Hi, I have the Tower ST-15 stadium truck and while I am pleased with it's performance I don't like the air filter setup, it has the cup with two foam disks. I have 8 tanks of fuel through the truck and I have had to wash the elements three times already to get it to run. GRanted it is dry and dusty here in Wyoming and I have been running it a lot in gravel and dirt, but I just ain't very happy with it. I also noticed that if I put a couple drops too much filter oil in the thing that it won't let the engine run proper. I experimented running it without the filter on the street and it runs very fast, then I put the filter on and it will stall the engine, or if it runs it will slow it down a lot. Since I went the cheapskate way and bought this truck instead of one of the popular ones, I don't know what aftermarket filter will fit it, and I havn't measured the carb diameter yet, but I can if it would help someone to help me match a good filter to this truck. My use for this IS NOT racing, nor will it ever be, but even running around the yard and at the park I would like the engine to be performing at it's best.

Thanks in advance for your help,
George
