Rich = to much gas

Lean = not enough

 

To lean and you'll burn down your engine real quick.

Just remember Lean is mean rich is a bitch. Your better off starting rich than lean just remember that

[2/2 many banshees]

lean runs good one time rich runs for ever

[Wildcardracing]

Lean=too small of main jets, needle too low, too small pilot/not enough fuel per intake air charge=burn down

 

Rich=too large of main jets, needle too high, too large pilot/too much fuel per intake air charge=poor performance, fouled plugs, hard starting

 

Stoich=perfect jetting/optimal fuel-air charge=optimal performace, easy starting, long engine/plug life

I knew this stuff but it's always nice to hear it another way. Maybe a little catchy and easier to remember. :thumbsup: :thumbsup: Nice job. The only stupid question is the one you don't ask.

ive seen this shit happen before so be careful

 

rich=not so mutch power and uses more fuel

 

lean=more power,use less fuel, and if not corrected will land you a fucked up engine.

 

i know from experience dude,,not me but a guy i know,,no no but you could imagine what itd be like!!! :biggrin:

[250Rho]

yes,, better to ask then to end up with a toasted motor :biggrin:

lean sounds like it's running inside a tunnel....popping and gurgling.... idling real high then cutting out...@ WOT cuts in and out or doesn't run at all

 

rich sounds dirty and makes lots of smoke... low idle or no idle...@ WOT it just dogs.

You can run rich all day long and only have to worry about plugs. You can only run lean a little while and swap out the motor.

 

Rich the engine will bog some but will run. Lean the engine will surge and finally die.
