Default Engine wont go full throttle

When I advance the throttle to full, it runs for just a sec., then dies back down to idle, and then dies completely. I read another thread where someone had the same problem with their tower .46 engine but I couldnt find it again. Thanks for the help.

The engine may be running too rich...

Or too lean...

How did you tune it?

Most likely an air leak somewhere. Check out the carb throat, make sure it's seated firmly and that the rubber O ring is installed correctly. What happens is that you idle along fine, then when you go to full throttle, you start sucking air from places other than just the carb--this leans the mixture out too much, and the engine dies.

I would consider that too lean. My engine does that if I lean it out at full throttle: revs drop, throttle does little unless fully backed off, engine will die if not brought back to idle.

I've got one of those nasty critters [:'(] -- its too lean -- probably on both high speed and low speed needles. Richen the low speed by 1/4 turn & re-adjust the high speed needle. Don't expect miracles from that mechanical lump -- sell it and get something else before you go nutz.[&o]

I had the exact same problem with mine. I ended up sending it back to Tower for credit on a different make of engine.

I had the same problem, never did like that engine. make sure you low end is plenty rich, that engine runs really wierd if the low end is too lean.

I would call tower and get credit for it. They will most likely give it to ya. Then grab a better engine (AKA Supertigre)
