Is that what you found on yours? Mine does have the Walbro on it, so maybe that's a good thing.
Yep. The popoff pressure was over 40lbs. Even with the pop off pressure fixed, it still wouldn't hold a tune. Slapped on a 199 walbro, and bingo, no more probs.
First I've heard that. My ported OE has the 357 Zama carb and it does fine?
Once u go so far with the port work, they just won't feed it. Myself, randy and terry all had the same problems, all with brand spankin 357 zama's.
