You were correct. Found my # 3/4 coil had a high resistance fault on the port primary connection. Read 18 ohms installed an open when I removed it. Ordered and will update when installed and tested....

Well it sure isn’t the VRO. Tried that and the new pulse limiter and hose. I’ll check compression tomorrow. I’ve got a spare power pack. I’ll try that next and check some voltage readings.

Replaced the spark plugs and checked the throttle/timing arm synchronization and took it out today. Ran much smoother but had the same issue. Weak holeshot and reduced maximum rpm. Put it back on the...

Is it normal to have to clean or replace the plugs often? I usually notice it when I’m around 5200 rpm I will have a dead moss. I wasn’t running that fast this weekend so I didn’t get that clue. It...

Went on a weekend fishing trip and on the next to last day noticed putting it on the trailer that the engine stalled when I pushed the boat up. Next morning it took off ok and I had my wife with me...

There is no tension on the arm, just push it over until it touches. Then make sure that your throttle plates and your timing begin to move at the same time. There are other things that may cause that...

Thats all good
i did finally find my air leak with clear hose, was at the inlet to the engine on the port cowling. I ended up removing the fuel bracket, rebuilt the vapor pump, new float, needle...

I should've paid more attention to your wise advice. I decided to remove the fuel filter and check it, found that the gasket was missing and the o-ring a bit loose. After a a field expedient repair...

I also ordered a BRP bulb and hose kit, new seal for the fuel filter and the outlet from the fuel bracket fitting that goes to the VRO and several hoses. I have an Anti siphon valve already on the...

I will order parts to o/h the vapor chamber and I might as well order another VRO. Thanks Champ for the offer but I'm not inclined to borrow your stuff. I'll pick up some clear Jose and see what I...

Could I remove the oil inlet section off my new pump and install it on my old pump? The old VRO looks as if someone just removed the oil inlet. I suppose I could look at the manual for that.
I can...

I used 5007420. The right one. Just curious if it could have a problem that causes this? It's an expensive guess

Should I try another VRO?

What kit? I installed a new pulse limiter with the VRO.

Is is there a kit for the vapor tank or do I have to order individual parts?
Thanks for the help by the way. This is my first two stroke...

Yes it is timed and synchronized. New throttle cam roller

Yes. I thought that would be the fix. I had a throttle cam roller with the sleeve missing. Replaced that. Did the complete static timing procedure and synced the throttle plates and cam roller/...

I have not rebuilt the vapor tank. I replaced the fuel filter prior to replacing the pump with no issue. I did not use a BRP bulb, it will stay firm for a bit but if I am pumping hard to check for...

That is confusing
It is a new VRO. I recently "replaced" the old one. The boats previous owner disabled the oil mixing on the VRO. And was mixing 32:1 in the tank. Talk about smoke! I mixed 50:1...

I have rebuilt all the carbs and installed new bowls. I did swap the main jets into the new bowls.
I had very warped bowls before but even that didn't cause the fuel to go back to the tank

I have a 99 Johnson 150 j150plees
I've had it about 6 months and it's been an ongoing project. Rexently traced the VRO due to the oiling portion having been taken off the old one. Ever since I have...
