Re: IO 520 Build on 12 foot Hamant

I think I should clean all the injectors, 1 and 2 are the leanest, I found out that the injector is a one way valve, I can only spray one way, seems a simple way for an injection system

Re: IO 520 Build on 12 foot Hamant

Slidin Gator The rear jack, I don't know what to change with it, looks like I can only push down with it unless I attach it to the runners and be able to lift up with it, the engine stand is welded to the angle iron that is attached to the runners of the boat, no adjustments there. If I need to flip...

Re: IO 520 Build on 12 foot Hamant

Hi Slidin Gator The engine aft is as low as it can go, would need to cut the engine stand down to lower it. Would Raising the aft end of the engine cause more nose dive or hop ? My 35 gallon gas tank is below my seat, I could put it under the engine if I raise the rigging above the boat sides in ord...

Re: IO 520 Build on 12 foot Hamant

Yes the trim tab helps till I get over 45 then the bow digs in and splashes water out ahead of me and I get wet. Yes I have 2 jacks, one in the back 16" from the transom and the other is 4 feet from the transom. I haven't checked the bottom, has poly on it, it looks good. I'll take some pics of...

IO 520 Build on 12 foot Hamant

I found this older 12' Hamant hull with rigging that was in bad shape, I had already purchased an IO 360 Lycoming that was off an Airplane with prop strike for this Hamant. But then I found an IO 520 Continental for sale and bought it. Both engines I bought with out hearing them run first, just took...

Re: Tuning a Lean Running O-540 & 6AA / M5-4 Carbs

Slidin Gator, I always use Mystery Marvel Oil's magic in my aircraft motors, both in the fuel and in the oil, they say it helps in the seating process on breaking in new cylinders as well, 1 quart in the oil and 4 oz per 10 gallons gas. I have been using it for the past 30 years.
