On the toro nero thread you guys where talking about venturies. (restrictors)
I always ran the stock restrictor, because I thought the engine companies put
in the best overall restrictor for that particular engine, but that may not be in
all cases. My FMS seemed to have a rich stumble and miss in the mid to upper
rpm range that I could not tune out with the HSN when using the 9853/41021
w/OD#97t and 25% nitro. I love the 9853's low-end punch. I'm thinking maybe
I should try the 7.5mm or 8mm venturi to get more oxygen in the mix? The
stock is a 6.5mm. Now I'm runnig a 9901 which runs great, but I miss the
9853's punch.
