1971 50 hp <br /><br />Another week, another problem. Motor was running fine and started to bog down. Hard to start, used to start with the bump of the key, and dies when idled down. Under the air intake it is fuel washed and oily. I took off the air cover and the top carb has fuel standing in the carb. When choked it gushes fuel out, motor turns a little slower on the starter, like it got the plug wet. I took the carb off, checked the bowl and jets, the one that can be seen thru the drain screw hole, and all is clean. Re-assmbled and the same flooding. <br /><br /> Do needle and seats get worn to the point of not working? <br /><br /> I plan on doing carb kits in both carbs this weekend.<br /><br /> Other questions while were at it. What is the function of the power pack? On this motor I thought it was just a junction block till I seen one looking for carb kits.<br /><br />Is there an easy way to tell if the motor is putting out as charge to the battery?<br /><br /> Thanks for any info, Gary.

Re: Carb flooding

Sure sounds like a stuck float/needle valve to me. I bet the new carb kits will fix you up. I would think that if the carbs have the original 1971 parts, that, yes, they could be worn out. I would think that the rubber(?) tip on some needle valves could certainly deteriorate over time.<br /><br />Re the powerpack. I know I've read about testing them before on the forum...but don't know the answer off the top of my head. Maybe do a search on "powerpack". I'm sure you find plenty of reading on the topic.<br /><br />Cheers.

Re: Carb flooding

Float seats can get damaged or dirty.<br />Float pins can get damaged or dirty.<br />Float height can get out of whack.<br /><br />Replace the float valves when you take it apart and set the float height according to specs. If you go to the trouble of removing the carbs, do a thorough cleaning/rebuild of the whole carb. Use carb cleaner and compressed air on ALL of the orifices. Don't go by looks, you can't see most of the places where crud lurks anyway.
