I can take the carb off of any healthy two-stroke glow engine and get it to start on one or two flips with only a few drops of prime. If the fuel tank height is proper, the carb has nothing to do with starting the engine. The carb only works when the engine is running and flowing air through the crankcase/cylinder. This is not happening when starting the engine by hand.

My G2300 throttled just fine with the stock carb. Later, some G2300 engines got out of the Italian factory with the wrong barrels in the carbs. This is a matter of record. Blame it on one of the sons that was running the business into the ground.

Apparently, the new G2300s from China have the proper groove in the barrel, so there is nothing wrong with those carbs that a decent engine tuner can't adjust properly.

The big Tigres are not set up for nitromethane. More than 2.5 to 5% at sea level is asking for a very cantankerous engine. Ditto fuel containing too much oil. I really got tired of seeing the big Tigres overheating and deadsticking because those flying them insisted upon using too much nitro in the fuel. Ditto the ASP 1.08 Redhead. Mine ran great on 5% nitro fuel with some castor oil in the mix. I used to watch several others at the field curse, stomp and declare how the big ASP was junk. Their fuel was 15% nitro Cool Power. Go figure. That fuel is good for the right engine. It just wasn't good for an engine with very high compression.

Why some people don't look at others that are succeeding and then emulate their behavior is something that puzzles me to this day. I don't look to see who is flying the largest or most expensive airplane. I don't look to see who is strutting around in their fancy clothes and telling others what to do. When I have a question about a product, I look for the guy that is flying it successfully. That'll work every time.

To this day, I don't understand why some folks are so enamoured with fuel using more than 5% in a two-stroke engine.
