Re: 1983 Formula F20SC
SIGH ... engine issue is not resolved..... Here is what has been checked so far.... Removed anti siphon valve.... changed fuel filter.... checked timing... dissassembled carb and check float levels and free movement of needle and seat... checked timing again... ..... tested different engine trim postions.... the last thing I tried was bending the arms of the secondary valves just slightly to allow the fuel to begin flowing a little sooner
also here is a little more detailed description of what the boat is doing along with todays observations.... the engine starts and idles fine and runs fine until between 1800 and 2200 rpm and then the RPM's drop and then rev back up some and then drop and rev back up some... this seems to be happening just as the secondaries begin to open. Furthermore it begins popping out of the carb ALWAYS the CARB never the exhaust. I am at my wits end at this point there is so much new stuff on the motor I do not know what to do next. It has new heads, new distributor, new manifolds. It seems to also be burning a little oil but that could just be surface oil as I had an oil leak. I am also going to post this in the engine help section
... good old mertons I am going to order some more tomorrow cause it is great. However if you look at todays photos you will see some whitish stuff ... thats my a cabosil/microballon/resin mix...
