I’m working on a bit of a head scratcher… getting a 1/5 scale R/C running for my other hobby.

So when I’m not working on my tractors, I have another hobby I’m pretty deep into. The hobby is R/C cars specifically 1/5 scale weedwacker engine powered ones. I have a 1/5 scale Redcat Rampage MT. I’ve had it since I turned 30 as a 30th birthday gift. I’m 46 now so roughly 16 years I’ve owned it. It’s mostly stock except for a tuned pipe. Lately, I’ve hit a bit of an impasse with it though.

 

My conundrum is two weeks ago, I got it out after it sat for two years and got it going. It was dungy and would run but had no top end. It’s usually not much of a speed demon but it seemed off. It usually doesn’t have much in speed as the heavy tires slow it down. I tried to tune it with no big change. Once I brought it back in, I noticed one of the fuel lines was rock hard so I swapped it out. I ran some other fuel line but it seemed too small. It would start but it acted like it was too rich and you could give it no throttle. I have since found fuel line that was the right size but it is still running the same. I also went through and checked the carburetor which was clean, checked the intake gaskets and made new ones if needed. I fixed the exhaust coupling and I vented the gas tank as well. It’s getting gas and spark and I would assume air if it runs in short bursts. I did notice that at the base of the head it was wet. It will start and run now for about 3 seconds then die with no throttle. Any ideas or tips to get this going? I’m thinking I blew the head gasket. If I change the settings on the carb it doesn't seem to do much. Thanks!
