Subject: elan timing troubles

Author: Ted

[ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 18:26:03 01/06/11 Thu Contact points needed replcing on a 1985 elan with a rotax, single cylinder 247 type engine. OEM points are discontinued so got a KIMPEX replacement set. Set points at .016 then proceeded to timing. Used a dial indicator with rod setup through spark plug hole. Used a "dim" - "bright" bulb setup with battery to indicate points opening and closing. After holding the timing advance lever full open (247 type engine), rotated engine until light went from bright to dim (points opening), and measured distance to TDC on dial indicator. Service manual calls for timing to be .147 to .167 BTDC but after loosening three lock screws that advance/retard timing the most I can get is about .135 BTDC. Rechecked points (still .016), camshaft looks fine (no worn groove from points and no play when slid on crankshaft), even tried good used replacement camshaft from dealer. Crankshaft is not twisted, bent to alter timing. Advance timing lever operates smoothly and is properly aligned in camshaft slot when flywheel is installed. OEM to KIMPEX point sets not exactly the same? Any suggestions to explain this situation are appreciated!! [ Next Thread | Previous Thread | Next Message | Previous Message ]
