That sucks! You may have to invest in one of these if you're gonna keep messing with that chit.

Brett, is that an impulse tapped on the side? If it is why not use the case tap?

After modifications and machine work the case tap was not usable...I think the cause was not enough metal in the jug and to much nitro....oh well gotta find the limits somehow right?

I'm told with some of the old 392 hemi's having only 10 head bolts, that you could just about see the heads bounce under a good load of nitro. That is from more than one source and with 9/16" studs, after going away from the 1/2" studs.

We always put 3 gallons of alcohol into engine first to put heat into it as it was supposed to be easier on it. Some of the Barrel valves were harder (more aggressive) than others as well. Though I dunno how that may apply to a saw. I thought an injector like a street bike oil injector directing the fuel above the crankcase may be a better route to go when heavy loads of nitro are used. Two advantages would be, the bottom end may getting more oil as Nitro kills oil, even 70wt nitro oil. And you can better direct the fuel in volume control and placement in the cylinder, like the down nozzles in a top fuel application.
