When running on low revs the engine stops after a while and can be a little difficult to start again.
What do you think about this, I guess, well-known problem?
No I haven't checked compression and spark when it is hard to start because by then I am out on the lake. It is not difficult to start generally, only when it has stopped by slow running. I am going to wrestle with the low speed jet again and see.
May be plug fouling if it happens after extended trolling. Take the plugs out and see if they're wet. If so, you can widen the gap a little, to .035-.040" or go to a little hotter plug. How does it run at full throttle?
