RE: another darn ryobi post (ryobi performance modification, analysis and comparison)
Combat,
I mounted my ignition today with a little shadetree engineering. I'll try to get pics tomorrow night. Looks like I'm getting good spark, but anyone on here have any suggestions as to how far away the magnet can be from the pulse switch and still work okay? I've got a pretty good gap, I'd say about .035" without measuring it and seems to work fine. I noticed, however, that while rotating the crank back and forth with the magnet under the switch that it would 'miss' a spark here and there. Is this normal? I wasn't going full revolutions, just rocking it back and forth under the switch. I'm waiting for the JB Weld to cure now, but I am going to try and run this thing for the first time tomorrow. Here is my setup:
Older jug, two single large ports (and no 'slits'), large crankcase, factory 7.2mm carb, CDI set at 28deg, stock unmodified muffler, new piston (2 ring, no gap), cylinder base gasket installed (piston hits jug without it), non-recessed reed mount with stop set at 1/8" and no bends, except to get the reed to sit tight on the backplate with no gaps.
I have an 11mm carb to try after break-in and some initial test numbers. I am also looking for a decent muffler. Mine looks like it is crimped together, so I am reluctant to break it apart to gut it as it probably wont seal after getting it back together. Suggestions?
