Re: Backfire through carb under load
Yup Don, checked that. That cam is only operated when the actual airchokes are open on top(and all seems fine), which I couldn't check for sure because I had the flame arrestor on. Didn't want to be to careless regardless of how frustrated I am getting<br /><br />Plugs are always black when I take them out, not wet, just black. This should indicate a rich condition, which got me thinking I might want to relook at my timing.<br /><br />I should probably start a new post for it, but here it is. I have always noticed when I am adjusting timing that if the engine is running at ~700 rpm and I set the timing by rotating the distributor to where it is supposed to be to make the timing mark match up to 8 deg BTD, I can turn the distributor and it makes more RPM and the engine runs smoother.<br /><br />I think I might do this next time and keep adjusting then backing off throttle till I am back at my idel rmp range and check timing again. Not sure if this would cause the backfire through the carb I am experiencing, but I am running out of options.
