Hello all, I'm looking for some help with the above engine, its becoming a bit of a nightmare. I purchased it cheap as a Non Runner as it wasn't pumping any water. I believe its in need of a Carb rebuild and then needs to be re-timed, but I cant find any manuals or guides. Hear is where i'm at so far:-
Changed Water Pump Housing and Impeller and it started pumping water but wouldn't start.
Did a basic clean of carbs and would Idle "Ok" when upto temp but was very lumpy and weak.
Ran compression test on engine, both around 125psi.
Followed a guide I found on here to change the idle etc via adjusting the linkages, this has resulted in a better idles but still cuts out ever now and again (restarts fine)
However I now seem to have no power. Boat will idle and I can dial the revs up but probably only hit about 8 knots (4m Avon SR4), I couldnt get it to plane or lift out the water, I'm guessing I've c*cked the timing up by playing with the linkages. Any help would be appreciated, a manual would be amazing. I have timing gun etc, just not sure on the settings, or set-up process.
Thanks in advance.
Tom
