My Cen .16 MT engine is a little weird... I've run nearly 1/2 a gallon of 10% through it at this stage, but I still spend most of my time trying to tune in the engine (dial it in?). 9 times out of ten it starts as soon as I take it out of its bag and idles ok (I'll get to that later). It runs fine if I gun the throttle and I can tear around for a good while like that, but if I ease it off to about half way and try to slowly accelerate from there it usually cuts. The I spend about 5 mins trying to get it started again. Most of the time it doesnt apear to be flooded, or overheated (its supposed to run a little hotter than norm according to the manual). Just to include: I seem to get a good deal of air in the fuel line is this from the carb? I cant find any leaks (and I sealed the stupid primer on the tank)...

anyway onto the idle... sometimes it idles weird. When I first start it off its quite good, runs for over a min relatively even idle, other times it idles funny, staggered, and other times it idles to fast and the car wants to move by itself. Even other times it idles for a sec and cuts. I do realise that i'm still tuning it, but most of the time theses irregularaties appear without me making any adjustments. I usually adjust to try and fix them!

Sorry for the length... but I really thought that by 1/2 a gallon the engine would be much more smooth and reliable.

If this needs to be moved to the engine section sorry.

Cheers
