Default Carb rebuild or replacement?

So its been awhile since i used my HPI nitro MT its an old model with the .15 FE

It ran good before i put it away, i pulled it out years later and i couldnt get it to stay running. I pulled the carb apart cleaned it put it back together, and it almost ran good, it idled the longest i could get it to, maybe 30seconds.

Mostly what I've noticed is bubbles appearing in the fuel line, i have to prime the crap out of it to fill the line, then i get it idling irratically and then it stalls and bubbles in the line.

Almost like maybe a vacuum leak. Idk, I'm about to swap the engine or maybe carb?


This older model has a 1 speed transmission, not sure if i caj swap in a newer more powerful engine? Not sure if the drivetrain can handle more power.

depending on how much fuel has been through the motor, you might be better off just buying a new engine.there are some nice .15 and.18 engines out there that can be had for low prices.
