I recently purchased a 350 and I got it started finally yesterday. It has a water cooled head, 38mm carb with 186 main,aftermarket snorkel and a K&N filter, br9es plug, DG pipe and silencer and has 125psi of compression. Once I got all the water out of the case from the last owner leaving it out in the weather!! I did get it running. It Idles with a little spitting but if you give it any gas at all it picks up some RPM then bogs and shoots flames out of the pipe. Any ideas? Is it just too lean? I have wrenched allot of 2 strokes and never had one backfire this violently!
Thanx in advance!
