What was the main jet stock and what do you have in there now?

[L0w3r55]

the stock main jet is like a 145-147 and i have a 157.5 in there now

One thing to try is to put the airbox lid back on and see if it helps, if it helps that would tell you you are too lean.

If you have it on already, take it off if it helps, if it does then your too rich

By best guess would be a 165-170 but i never delt with youir motor before

But something is telling me the main fell out. Check that first

another way to check is to look at your spark plug to see the condition (ie;lean or rich).also see if the engine runs better with the choke on, if you can get it to run better at a setting of choke keep putting bigger jets in, or if you don't want to mess with jetting go buy an edelbrock carb. they are kind of spendy but are fairly easy to adjust and make great power! good luck!
