way around the sleeve and remember to be careful, once you can get your fingers around the sleeve grab it with a shop towl and pull it out.

+1 for the zip tie.

Just to clarify I put the zip tie down from the top of the engine and put the Knuckle of the tie into the exhaust outlet then turn it over with the flywheel,
not in from the rear of the engine through the exhaust out let as I find it's easier to keep it where you want it so it doesn't slip in to far a get sliced off by the piston

Hi El Tigre - Take your fuel tank out. Make up a plug with a small piece of fuel tubing bent over itself and clamped together using a small cable tie (also handy for plugging the fuel nipple on your engine when it's out for maintenance etc).
Put this plug on the nipple that comes out of the tank itself. Connect a length of fuel tubing to the pressure inlet nipple on the tank lid.
Now fill your kitchen sink (best do this when the lady of the house is out of sight :) ). Place the tank entirely under water and blow into the fuel tubing connected to the lid. If any bubbles come out of the tank you have a leak.
Most common places are around the sealed edge where the two halfs of the tank are joined, or from the lid due to a faulty "O" ring or a weak spring. If in any doubt, replace the tank. They are not expensive and it's safer than trying to glue up cracks etc.
Be sure to thourghly dry the tank off and flush some fuel through the tank before using it again. You do not want even a hint of water mixed in with your fuel.

Makes sense. Thanks for the info. I will do that tonight (and wait til the missus is gone).

I've got a Losi 8ight. I'm looking at putting an .21 7-port standard plug in it. Whats the best Dynamite for it? I've heard the 089 but also heard the 053 will be a good one also. The tracks I run on really range but a lot of mid and low power is what i need. Local guys say the 089(high end) will give me the greatest range of power but idk which one to get. Thanks.

The 053 is what people run on the 7 Port, if you run the 086 you will have a lot of top end power but you will probably need more low end punch.
