:helpsmilie: I've been trying to get my Chaparral ST 80 (Fuji engine) started for months to no avail. The spark plug is remaining bone dry and I can't figure out why. I've replaced the spark plug, coil, point (the condenser is fine so didn't replace) and I have spark. Not the problem. I've checked for compression, and it's 110+. So not the problem either. I redid the gas tank, cleaned the inside, POR 15'd the inside, replaced the petcock and filter, and gas is easily flowing to the carb. I originally tried cleaning the Mikuni carb that was on it, multiple times, and when gas was still not getting to the engine, I just decided to buy a brand new one that is the exact same model (Mikuni VM18-144 Round Slide). And yet gas is still not getting from the carburetor to the cylinder. I bought a NOS exhaust pipe that was for the Chaparral and put that on there as it didn't have an exhaust when I bought it so I can't imagine that's causing any problems either. The only thing that is not stock and that I make shifted is the air filter. The one thing I can think of as being the issue is maybe too much air is getting into the carb and not creating enough vacuum, so this weekend I tried blocking things off and only allowing a small amount of air to go through and still nothing. I've tried push starting this thing and nothing, and kick starting has been a complete failure. I've gotten a few pops out of it (like one) each time I've dumped gas into the spark plug hole directly but nothing more than that. At this point I'm at a complete loss as to what's going on. Fuel is definitely getting to the new carb as it now keeps leaking out of the overflow/air tube on the bottom of it which was also happening with the old carb as well, but it never seems to be making it to the engine itself to actually ignite. And FWIW, I don't have any wiring hooked up either. I've been attempting to get wiring to work with a switch that I had but that hasn't worked out so nothing's hooked up. There is no kill switch.
If any of you have any tips on what else I could try it would be greatly appreciated because at this point I'm at a complete loss. :cursing:
