Just installed a 96MM piston and cylinder set into our 75 914-2.0. Fuel injection has been removed and replaced with a 32/26 DFV. Upon restart, there's a lot of backfiring both through the intake and exhaust. Runs like #$$#@%!!! with no power whatsoever. So far we've reset the carb per Weber initial set-up procedures and performed some initial timing. It idles, but hydrocarbons read at well over 8000 and the CO% was at 5 to 7%. So we're probably real rich. Probably should be rejetted...
Question.... when we installed the piston and cylinder sets, we also performed a valve seat rework (with a Neway by hand). All valves were verified to seat. Do you think the backfiring and no power condition is due to any other cause besides the carb and timing set-up????? |
