Hey guys, new to the site and new to mini trucks! Got this guy and the previous owner had done some mods and it runs pretty poorly so I'm trying to figure it out. I put in new plugs and plug wires and the cap and rotor seem all right but it runs pretty poorly. ( Idles okay and rev's all right but under load lacks power completely and the idle tends to stay up once you start driving until it bogs down and dies) There is an aftermarket 32 mm carburetor on it, but I'm not sure it's set up right. I'm getting ready to tackle vacuum leaks and jetting on the carburetor, but the first thing I noticed that I have a question about is what appears to be a breather on the motor that vents back into the cold air intake between the air filter and the carburetor. The tube runs from the top of the block and comes into an inlet that's formed into the cold air intake tube. My question is this: there is a ton of air coming out of that tube so it's forcing air at a pretty high rate into the cold air tube, so I have to turn the idle way up and I'm guessing over fuel the carburetor to make up for all of this high volume air being forced in to the carburetor. Should there be a ton of air coming out of that or is that a sign of excessive blow by from the cylinder rings? Secondly, is there a PCV valve location to balance this discharging air because I've not found that yet? Sorry lots of questions but I'm starting to dig into this guy and any help from experienced folks who have worked on these would move me ahead quickly. Thanks in advance!!
