Reply to "CB Performance 2.1 l"

I wouldn't know without pulling one and measuring the disti shaft OD, but if it is a Toyota it's probably similar to that from the 18RC engine series, as Toyota used it on a lot of engines until they went with the HEI version (wider cap).  It would be a handy point of info if there is a number or tag on it to identify it for those who might want to use one on a VW engine.  It would also be interesting to know what the advance curve looks like, just for yucks.

@Impala Darrel:  Several on here have cut small ports into the inner wheel well liners for better access to the plugs.  Typically, they fit some sort of water-proof boat access cover for ease of use later on.  Those are both round and oblong - whatever you think fits.  Try West Marine.  Try searching on "Hatch".

I haven't heard of ports like that being installed likewise for the carburetor adjustments.  I found a small tool at Lowes that makes carb adjustment a lot easier, whether you have a flat screwdriver slot or a hex head adjuster.  Lowes SKU 337335 magnetic driver and it's under five bucks.  This version does not ratchet and accepts a 1/4" square or hex drive bit so you can easily get it onto the carb bits with plenty of clearance.

Personally, I have not seen the need for any special tools to get the plugs changed beyond a 3/8" ratchet, magnetic plug socket and a 2" or less extension.  True, they're a PITA to get at, but they CAN be gotten at.  OTOH, I've tried to use one of those Hazet plug tools (In a tool kit on a 912) that Wolfgang showed, and it was impossible to get the plug loosened using that little T-handle - simply not enough leverage on a plug that had been in there for a few years.  Give me a good old 3/8" ratchet any time.
