outboard runs on full choke only


don y beimborn

Question

After a winter layup, took our 9.9 1979 Johnson up to the lake with last year's gas. It ran fine for two days, then I had the resort guys fill the tank. Then it started to run poorly. Could get speed only with the choke out and by the end of the week it would run only with the choke out. Plugs are black and wet. Might be oily.

What can I do? Need to go fishing Wednesday.

Take the carbs off and clean the pilot jets. If you have no experience in this field find a mechanic. The proper way is to have the carbs cleaned completely, needle and seat replaced, and re-adjusted. Call a shop, quick!

Sounds like a vacuum leak, the choke restricts air to the engine and creates a rich mixture needed for starting the engine, a vacuum leak will lean out the mix until you close the choke. Check the bolts that hold the carburetor to the intake manifold sometimes they can work loose. You will probably have to pull off the recoil start to get to one of the bolts. If the bolts are tight check the gaskets on both sides of the intake manifold.

First I'd get some new gas, and if that didnt work all the problems out, then I take the other steps people have mentioned.

      The majority of docks can't be put it. Water is over the top of pretty much every permanent dock.  Very few docks are in.

      Crappies are all up shallow in the south metro. Caught this one shore fishing with a beetle spin from a more secluded lake without much access. All of the crappies were between 7-9 inches with this 11.5" being the exception

      A co-worker reported they had some the best fishing ever on V last weekend.  Trolling 6-8 feet in the morning with HJ10’s.  Where the water temps were in the mid/low 50’s

      Those campsites are right across the water from us. Seem pretty well protected and I haven't heard of challenging over there. Holiday weekends they fill up very fast

      My son camped on Hinsdale with his aluminum runabout. Nice site but walking across the hull parked on uneven ground he separated a couple of the rivets.

      Thanks "Skunked Again!" I searched old posts and it sounds like my fiberglass boat might not be the best rig for Hinsdale. Still, would appreciate more advice/input.

      I don't know about either of them, but welcome to the forum.

      I destroyed my main propeller saving a neighbors dock section from ramming my other neighbor's dock. Definitely watch out for each other out there.   Raven77 - on the plus side of the high water, the floating swim platform that you sold me the other year was able to just float off of the rocks that I had beached it on. No need to do any heavy lifting this season! I'm glad that I tied it to a tree as usual.

      On the south end...  A great 2022 MN Fishing Opener for most anglers.  The walleyes and saugers are hungry and the bite is on!  Good numbers of fish caught. Lots of big fish amongst the eaters.  Most anglers were vertically jigging in 6' - 20'.  Anchor up and jig over the side of the boat.  A nice mix of sizes.   The water is a bit dirty on the east portion of the south shore due to runoff from the rivers.  A bright jig with a minnow is the most productive. Reports were also good from the west portion of the south shore.  A bit cleaner water and equally good bite.  Lots of big fish mixed in with eaters.  Some anglers fishing on structure or on the edge of structure where available. On the Rainy River...   A lot of walleyes in the river as predicted, but the current is ripping and the water is a bit dirty.  Those who found slack water often found fish.  The norm was 6' - 15' with a bright jig and minnow.   Typical spots in the main channel were tough to fish due to high current.  The fast moving water helped to congregate fish.  Once you found them, there were normally good numbers. Sturgeon fishing is closed until July 1st.  July 1 - Sep 30 is a sturgeon keep season with one fish per calendar year 45" - 50" or over 75". Up at the NW Angle...  A great jig bite up at the Angle for the opener.  Most fish were caught in 6' - 20' adjacent shoreline structure, neckdown areas and on some shallow flats. Again, a jig and minnow was by far the most common method vertically jigged below the boat.  With cold water, a subtle presentation.  Both fatheads and frozen shiners worked well. Various ways to travel to the Angle. 1.  Drive through Canada to the Angle  (must be vaccinated, no covid test required) 2.  LOW Passenger Service (charter boat service across the lake avoiding customs)  3.  Lake Country Air.(fly from various Midwest locations to LOW and NW Angle) 4.  Take your own boat.  (Safety first, this is a 40 mile ride over big water)

      Greetings all! Our group (two boats/five guys) is looking at fishing/camping trip based at Hinsdale Island Campground or Wake 'Em Up Bay Campground in about 3 weeks.  Can anyone advise about Hinsdale, especially the shoreline for landing boats? (Is it sandy or rocky? Mostly protected?) We're also wondering how busy both campgrounds are? We've stayed at Wake Em Up,  but that was 6-8 years ago and it was mostly empty...just the host and 2-3 others. Nowadays, do either or both fill up on June weekends? (We'd probably arrive on a Saturday, stay most of the week.) Of course, we also welcome suggestions for walleye techniques, depths, etc. We tend to fish smallies during the day and chase eyes in the evening.  Thanks in advance for your help!
