No risk of damage to jets in this case as I was just clearing/checking the fuel way in the carb body between the inlet and the float valve. Interestingly, the specific jet cleaners that I bought from...

Finally fixed it! Tried cleaning the carbs again. Guitar strings and carb cleaner spray seemed to be pretty good, but not convinced of any blockage. Tested the carbs on the electric fuel pump with...

Thank you for the advice. I think my summary is that an ultrasonic bath might do the job, but it is not as cheap as I thought, which makes the new carbs possibly the better bet as they are a pretty...

Ultrasonic cleaners - Evinrude 70

I'm still struggling with the Evinrude 70 (old, late '70s?). It idles fine and will go for a bit, but then the revs drop off as fuel starvation sets in. It is possible to make it go by pumping the...

I'd be interested in an outline of how you made and attached the fibreglass tubes. I have an elderly rib that is probably not worth retubing, though it will keep going a bit longer yet.

There is a slight leak from the crankcase side of the pump. I think it is through a chasing flaw rather than the diaphragm, but it is hard to be certain. I didn't think to check the crankcase pipe...

Evinrude 70 fuel pump

Back to the ancient Evinrude 70. I had a burst of enthusiasm yesterday and so stripped the carbs and fuel pump. All were clean as you like, but a few of the fuel pipes a bit lose on the in side, so I...

OK, now I need someone in the Bangor Caernarfon area who will touch 30 year old engines and while I am at it a supplier of rocking horse ... It looks like I will be doing it myself!

Favorite outboard mechanics Bangor/Caernarfon area

I could really do with having the dodgy 70HP engine fixed as I want it for next weekend and just do not have the time. Can anyone recommend cheap, reliable outboard mechanics in the Bangor/Caernarfon...

Testing the fuel pump - old Evinrude 70

Can I prove the fuel pump by bypassing it and having a passenger pump the primer bulb like mad? I don't really want to spend on all the bits to rebuild the carbs without a bit more evidence that it...

I have seen a HT problem that left an engine that ran fine at all but WOT, where it would miss like mad/die. I don't think that could be what we are seeing here because it will surge when on the edge...

Next problem, old Evinrude 70HP surging and no power

Having got the idle RPM to a sensible level, I took the boat out on Saturday. Everything worked well, except when I tried to open the throttle. WOT would stall the engine, judicious increase of...

I ran it with muffs. I am glad that I didn't take it to the water or I would have been tempted to put it in gear, which would probably not have been a good idea at that RPM!

Thinking about it...

I've managed to leave the bit of paper behind with the model and serial number of it... I'll post it later. It is probably 1980s

Old Evinrude 70 idling far too fast

I have an old Evinrude 70 that was bought as "hopefully OK". I finally got it on the boat and tested it yesterday and it ran nicely, but idled far too fast. I am pretty pleased it ran at all and...

Thank you. I am sure there will be other little bits I need. A set of carb gaskets is just about guaranteed. I might get lucky though.

Thanks, yes that appears to be the right one. I am too skinflint to pay that though, especially as I have experience of what the import duty could cost!
