Fired up the old girl for the first time in over a year. Had it in a full trash can of water. It took around 5-10 seconds before it started peeing. At idle it streams out (about 2-3" then falls), at ~3000 rpm it pees out ~7 inches before it arcs and falls. At a very (very) low (sputtering low) idle, it drops off and just dribbles out. <br /><br />Is this a good sign, or do I need worry? Is anything out the pee-hole at idle good? Do I need to expect a 20" stream?<br /><br />Thanks in advance!!!

You may want to replace impellor. Its cheap and could save your engine.It is not that hard to replace.

How does the trim tab come off? I see the other 4 bolts. Is this something I _NEED_ the manual for, or if I disassemble / reassemble in the same way .. ???

There should be a plug in the case just above the trim tab. Remove the plug and way down in there is a 3/8" allen head cap screw. If it's anything like the trim tab on my '69 650, it'll be a bear to turn. Definitely get a manual.

You should change impeller. At idle it should pee pretty good not 20''.
