Hi all
Top site & have found it very informative but can not seem to pin point what is going on with my motor.
I have just recently purchased this boat & motor & have been having issues every time i put it in the water go's ok at first then would stall as soon as i put it in to gear tho seemed fine on the muffs at first but now when i put my hand over #1 carb the engine doe's not change & the carb starts to flood in the venturi with fuel & when i do this to no 2 & 3 carbs it near stalls the motor.
Has good compression 118psi on # 1 & 3 & 115psi on # 2 has very strong blue spark on all 3 cyl
Since owning it the carbs have been completely striped & cleaned including the removal & replacement of the small welsh plugs in the carby & floats reset.
New power Pack
3 x new coils as the old ones the leads were that short they only just reached the plugs & at $30 each thought i may as well replace the complete coils with leads
New plugs champion QL77JC4
New fuel pump after kitting the old one & not being able to stop it from leaking
Have done link & sync
I have swapped reeds & carby from #3cyl to #1 cyl to see if the problem change to no 3 cyl & it did not make any difference when putting my hand over the carby,at the moment i don't have a socket big enough to remove the fly wheel to check the stator.
Engine is a 1975 70 hp Johnson 70ESL75E 1975.
Any help in giving me some ideas on what else i could check or test would be appreciated.
Regards Shaune
